Here are some examples of where man has changed the face of the globe. It’s called manmade change, or anthropogenic change. There is no doubt that this was done by man.
The picture below shows the Neza Chalco Itza slum with its epic 4 million inhabitants. It is the world’s largest slum and has the highest crime rate in Mexico.
I know this is anecdotal and not very scientific, but given these visible examples of what humanity has done to the planet, do we really want to believe that we didn’t modify our air just as drastically? Too bad we can’t see the CO2, and what it does to the planet. We’ll just have to wait a hundred years when our grandchildren won’t be able to walk in lower Manhattan or when most of coastal Florida will be under water. Let’s not even talk about New Orleans.
