Is it not obvious? If humans did not exist, plants would eventually sequester enough carbon dioxide to turn the Earth into a frozen ball of ice, with no life of any kind.
Our job in the Great Scheme Of Things is to dig up million-year-old dead plants and animals and burn them , thus returning the carbon, and the CO 2, to the atmosphere. If we did not do this, all life on Earth would freeze to death.
At the Green Net conference in San Francisco, Microsoft’s chief environmental strategist, Rob Bernard, talks about how the company is examining climate change by studying carbon cycles and the massive amounts of carbon sequestered in the top layers of soils around the world. For example, in the Amazon, Microsoft scientists are deploying sensors on the forest floor, measuring the rate of decay and then gauging the impact on global warming.
