In recent years, climate change and global warming have been pressing issues, sparking many debates on how to best combat it. Increasing temperatures, rising oceans, and air pollution all pose a threat to the future habitability of our planet. One of the primary reasons for these issues are our overuse of fossil fuels and their resulting emissions of carbon and other harmful chemicals. As a result of human industrial activity, the rate of growth of carbon dioxide in the atmosphere has increased from 0.6 parts per million (ppm) in the 1960s to about 2.3 ppm in the past decade. As a result of the increased amount of this greenhouse gas in the air, more heat is trapped in the Earth and unable to escape, leading to temperature increases and other dangerous climate effects To reduce our emissions of carbon and other chemicals into the air, we must transition away from burning fossil fuels for energy, and move towards cleaner energy sources, such as solar, wind, and hydro power. These energy forms produce much less waste than fossil fuels, but need to be implemented on a large scale basis for a consistent noticeable decrease in chemical emissions.
As an effect of the coronavirus, many people have been quarantined in their homes and suspended from non-essential work. This has led to a large decrease of cars on the road, and less manufacturing plants burning through massive amounts of coal. As a result, carbon emissions have decreased globally, for example with China’s emissions cut by 25% at one point during their lockdown. Many large cities that have been consistently plagued with air pollution problems, such as Los Angeles, Seoul, and Delhi, have had about a 50% reduction in air pollution. From just the past few months of lower levels of carbon emissions, we are already able to see tangible environmental benefits as a result.
Although we are seeing some benefits as a result of decreased emissions for now, once lockdowns are lifted the world will simply revert back to the same usage level of fossil fuels from before the coronavirus. Because of this, we need to take efforts to shift to cleaner energy forms now, while we are in a downtime of fossil fuel usage. Due to the current quarantines, however, it would be difficult to physically replace energy systems with renewable sources, so I would propose that governments and companies take action to prepare the framework for the shift. For example, they should research what clean energy source would be most suitable based on the environment around their manufacturing/office locations. In addition, power utilities companies, such as heating and electricity, should also be examining how to best reduce their usage of fossil fuels. Simply exploring ways to reduce carbon emissions and how to use cleaner energy forms would be a great step forward towards actually implementing these solutions for a greener future.
Climate change and the environmental issues that it brings are something that we need to take action against. If we live our levels of fossil fuel usage untouched, the situation will spiral out of control to a point where we will be unable to stop the issue. Because of this, we must take advantage of the current reduced emissions as a result of quarantines to start the process of transitioning towards cleaner energy forms, that have much less harmful environmental impacts than fossil fuels.
