The Earth's Major systems all interact with one another. The hydrosphere requires the atmospheres assistance in storing and moving water through it's cycle. The biosphere then requires this water for sustaining a healthy ecology for the planet. The geosphere pumps greenhouse gases into the atmosphere through volcanic activity which then can alter the behavior of the hydrosphere's water cycle. The geosphere also helps in the runoff of water, the discharge of water into the sea, and can also have an effect on weather patterns. Without a stable interaction between these 4 systems, each can be effected. For example, if the hydrosphere is greatly altered by any means, drought and hunger can ravage the biospheres sustainability, and many numbers could die or migrate.
Human activity also has an effect on every Earth system. Pollution is already generating a problem for life, since it is contaminating ecosystems making very difficult for some species to live. Deforestation and many other activities are speeding up a shift in the hydrosphere, which in turn can alter the normal climate.
All related information is relevant to our understanding of both our impact and how we can lessen it, and the spirit of exploration. Some of our religouse or finatical organizations may disagree, however this cannot change anything. Some dissagreeing theorists have stated that this is normal behavior for the Earth's environment. Most of the scientific community agrees with the fact that our impact is going to be greatly felt.

C02 (carbon dioxide) is one of these gases that is the leading culprit in storing heat. Carbon Flux before the industrial revolution stayed a steady 0 x 10^12. By about 1870-2000 the amount of C02 emissions jumped from 0 to about 6.5 x 10^12 (that equals 6,500,000,000,000) in kg of carbon dioxide gas. This was measured in the atmosphere and ice cores drilled in the Antarctic. The cause of this jump is the burning of fossil fuels such as oil (gasoline), and coal. Since the creation of automobiles the amount of C02 gas in the atmosphere has risen 100 parts per million. That might not seem like a reasonable ratio, 370/1,000,000, But it is alot for our atmosphere. This means that along with water vapor our chances for Global Warming Potential are great.
