What is GLOBAL WARMING

The horror of Global Warming

Before
After


Global warming is one of the most serious challenges our planet faces. Left unchecked, it will increase the severity of hurricanes, cause major flooding, and intensify desertification. Global warming is the direct result of adding too much carbon dioxide to the atmosphere. The average American releases about 20 tons of carbon dioxide to the atmosphere each year through daily activities like driving to work, turning on lights, and heating and cooling the home.

Carbon Cycle

The Carbon Cycle is a complex series of processes through which all of the carbon atoms in existence rotate. The same carbon atoms in your body today have been used in countless other molecules since time began. The wood burned just a few decades ago could have produced carbon dioxide which through photosynthesis became part of a plant. When you eat that plant, the same carbon from the wood which was burnt can become part of you. The carbon cycle is the great natural recycler of carbon atoms. Unfortunately, the extent of its importance is rarely stressed enough. Without the proper functioning of the carbon cycle, every aspect of life could be changed dramatically.
