Climate change may be one of the biggest threats facing the planet. The climate is changing and the earth is warming up. With global warming on the increase and species and their habitats on the decrease, chances for ecosystems to adapt naturally are very small. Natural events and human activities are believed to be contributing to an increase in average global temperatures. But primarily increased by greenhouse effect. If the greenhouse effect becomes stronger than what it already is, more heat will get trapped than needed and the earth might be less habitable for humans, plants and animals. Human activity has caused an imbalance in the natural cycle of the green house effect. When we mine, coal and extract oil from the Earth's crust, and the burn of fossil fuels for transportation, heating, cooking, electricity and manufacturing, we are effectively moving carbon more rapidly into the atmosphere than it is being naturally removed. Also, by clearing forests to support agriculture, we are transferring carbon from living biomass into the atmosphere. Humans are adding ever-increasing amounts of extra carbon dioxide into the atmosphere.

Nutrient Pollution is one of America's most widespread, expensive and challenging environmental problems. Nutrient Pollution is caused when there is excess nitrogen and phosphorus in the water and air. Nitrogen and phosphorus are a key element to the growth of algae and aquatic plants, which provide food and habitat for fish. When there is too much nitrogen and phosphorus in the water it causes algae to grow at a rapid rate, and lots of algae, leads to harmful water quality, food resources and reduces oxygen. There is Nutrient pollution in ground water as well, which numerous amounts of people in the United States use as their drinking water. United States Environmental Protection Agency recently posted an article "The Problem" stating that " Excess nitrogen in the atmosphere can produce pollutants such as ammonia and ozone, which can impair our ability to breathe, limit visibility and alter plant growth". Also, when excess nitrogen returns to earth from the atmosphere, it can harm health of forests, soils and waterways. Nutrient Pollution is a huge issue in America that people are not aware of. |
