I've read that the incidence of asthma has been increasing in the population. And yet...back in the sixties when my kids were little, both of their parents were smokers. Their healthy little lungs were polluted with second-hand smoke on a daily basis. What kind of people would do that?! How could we have been so ignorant and selfish?
We humans seem to blunder our way around the planet doing insanely destructive things without any regard for the consequences. Then we have to struggle to repair the damage in a costly last ditch effort. We rarely succeed.
We really don't deserve this beautiful, incredible Earth. The single largest man-made structure on the planet? The answer is Fresh Kills, the rubbish dump on Staten Island, NY. It is close to 5 square miles in area and exceeds both the Great Wall of China and the pyramids in volume. It was closed for good after debris from the World Trade Center was deposited there in 2001.
Thankfully, they are now flattening and landscaping the area and plan to make it into a park.
I still wonder, though, will there ever be intelligent life on Earth?
