We humans have drastically changed our earth:
- We move more rock than all the rivers and glaciers.
- We produce more heat than the earth itself.
- We are driving animals extinct faster than they died off when an asteroid terminated all the dinosaurs.
If we are going to make such drastic changes, we should know exactly what the effects will be, but we do not care in the least. This means humans are going to go extinct within a century or two, extinction by suicide.~ Roedy (1948-02-04 age:69)
