The earth went through a lot. And I mean a LOT. But nothing tops the how the 20th and 21st centuries impacted the Earth in a negative way. From the Spanish Flu to the two World Wars, and countless deaths, we can agree that the death count of the 20th and 21st centuries was a massive one and greater than any other generation of the world. With all this, a new pandemic comes along and now ruins the world even more. It's sad.
