Unit 6 Soil Pollution

“The problem is the way we are thinking.

The problem is fundamentally a cultural problem.

It's at the level of our culture that this illness is happening.”

~ Thom Hartmann

Warm up

Soil pollution is particularly dangerous for the environment and our health because soil, either in the mountains or in the plains, contains the largest part of the water we drink and produces all the food we need.

  • What is soil pollution?
