The Ozone Layer Is Still Declining

Back in 1985, scientist discovered that the Ozone layer was declining. The Ozone layer is about 10-50 kilometers above Earth's surface filled with gas that keeps people, plants, and animals safe from the sun's harmful ultraviolet waves. The ozone layer is scattered between the upper, middle, and lower stratosphere as well as the troposphere. Throughout the layers, the middle and upper layers have rebounded since 1985 when the problem was first spotted. As for the lower layer, it has continued to drop since 1985! Although the drop is not as fast as it was in 1985, it is still happening.
There are multiple reasons why the ozone layer is still declining but none of their reasons can be scientifically proven. Other experts are impressed by the studies but are worried about what they found. In 1985, the rate of decline was five percent and now it has decreased to only 0.5 percent. 
Why are experts still worried about the decline of our ozone layer? If we keep this up, there will no longer be an ozone layer and you know means... no more us. Most people believe since the decline is so slow, the issue does not matter anymore but, that is not the case. William Ball, a scientist who is researcher studying the decline of the ozone layer states,"We should be worried. We need to urgently sort this out because we don't want the ozone layer to get worse"(Sneed). When you research something and take action to change it, you have to make sure that the change is happening.

    Why do we need protection from ultraviolet rays? Are there other methods of protection besides the ozone layer?

Deforestation+Animal Killing=The Near Death of a Species

If we do the math for Science Daily's article named, " In 16 years, Borneo lost more than 100,000 orangutans ",  Borneo has lost more than 6,000 orangutans every year, meaning about 17 orangutans die every day. The World Wildlife Fund estimates the current population of Bornean Orangutans to be about only 104,700 individuals, making a loss of more than 100,000 devastating for the population. And as the study in which this article takes its data from took place from 1999 to 2015, meaning that now, in 2018, this number could be much higher. The main cause of this loss was from the destruction of their natural habitat, the rainforest, in favor of palm oil, wood, and wood-based products. Using the age old strategy of "Saying No with your Wallet" sounds like a good idea to stop this, but the area that had the greatest loss of Bornean Orangutans were not these deforested areas, but rather areas where logging restrictions were already in place to save the environment.

China becoming the World's Largest Carbon Market

China, the largest global emitter of greenhouse gases contributing largely to global rising temperatures, is now trying to make progress toward decreasing this. Where they have begun an emissions trading system that for now covers gas and coal power production. That will include 11 different emissions baselines for plants based on whether power they run on, their size, and other factors.Having this cap on fossil fuels will allow them to take steps toward helping them with their smog epidemic.Other countries should also follow China in their effort to help remedy their emission output. China's plan is a little similar to the EPA's Clean Power Plan that is now planned to be made ineffective.Which could be detrimental to the environment by being able to output more greenhouse gases. In order to go forward, we need more acts put in place for cleaner power and more baseline on emissions that plants are able to put out. https://www.scientificamerican.com/article/china-set-to-debut
