What is photosynthesis?

Photosynthesis is process by which light energy is converted into chemical energy. Becasue of photosynthesis, the plants, some bacteria and protistans use the energy from sunlight to produce sugar, which cellular respiration converts into ATP (adenosine triphosphate), the “fuel” used by the all the living things. The conversion of unusable sunlight energy into useable chemical energy, is associated with the actions of the green pigment chlorophyll. Most of the time, photosynthesis process use water and release the oxygen that we absolutely must have to stay alive.

Global warming

Washington (ChattahBox) - A report released by the National Snow and Ice Data Center in Boulder, Colorado has revealed that the Arctic ice is at its second-lowest level in history, and is melting because of the impact of global warming.

The National Snow and Ice Data Center put out the report late last week, confirming that the Arctic sea ice is melting away.

It is at its second-lowest point in recorded history. The lowest-point in recorded history was in 2007.

The report stated that “We could very well be in that quick slide downward in terms of passing a tipping point.”

That tipping point has to do with global warming, and is causing major problems for the Arctic sea ice, and endangered species such as the polar bear.

The level of Artic sea ice in 2008 is at 2.03 million square miles, compared to 1.59 million square miles in 2007.
