🌍 Welcome to Clean Earth Fun Facts! 🌍

Welcome back to Clean Earth Fun Facts, where we share the most fun and enlightening facts about our beautiful planet and how we can all contribute to keeping it clean and green! Today, we’re addressing a significant environmental issue: smog.

🌫️ What is Smog? 🌫️

Smog is a type of intense air pollution characterized by a mixture of smoke and fog. It typically arises from the burning of fossil fuels, which releases a complex mix of chemicals into the atmosphere. Smog can have serious health and environmental impacts.

🌟 Fun Facts about Smog 🌟

Origin of the Term: The word "smog" is a blend of "smoke" and "fog." It was coined in the early 20th century to describe the thick, grayish haze that blanketed cities during industrialization.

Two Types of Smog: There are two main types of smog: sulfurous (or "London smog"), which is caused by burning coal, and photochemical smog (or "Los Angeles smog"), which is formed when sunlight reacts with pollutants like nitrogen oxides and volatile organic compounds (VOCs).

Health Effects: Exposure to smog can lead to respiratory issues, eye irritation, and long-term diseases such as asthma and bronchitis. It's particularly harmful to children, the elderly, and those with pre-existing health conditions.

Global Issue: While smog is commonly associated with large cities, it can occur anywhere that has significant pollution sources and the right weather conditions.

🌍 How to Reduce Smog 🌍

Switch to Clean Energy: Using renewable energy sources like wind, solar, and hydroelectric power reduces the amount of fossil fuels burned, thus cutting down on smog.

Improve Public Transportation: Encouraging the use of public transport, carpooling, and non-motorized transport like cycling can reduce vehicle emissions.

Adopt Eco-Friendly Practices: Industries can adopt cleaner technologies and practices to minimize emissions. Individuals can contribute by using energy-efficient appliances and reducing waste.

Support Policies and Regulations: Advocate for and support government policies aimed at reducing air pollution and promoting environmental sustainability.

🌿 Fun Fact 🌿

Did you know that plants can help reduce smog levels? Certain types of vegetation, like trees and shrubs, can absorb pollutants from the air and help improve air quality.

Deep-ultraviolet birefringent hydrogel based on 2D cobalt-doped titanate

A birefringence based light modulator that works in the wavelength region of < 350 nm plays a vital role in DUV beam shaping, high density data storage, semiconductor micro-nano processing and photolithography. Actually, a series of DUV birefringent materials, including single crystals of α-BBO, MgF2, Ca(BO2)2, and α-SnF2, have thus been made and commercially used. However, these birefringent elements have fixed birefringence, limiting their capability of continuous light modulation.

Liquid crystals (LCs) are another kind of birefringent materials, of which birefringence is tunable via the molecular alignment by external electrical or magnetic stimuli. Up to now, the commonly used LCs are mainly based on organic molecules or polymers, which are not stable under DUV light due to photochemical degradation effects. Meanwhile, DUV can also induce free radicals in some organic groups, and initiate their polymerization, which disorders the alignment and the resultant birefringence of LC. Therefore, organic LC cannot modulate DUV light.

In a new paper published in Light Science & Application, three teams of scientists, led by Professor Hui-Ming Cheng and Associate Professor Baofu Ding from Shenzhen Institute of Advanced Technology, CAS, Professor Wei Cai from Xi'an Research Institute of High Technology, Professor Bilu Liu from Tsinghua University, China, cooperatively synthesized two-dimensional (2D) inorganic cobalt-doped titanate (CTO) LC by using a wet chemical method. The 2D LC has large magnetic & optical anisotropy as well as high transmittance of > 70% in the wavelength of 300 ~ 350 nm, which enables the transmitted DUV modulation in a magnetic and portable way (Fig. 1).

I went down a few rabbit holes while researching the Advent Calendar last year, that didn't make it into the queue because they got too long or went too far afield. Here's one of them!

One thing you notice when you watch a bazillion videos about old games consoles is how the design of circuitry has evolved. If someone says 'circuit board' today, you think a light piece of leafy green board, filled with parallel lines of copper at 45° and 90° angles, dotted with lots of tiny inscrutable plastic and metal doodads. But it took a long, long time for them to get that way.

If you look at really old circuit boards -- and I mean really, really old circuit boards, like from the beginning of the transistor era, they look completely different. They're brownish, for one thing. And kind of... wiggly?

Apologies for the transfer quality. It's not your connection, it just sucks. This piece appears to be some sort of promo-tainment thing from Tektronix themselves, from 1969. The rounded corners and bluish fuzz at the edges is an effect called 'vignetting', and it means this is originally from a 16mm film reel. There's no earthly reason for film to look this terrible. The uncentered picture means someone copied it by pointing a camera at a projection screen instead of bothering to get a proper kinescope setup, and the fact that it only goes up to 240p makes me feel like it was originally transferred over two decades ago for RealPlayer and nobody bothered to fix it for YouTube. VHS is about 240 lines, but if this were a crap transfer from a VHS tape you'd also see scanlines. It's possible there's a better copy at VintageTek, a museum dedicated to the history of Tektronix; they are an all-volunteer institution, and they probably have more important things to funnel funding to than updating their YouTube channel.

Point being, it looks like porridge and I'm sorry, but at least the content is interesting.

The brownish color, which is actually from an evolutionary stage earlier than what's covered here, is because many early boards were milled of bakelite rather than electrodeposited onto a glass or fiberglas backplane. If you want to see some of what that might have been like, you can hop over to Usagi Electric. He uses CAD to mill boards, rather than the photochemical process described by Tektronix, but it's pretty much the same idea. He does a lot of it in pursuit of his mad obsession with building a vacuum tube computer here. (If you're curious, his logo says うさぎ電気, "Usagi Denki". "Usagi" is Japanese for rabbit or bunny -- there is one who appears at the end of some videos -- and the spelling of "denki" here specifically means electrics, as opposed to 電機, which is usually rendered electronics. It still pops up in the names of some engineering or technology firms, but generally only the really old ones.)

The wiggly nature of early boards is neatly explained by watching the drafting process, starting about three minutes into the video. It was originally done by hand. The rest of the half-hour video goes through the whole multi-stage process, but the gist is that when you lay out the board, you draw dark lines where you want the conductive traces to be on the final product. To get a consistent size, tape is used for "holes" and tape lines are uses for the traces. If you've ever used stripe tape in nail art, it was apparently something like that -- vinyl tape with a bit of stretch, so you could curve it around. It was a methodical sort of art form. Ever solved one of those "connect the same-color dots without crossing lines" puzzles? It's basically that. If you can't find a topologically-appropriate solution on a single plane, you can produce boards with traces on both the front and the back, as Tektronix does here, and these days you can actually bury traces in internal layers as well. It's just a pain and makes the cost go up exponentially. 

The mention of "holes" is interesting. Early circuit boards were nothing but holes. Everything had legs and was soldered on from the underside. Today these are known as "through-hole mounted" components; the alternatives are "surface-mount" components, which are generally smaller and fiddlier to solder on by hand, but considerably easier to lay down and solder in place by machine. Surface-mount technology has been around since before this Tektronix piece, but remained NASA-grade esoterica until the automated assembly process became cost-effective in the 1990s. Today the conductive holes are referred to as "vias" and the little medal dots surface-mount things are soldered to are "pads".

I'll also note that they show the automatic soldering process for these boards late in the video. It involves skimming the boards across the surface of a pool of molten solder. Solder in the 1960s contained a lot of lead. I would not personally like to be in that room. Today a machine places little surface-mount doojiggers in place along with solder beads, and then melts it all very gently in a very hot oven until it all melds together, not unlike a pan of slightly too-runny cookies. If you do it right, the surface tension of the solder keeps it on the pads and out of the traces. This is particularly useful for placing CPUs, whose myriad tiny pins in a tight grid would be far too difficult to solder by hand, and the origin of "reflow" repairs for electronics that are exhibiting symptoms of flaky solder joints.

The "silkscreening" process here does not use silk, but originally it did -- it was invented in Asia, logically enough. The gist of it is that you take a piece of finely woven mesh, traditionally light silk but in modern times also metal or synthetic fiber, and you plug up all of the little holes in it in the areas where you don't want ink to get through it, usually with some sort of water-repellent substance. In the days of yore, you painted on some kind of sap or wax, but nowadays it's usually a light-sensitive plastic that's scraped across the whole mesh, topped with a stencil that is opaque where you want ink to flow, and exposed to UV light that sets the substance. The unset areas that were in shadow are rinsed clean, leaving the mesh permeable in those places. The ink emulsion is then applied to the printing surface beneath in the reverse process: Ink is spread across the mesh, then squeegeed through with enough force to push it through the holes in the weave and onto the surface beneath. The dots of ink bleed just enough to flow into one another, producing a solid area of pigment. The circuit board designs were originally drafted in black on a white background, then photographed and reduced to 1/4 their original size, and the film used as the stencil for the silkscreen.

Holes are drilled mostly by hand(!) in this clip, which is an error-prone process, as you can see from the Usagi Electrics guy. The worker uses what's called a pantograph drill. A pantograph is a device that translates motion from one place to another, often with a change in scale. Typically pantographs are mechanical in nature, based on the complimentary motion of opposite corners of a parallelogram, but you could make a pretty good argument that modern systems that accept movement inputs from a user and translate them elsewhere by computer are also members of the class. Robot-assisted surgery comes to mind. If you cared to have an even longer argument, you could also consider systems that scan items with laser photons in order to reproduce them on a lathe or CNC machine pantographs in spirit, if not in fact. 

A visual or optical comparator is just a device that projects a magnified view of something up on a screen, along with a point, grid, or profile it needs to match, not unlike a microfiche viewer with a targeting reticule. They're still used in some areas, although software image processing is steadily gaining ground. 

You'd be amazed at how many things still need a look-over by a human with a brain. The lack of human brains is how we got the sharply-angled board traces we have today, in fact. Computer-aided drafting was developed to a usable level in the 1980s, and predictably the people using it were mostly engineers. The kind of route-finding you do in those connect-the-dots puzzles, and that the electronics engineers did when drafting the boards, is one of those very slippery human things. You want to find the shortest path, to save on the precious metals you use as conductors, but the absolute shortest path (with reasonable tolerances) is often a very snaky curve that would require a large number of points to define. It's much simpler to work on a grid, hence the 45° and 90° angles -- this ensures that all trace paths can be defined exclusively by where their corners lie on a square coordinate system, and is much less calculation-intensive. This was a lot of what early graphics tablets (or digitizers) were used for, and some light pen systems. 

Having watched my father do a lot of this as a kid, I gather that at least in modern CAD software, you can just pick things up and put them wherever you want, but that the autopathing gets very confused if you do it too much -- mostly it's better to let the computer figure out where the traces go and tell you if you want something impossible in 3D space. And if you screw up anyway, there's always blue wire.

Circuit boards don't have to be the ubiquitous green, either. That's just the color of the solder mask, a lacquer painted all over the parts of the board you don't want solder to stick to. It's mostly tradition at this point, but you can get boards in pretty much any color you like -- the second most common I've see is a dark navy blue, probably because copper traces and white silkscreening stand out best on those two colors. You're welcome to get neon purple, if you can find anyone offering it.

The Power of Blue Light Therapy for Acne: Shedding Light on Clearer Skin

Acne, a common skin condition that affects millions of people worldwide, can be a source of frustration and self-consciousness. However, there is a ray of hope in the form of blue light therapy. This post will let you understand benefits, mechanisms, and effectiveness of blue light therapy for acne. 

Understanding Acne

Acne is a dermatological condition characterized by clogged pores, inflammation, and the presence of blemishes such as pimples, blackheads, and whiteheads. Excess production of sebum, hormonal imbalances, or bacterial overgrowth often causes it. While there are various treatment options available, blue light therapy has emerged as a promising and non-invasive solution.

How Does Blue Light Therapy Work?

Blue light therapy utilizes a specific wavelength of light, typically in the range of 405-420 nanometers, to target the bacteria responsible for acne breakouts: Propionibacterium acnes. When the blue light comes into contact with the bacteria, it triggers a photochemical reaction that produces singlet oxygen, effectively killing the bacteria. Additionally, blue light therapy helps reduce sebum production and inflammation, further aiding in the treatment of acne.

Effectiveness and Benefits

Numerous studies have demonstrated the efficacy of blue light therapy in reducing acne lesions and improving overall skin condition. It is considered a safe and gentle treatment option, particularly suitable for individuals with sensitive skin who may not tolerate other acne treatments well. Blue light therapy is non-invasive, painless, and does not require the use of harsh chemicals or medications.

Furthermore, blue light therapy offers several additional benefits. It does not damage the surrounding healthy skin, making it an ideal choice for targeting specific areas. The treatment is also convenient, with sessions typically lasting only a few minutes, allowing individuals to easily incorporate it into their daily skincare routine. Unlike some oral medications or topical creams, best light therapy acne treatment device has no significant side effects, making it suitable for long-term use.

Blue light therapy presents a breakthrough in acne treatment, providing a safe, effective, and non-invasive option for individuals struggling with this skin condition. By harnessing the power of specific wavelengths, blue light therapy targets acne-causing bacteria and reduces inflammation, leading to clearer and healthier skin. Consider discussing this option with a dermatologist to embark on your journey to blemish-free skin.

What Are The Functions Of Different Colors Of Light In LED Phototherapy?

Article source: https://www.litonlaser.com/functions-of-different-color-lights-of-led-phototherapy-machine/

1. Overview of LED PDT phototherapy beauty machine technology.

The basic principle of LED phototherapy PDT beauty machine is based on the living cells of organisms, which absorb light energy of specific wavelengths, and under the influence of light energy, increase reactive oxygen, activate mitochondrial reactions, produce adenosine triphosphate (ATP), stimulate fibroblast proliferation and secretion, promote lymphatic circulation, and produce biological reactions such as anti-inflammation, skin repair, and regeneration. Low-energy phototherapy can be equivalent to the “photosynthesis” of plants. This is a physiological reaction at the cellular and molecular level, which is called photomodulation biological action.

PDT skin rejuvenation is also called photodynamic skin rejuvenation or photodynamic therapy, collectively referred to as LED phototherapy. Under normal circumstances, LED phototherapy beauty machines will carry different colors of light, and each light reaches a different depth of the skin, so it has different functions and plays a different role in the beauty industry.

2. The main influencing factors of LED photodynamic therapy equipment.

2.1 Wavelength (color of light).

Different wavelengths correspond to different biological photomodulation reactions and results. Only reasonable wavelengths can be absorbed by the corresponding target color base to produce effects. In LED photodynamic therapy, wavelength is the most important treatment parameter.

2.2 Irradiation intensity (energy or power density).

Sufficient energy can stimulate the target organ to produce effects. Too low light energy has basically no therapeutic effect, so many beauty salons that choose home LED therapeutic devices say that the effect is not good, that is because the energy is too low.

2.3 The location depth and wavelength of the target tissue.

In a certain range, the shorter the wavelength (close to purple light), the shallower the penetration depth, and the more obvious the photochemical effect on the skin; the longer the wavelength (red light, near-infrared light), the deeper the penetration depth of the skin, achieving specific effects such as stimulating blood vessels, stem cell proliferation, collagen fiber regeneration, etc.

2.4 Effects on surrounding tissue cells.

After being illuminated by LED light, cells will release some biological signals, which will be transmitted to deeper dermal tissues to regulate cell functions, promote cell proliferation, and repair damaged cells.

3. Common color wavelengths and functions of LED photodynamic machines.

3.1 Red light: repair, anti-inflammatory, anti-aging, hair growth.

Red light (635-700nm, commonly used to 650nm), with a penetration depth of about 5-8mm, stimulates blood circulation, reduces inflammation, promotes wound healing, and promotes hair regeneration.

After visible light to near-infrared LED light penetrates the epidermis of the skin and reaches the dermis of the skin, it promotes the regeneration and rearrangement of elastic fibers and collagen fibers through photothermal and photochemical effects, thereby reducing skin wrinkles, increasing elasticity, uniform pigmentation, skin rejuvenation and mild wrinkle removal.

635nm LED light can inhibit the release of inflammatory mediators – prostaglandin E2 (PGE2) by gingival fibroblasts, thereby reducing the inflammatory response of the gums. Red light has a certain analgesic effect and can be used for anti-inflammatory and repair after laser treatment.

Red light between 630-670nm can promote hair follicle proliferation, delay the transition of the hair cycle from the growth phase to the regression phase, promote hair regeneration, and prevent continued hair loss.

3.2 Blue light: Treat acne and kill bacteria.

Blue light can treat acne and has bactericidal and anti-inflammatory effects. Its skin penetration depth is the shallowest. The spectrum of blue light is very consistent with the maximum absorption peak of Propionibacterium acnes (Propionibacterium acnes itself can produce endogenous porphyrins, the main components of which are coproporphyrin and protoporphyrin IX).

Using it to irradiate Propionibacterium acnes will cause photoexcitation of endogenous porphyrins in cells, produce singlet oxygen, and achieve a bactericidal effect: Propionibacterium acnes is an anaerobic bacterium. At the same time, blue light can change the intracellular pH value by inducing membrane permeation and inhibit the proliferation of Propionibacterium acnes.

The light source range for treating acne is generally within the range of 420-480nm. The blue light wavelength commonly used by yellow people is recommended to be 450-470nm, which is not easy to cause pigmentation and skin burns, and the deeper the penetration depth, the more significant the effect.

In the process of irradiating blue light to treat acne, attention should be paid to moisturizing and anti-oxidation. The time should not be too long. After treatment, sun protection must be used to avoid the problem of “acne is cured, but the face is darkened”.

3.3 Yellow-orange light: enhance immunity and desensitization, and have a convergence on vascular dilation

570-600nm yellow-orange light, the deeper the skin penetration depth is 2mm or deeper, it can stimulate collagen regeneration and whiten the skin.

Yellow-orange light irradiation can enhance immune function, reduce inflammation, calm, soothe sensitive skin and contraction, treat fine red blood streaks, rosacea; yellow light can also help promote skin repair after laser treatment, hormone-induced dermatitis, etc.

It can also promote collagen synthesis, treat capillary dilation and balance the overall skin texture, and mildly anti-aging. 580nm is the most commonly used wavelength, which can enhance repair and desensitization after laser surgery.

3.4 Green light: evens out skin tone, inhibits pigmentation, and relieves sensitivity

The wavelength is around 510-550nm. According to research, it can effectively stimulate mitochondria in cells and produce a series of effects such as stimulating cell activity, regeneration, repair, and anti-inflammatory.

Green light can slowly shrink dilated capillaries, has a slight anti-inflammatory effect, and can promote the body to produce serotonin, which is a quiet, euphoric hormone that relaxes and soothes people, slowly lowers blood pressure, and relieves certain neuropathic pain, such as migraine.

It also has the effect of gradually brightening the skin tone, which can help fade dark circles, and is more suitable for people with light skin. Dark skin types above type III can use orange LEDs with longer wavelengths.

3.5 Near infrared light.

Near infrared light (wavelength 800-900nm, some can reach 1200nm), with a penetration depth of about 10-20mm, can effectively fight inflammation, relieve pain, stimulate collagen proliferation and ATP production, so it can promote the growth of epithelial cells after trauma, promote the healing of wounds such as burns and scalds, and promote the repair of eczema dermatitis.

Near infrared light has been used to stimulate stem cell proliferation and differentiation. It can promote microcirculation and has a good therapeutic effect on the healing of chronic ulcers of the lower limbs for diabetic patients.

Equipment in the range of 580-850 has a certain effect on skin collagen stimulation growth, skin rejuvenation and pore shrinkage. This LED irradiation can make muscle and skin cells grow at 3-5 times the normal speed.

4. More information on LEDPDT phototherapy machines.

4.1 5-color LED phototherapy device and 7-color LED phototherapy machine.

In addition to the five-color LED phototherapy equipment of red, blue, green, yellow, and near-infrared light mentioned above, LITONLASER also has purple and orange light as supplementary light sources, which is the 7-color LED phototherapy device that is popular recently.

We now know that different colors of light have different functions. For PDT equipment, power is also an important factor, and what affects the power or energy of the machine is the power and radiation intensity of each lamp bead of the LED phototherapy instrument. As an old manufacturer with 20 years of experience, LITONLASER has fully studied LED machines. Our radiation intensity and the power of each lamp bead are the top in the industry. A machine has enough energy and the energy is sufficient and stable, so that it can bring obvious treatment effects!

4.2 Photoelectric beauty projects of LED photodynamic equipment combined with other machines.

In addition to being able to improve skin when used alone, LED phototherapy equipment is usually combined with other beauty machines to carry out photoelectric beauty projects, such as 560nm handle IPL beauty machine + blue light LED phototherapy for acne removal and skin rejuvenation projects; 1927nm fractional thulium laser + 650nm red light LED phototherapy machine for hair regeneration and hair loss prevention projects; CO2 fractional laser + red light LED photodynamic for scar removal and skin healing promotion projects, etc.

In fact, many machines can be used with PDT for project cooperation. If you want to know more about photoelectric projects and specific treatment details, or are interested in the machine, you can contact our website at any time: https://www.litonlaser.com/.

Pain Management Devices Seeing Rapid Growth in Healthcare

Low-level laser therapy (LLLT) or photo bio modulation therapy is a form of medical treatment that uses low-level lasers or light-emitting diodes to treat various medical conditions. These lasers are classified as Class IIIb or Class IV lasers and are used at higher doses than Class IIIa lasers that are used for diagnostic purposes. The theory behind LLLT is that the application of non-thermal laser energy can stimulate or inhibit natural processes in the body to reduce pain and inflammation through photochemical means. Several clinical trials have found LLLT to be effective at reducing pain from rheumatoid arthritis, tendinitis, carpal tunnel syndrome, neck pain, back pain, and other conditions. The wavelengths of light used in LLLT devices, usually in the red or near-infrared range of 600–1,100 nm, penetrate the skin and stimulate cellular activity at the mitochondrial level. This leads to an analgesic effect, increased blood flow, reduction of edema, and accelerated cellular metabolism. LLLT devices are very easy to use and typically involve passing the hand-held laser wand over the affected area for a prescribed number of minutes. The treatment is completely painless and has no known side effects. Transcutaneous Electrical Nerve Stimulation Devices Transcutaneous electrical nerve stimulation (TENS) devices are non-invasive electrical stimulators used to manage both acute and chronic pain. These devices deliver controlled electric pulses to nerve fibers under the skin surface for pain relief. The electric pulses override pain signals being sent to the brain, preventing the pain sensation. TENS devices are easy to use and often come with adhesive electrodes that the user places over the painful area. Settings like pulse duration, frequency and intensity can be adjusted as needed for different levels of pain relief. TENS therapy is commonly used to treat back pain, arthritis, labor pain, sports injuries and post-surgical pain. Clinical studies have shown TENS to be effective at providing pain relief for a variety of painful conditions without any serious side effects. Portable TENS units allow patients to self-administer therapy at home or on the go as needed. Spinal Cord Stimulation Pain Management Devices Spinal cord stimulation (SCS) therapy involves the surgical implantation of a neurostimulation device that sends electrical pulses to the spinal cord to block pain signals from reaching the brain. The device consists of thin electrodes that are implanted near the spinal cord and connected to a pulse generator similar to a pacemaker implanted under the skin near the buttocks or abdomen. The electrodes are able to modulate the transmission of pain signals that ascend from the peripheral nerves to the brain stem and thalamus. SCS is most commonly used to treat chronic back and leg pain caused by failed back surgery, complex regional pain syndrome, peripheral vascular disease or peripheral neuropathy. Clinical studies have found SCS to be an effective treatment option for managing chronic pain when more conservative therapies have provided inadequate relief. Complications of SCS device implantation are generally minor and reversible.

Week 6: Sustainability in Madrid Pt. 1

Welcome back! Somehow only 2 weeks of the program remain. How that is possible I am not sure. Time moves differently here. 

This week I thought I would talk about sustainability in the city. Sustainability has always been a passion of mine, and I have taken it upon myself – this past year especially – to live minimalistically so that I reduce the impact I have on the environment. This is especially important to me when I travel, as I don’t want to impede on the planet or people living in Madrid. Let me preface this post by saying that I am by no means perfect when it comes to this. It is a learning experience and gradual development that is a continuous journey I choose to partake in. On a less serious note, I hope you learn something new in this post!

Before coming to Madrid, I was excited to see what the city was doing to counteract climate change and get an understanding of the sustainability culture. The EU, after all, has been paving the way for sustainable development. After living here for six weeks, I think Madrid is doing above average -- pretty well -- overall. They mandate recycling, have incredible public transportation – including electric buses throughout the city to reduce photochemical smog – incorporate incredible green spaces, and have also managed to restore the Manzanares River. This is just to name a few. 

I particularly love all of the parks, greenery, and trees that have been integrated into the city. It is beautiful, cohesive with the architecture, has a calming effect – supported by research and is true on a biological level – cleans the air of toxins, provides shade, and helps to regulate temperatures, which creates a cooling effect. Also, despite being a metropolitan city, just an hour's bus ride away is a national park and even closer is Casa de Campo, a large park with mountain biking and hiking trails. All of these amazing services and parks that the city has to offer are truly something to be grateful for. Without the greenery and attention to nature, I'm not sure I would be able to live in the city quite frankly. Being able to coexist with nature is something that I've learned is of high importance to me.

In most parts of the city -- even on the busier streets -- I can find a variety of beautiful greenery. Many businesses will use decorative plants as well.

The reason I mentioned that Madrid is doing pretty well and not great is because there is one particular piece of the puzzle missing that would take the city’s sustainable development to the next level. The culture and environmental mindset in the city is not quite there yet. While they do educate children at a young age, I feel as though there is still an abundance of consumerism here (like the States) and lack of a circular economy. For those of you that may be unfamiliar with this term, it is a model of resource production and consumption in any economy that involves sharing, leasing, reusing, repairing, refurbishing, and recycling existing materials and products for as long as possible. It may seem intimidating, but there are plenty of ways and simple changes that you can make to your lifestyle with just a little planning and awareness!

Nonetheless, Madrid is heading in the right direction, and I hope it continues to tackle environmental issues and progress as a sustainable city. Come back next week for a part two on how I incorporate sustainability into my lifestyle and how to be environmentally friendly while traveling! Until next time :)
