Deforestation and the Consequences

Deforestation has become a serious problem in the past few decades. Forests around the world have been destroyed due to increased demands for lumber supply, as well as many other resources. Many people don’t know how important forests are to the ecosystem, however. Forests “help people thrive and survive by, for example, purifying water and air” as well as by “soaking up carbon dioxide” (worldwildlife.org). Recently, more attention has been placed on forests because of the raging wildfires that we saw in the Amazon rainforest as well as in Australia. It is essential that we maintain the integrity of our rainforests because it is the habitat for millions of animals, as well as a supplier of jobs for millions of people. Unfortunately “in the Amazon, around 17% of the forest has been lost in the last 50 years” (Worldwildlife.org). If this continues, a vital part of our ecosystem will be destroyed in the next centuries. When we talk about the huge amount of land that is being destroyed, many people have a difficult time visualizing exactly how much it is. To put it into perspective, “In 2019, the tropics lost close to 30 soccer fields’ worth of trees every single minute” (Worldwildlife.org). This is an incredibly large amount of land. By saving the forests, we are really saving ourselves. We need to put more emphasis on the conservation of resources and realize that although the earth is tenacious, we may do damage that is not reversible.

Metal+Glass Recycling in the USA

Using a similar set of statistics as some of my peers, I thought about the topic of sustainability, and so a question I asked myself is: what’s in my environment that I can potentially reuse. Two types of material I come to find I use often include: glass especially when I think of my phone, what I use to drink, windows etc. The second one I often use is metal whether that be my phone, my car, my speaker etc. From 1960-2018, the epa estimates that the total change in glass recycling amounted to approximately: 2,960,000 tons. In that same time stretch, total change in the amount of metal recycled amounted to 8,670,000 tons. The growth factor for glass was about 30.6 and for metal it was about 174.4. The Percentage Change for glass is then: 3060% and for metals it was 17440%. When calculating the rate of change for glass: 2.96 x 10^6/58= 51034.48 tons more of glass was recycled per year and for metals it was: 8.76 x 10^6/58= 151034.48 tons more of metal recycled per year. 

Glass recycling on the surface may sound like a good idea, but I decided to dig a little deeper into the materials recycling controversy surrounding its overall utility. According to various websites disputing the overall eco-friendliness of the material, glass is “endlessly” recyclable yet bottles/jars etc. require more energy to manufacture and then recycle and process into sand or reprocess into reusable glass than it takes to reuse plastic. However, plastics’ lifetime utility decreases after a few years whereas glass according to some websites is repeatedly reusable. According to one source, for 10% of broken down glass getting recycled (per year) total energy costs to break it down reduces by 3%. This controversy makes me reevaluate the short-term and long term impacts, in other words, the opportunity cost not just on the good itself, but the lifetime impact of the consumption of the good and its future ramifications on an interconnected issue like carbon emissions.

Europes goal climate neutrality

When I think of sustainability the first that comes to mind is carbon neutrality. “Carbon neutrality means having a balance between emitting carbon and absorbing carbon from the atmosphere in carbon sinks.”(European parliament).  I am addressing a company named European Green Deal by the European Commission which aims to make Europe climate neutral by 2050 by enforcing laws by the EU Legislations(European parliament). Data shows that the decay factor is 9.5-11 gt while the growth factor is 38 Gt. The percentage change is decreasing by  -.75(9.5-38/38) and -27/28(11-38/38). This decrease is due to the natural carbon sink because no unnatural carbon sinks are able to remove carbon from the atmosphere at a significant scale to fight global warming the co2 emission will increase. Nonetheless, the rate of change demonstrates the amount of co2 released in the atmosphere is 27 and 28.5 annually (27-28.5).

The Importance of Solar Panels

Solar panels are an extremely effective way to help combat greenhouse gas emissions by taking natural energy from the sun and converting that into electricity. Using solar panels decreases our dependance on fossil fuels, which as we have previously learned in important to reduce for sustainability purposes and the health of the earth. There are at least 92.7 billion solar panels in use throughout the world today. One year of solar power saves 12,500 pounds of carbon emissions, which is very important in the subject of sustainability. With less carbon emissions and using natural energy, there are less fossil fuels and therefore a more healthy planet.

The United States and other European countries, like Spain and Italy, and China are the driving forces in increasing the amount of solar panels used. These countries receive a lot of sunlight making this initiative to use solar panels very effective. It is predicted that the growth rate of solar panels will be 7.8% from 2022 to 2030.  The power generated from solar panels has grown by 23% since 2019, making this energy source account for 3.1% of global electricity. In America specifically, the amount of solar panels installed grew 485% from 2010 to 2013. The amount of solar panels that the U.S. had installed by 2014 was enough energy to power about 2.4 million U.S. households. According to the growth rate, solar panels are increasing around the world and saving this initiative from countries is helping to save energy globally.

Solar Worldwide

One method to the world becoming more sustainable is the use of solar energy. Solar power is a process of taking renewable energy from the sun and turning it into electricity or power run sources. A method of this is the use of solar panels on houses or buildings. These panels take in the sunlight and are able to turn the natural resource of the sun into electricity, which is cost saving and way more environmentally friendly. The amount of greenhouse gasses such as CO2 getting released into the atmosphere is substantially brought down from the use of solar energy. A way to explain how much improvement that solar panels are doing is to say that each car emits 4.7 metric tons of carbon dioxide every year. It is proven that a solar panel system can offset the emissions of one car per year. The amount of CO2 emissions by a single vehicle may not sound impactful, but just think if everyone was aware of the benefits of having solar panels, then thousands to millions equivalent of one car can be impactful through reducing greenhouse gasses into the atmosphere. This is basically saying that through solar energy, one car per year can be taken off the road theoretically, benefiting the environment hugely.
Through looking at the current exponential growth of solar energy and wind energy, both renewable sources, the market share grew, “at a compound average annual growth rate of 15% from 2015-2020. If exponential growth continued at this rate, solar and wind would reach 45% of electricity generation by 2030 and 100% by 2033.” If by 2030 there is 100% use of renewable sources of energy, then the environment and atmosphere would benefit through the lack of greenhouse gasses being emitted. With the rising awareness of how the atmosphere is effected through CO2, if more people can implement using solar or wind energy, not only would families have a ton of money on their electricity bills, but also will benefit the environment. How can anyone be against these two huge benefits?
