why dusts?

 I believe the problem stems from our over reliance on fossil fuels. During the last few decades, people have struggled to find ways in maximizing the use of renewable energy and decrease the usage of fossil fuels. Some scientists even suggested that nuclear energy could be the perfect answer to the undeniable needs of human resources. Because of those efforts, we actually found many solutions to this problem that are huge. However, we still aren't able to solve this issue. In Korea, we had to deal with fine dust problems befor the pandemic. Even though everything is okay these days, we still haven't found the right answer to this conundrum.
