We have created a hole in the ozone bigger than Antarctica. We have created a garbage patch in the Pacific Ocean the size of Texas. At the current rate of deforestation, we will have destroyed half the Amazon rain forest by 2060. We have almost doubled atmospheric CO2 in the last 200 years. Atmospheric CO2 is now at the highest level ever recorded, and the Antarctic ice core record goes back 600,000 years. We are changing the earth.
