In this article, it is discussed how many different countries, other than America, are found to be incredible dangerous when it comes to littering and keep trash off of the streets and oceans. When people tend to think of Global Warming and littering issues, they tend to only think of what they can do in their own country, and for the most part, this seems to be talked about in America.
I think an important part of this process, if we as humans are really trying to make a difference on our environment, would be to educate other countries about the dangerous of littering as well. As shown in the chart taken from this article, other countries such as China and Indonesia are struggling immensely when it comes to trash issues.
I would argue that we are not actually making an impact on the environment as a whole if we do not take a step back and make sure we are educating the whole world, not just our country.
Carbon Dioxide (CO2) is a naturally occuring greenhouse gas that is a part of our atmosphere. The reliance on factories and various forms of transportation to burn fossil fuels have increased the amount of CO2 found in our atmosphere today. While, carbon dioxide only makes up 0.04% of the atmosphere this number has increased significantly overtime. Today CO2 levels consist of over 380 parts per million (ppm) but, prior to the Industrial Revolution carbon dioxide consisted of 270 ppm. Specifically, throughout this decade, CO2 levels have increased on average, 2.3ppm per year. Also, we emit 400 billion tons of carbon dioxide per year. In metric units this is 362.874 Tonnes. Again, this number simply shows that while CO2 makes up less than 1% of our atmosphere, the unnatural increase of CO2 has shown negative effects.
It is important that we find a way to reduce the amount of carbon dioxide in the atmosphere because it has serious effects on the environment such as making our oceans more acidic and increasing the temperature on earth. A New York Times article discusses the fact that removing Carbon Dioxide from the atmosphere is a potential way to stop global warming. The goal would be to keep the carbon dioxide below the two degree Celsius target estimated in 2015 by the Paris Agreement. However, this is an extremely difficult task. One suggestion would be to follow a process known as “direct air capture” to minimize its presence. All of the studies show that it is extremely hard to decrease the amount of CO2 currently in the atmosphere but it is crucial that we take conscious steps to reduce it for the future sake of our environment.
A current environmental issue that is facing us today is how to control the rising levels of CO2 in the environment. CO2 levels have been increasing at a record rate, with the levels raising to 400.83ppm in 2015. This was an increase of 3.03ppm from the previous year, making it the first year that CO2 raised by more than 3ppm. Now, as of yesterday, the current CO2 levels are 405.19ppm. There is clearly a need to be concerned about the future of CO2 levels and a need to determine ways to slow their rising levels and begin to decrease the levels over time.
One idea that has been considered by scientists comes from the knowledge that trees consume CO2 in order to grow and, in turn, remove some CO2 from the environment. Additionally, they emit much-needed oxygen into the environment. In order to test the theory that trees may suck up CO2 and make strides in cleaning the atmosphere, scientists created a model environment that aimed to replicate the high CO2 levels that are inevitable in our future. They sprayed 2 tons of pure carbon dioxide into the canopies of trees in a 500 square meter plot every day for 6 months. This created an atmosphere with about 530 ppm of CO2, which is about 150% of what exists today.
Unfortunately, their experiment did not yield the results they had hoped for. The CO2 did not enhance the growth of the trees and leaves, rather the CO2 quickly passed through the bodies of the trees and quickly returned to the atmosphere. There was no decline in CO2 in the atmosphere and the extra CO2 did nothing to help with the photosynthesis of the trees or their oxygen emissions. Unfortunately, this demonstrates a need for more research to be done as to how to reduce CO2 in the atmosphere.
