3. global warming GLOBAL WARMING Definition: Global warming is the observed increase in average temperature if the Earth’s atmosphere and oceans in recent decades. It is due to the increased amounts of greenhouse gasses like C02. Greenhouse gasses absorb the infrared rays that heat the planet, instead of allowing them to escape the atmosphere.

Increased gasses are a result of human population increase and inventions such as gas exhaust from cars. Increase in global temperature can result in the increase of sea level and amount of precipitation, in turn creating floods Increase in global temperature can result in the increase of sea level and amount of precipitation, in turn creating floods Other theories believe that global warming is within the natural cyclic fluctuations. We are just at a high point in temperature. Other theories believe that global warming is within the natural cyclic fluctuations. We are just at a high point in temperature.

Destabilizes the eco system as a whole, removing one species may remove a link to the food chain, other species who interact or depend on them may starve. Also, one species may become more rampart if not removed by another.

Possible contaminants could include organic and inorganic matter. Pollution sources range from surface runoff to industrial discharge. Possible contaminants could include organic and inorganic matter. Pollution sources range from surface runoff to industrial discharge. Water pollution kills fish and destroys plant life. It can also harm human beings, besides the fact that we are consumers of fish. Water pollution can eliminate valuable drinking water and can create sickness and even death.
