As mankind? Think how many cars were there in South America, Africa or Asia 50-70 years ago. Its what now, 100x more?

Even in Europe its at least 10x but probably more compared to my childhood where I lived (east & west). My parents used to play as kids on the roads next to their places, those few cars per hour were slow and easy to spot and hear. Now its a car every few seconds at least.

We also found plenty more way to pollute and more types of materials to burn. Also all is now permeated with micro and nano plastics.
