The Greening of Planet Earth examines the role that CO2 plays as one of nature's basic building blocks of life in the process of photosynthesis and the evolution of the earth's biosphere.  Evidence is presented to show how current CO2 levels, which are 35 percent higher than in the pre-industrial era, have greatly enhanced the growth of trees and other plants.  Results from controlled studies show how a doubling of CO2 in the atmosphere, which is expected to occur over the next century, will boost crop yields, increase the water-use efficiency of much of earth's vegetation, and enhance the productivity of forests.  The impact and implications of such change are far-reaching.

The Greening of Planet Earth Continues
The controversy over the effects of increasing levels of carbon dioxide (CO2) on nature - and the burning of fossil fuels that contributes to it - continues to intensify.  Despite solid evidence to the contrary, many media reports speculate that increasing CO2 levels will result in apocalyptic global warming and eventual environmental disaster.

In The Greening of Planet Earth Continues, expert scientists assert that CO2 is not a pollutant, but a nutrient to life on earth.  The video further explores issues addressed in the first of this two-part series, The Greening of Planet Earth, which has been distributed to more than 30,000 people worldwide.

Learn the facts about climate history and the problems with computer simulations used to predict the impact of increasing CO2 levels.  Discover what increasing CO2 levels really mean - faster plant growth, greater agricultural yields and improved water-use efficiency in plants.  Evidence paints a picture of the ongoing industrial evolution of humankind as the greening of planet earth continues.
