__**Climate Change Affects Natural Systems**__ “How Climate Change Affects Natural System?” Well, there are a lot of reason why its affecting our natural system. Mostly because of what we do every single-day and the climate changing upon our Earth. For Example :
 * Several Ice Ages have occurred in the past.
 * Global Warming refers to a global increase in average temperature and etc.

The other information that “Climate Change Affects Natural Systems” is **__Greenhouse Gasses.__**

Greenhouse Gasses are gases in an atmosphere that Absorb and Emit radiation within the thermal infrared range. This process is causes by the Greenhouse Effects. The Greenhouse Gases include, Water Vapor, Carbon Dioxides, Methane, Nitrous Oxide and Ozone. Greenhouse Gases Affect the temperature of the Earth. Without them, the Earth Surface would be on average about 33 °C (59 °F) colder than at present. The Industrial Revolution of Fossil Fuels and Deforestation has increase the level of carbon dioxide in the atmosphere. //***Diagram of Greenhouse Effect**//

Methane is very efficient at trapping thermal energy, 25 times more efficient than Carbon Oxide produced by bacteria breaking down wastes in oxygen, free environments and digestion//**.**//




 * Nitrous Oxide is the Bacteria,Fertilizers and improper disposal of human and animal waste.is
 * Ozone Layers is important because its the Ultraviolet Radiation Blocker in the stratosphere.

=Project 2: Unit 1 Final Project= = = =* __Oil Spill__= An oil spill is the release of a liquid petroleum hydrocarbon into the environment due to human activity, and its a form of pollution. The oil may be a variety of materials, including crude oil, refined petroleum products such as gasoline or diesel fuel or oil mixed in waste. Spills may take months or even years to clean up. Oil also enters the marine environment from natural oil seeps. Most human made oil pollution comes from land based activity, but public attention and regulation has tended to focus most sharply on sea going oil tankers. The Gulf of Mexico Oil Spill was one of the largest Marine Spill in the world history.

During Oil Spill many things are Affected. The major one's are **//__Abiotic__//** ( relating to non-living parts of an environment such as sunlight, soil, moisture and temperature) and **//__Biotic__//** (relating to living organisms such as plants, animals, fungi and bacteria). For example the birds on the ocean, the oil penetrates up the structure of the plumage of birds, reducing its ability, and so making the birds more vulnerable to temperature fluctuations and much less buoyant in the water. Also its hard for them to escape from the predators because of that oil covering their feathers which causing them kidney damage, altered liver fraction and digestive tracts irritation. Also since the oil floats on top of the water, less sunlight penetrates into the water, limiting the photosynthesis of marine plants and phytoplankton. This, as well affects the food chain in the ecosystem because when small fish eat the plankton, they also eat the oil. Bigger fish, bears and humans who eat these fish will ingest oil too this is showing that it could also damage the food web.
 * __Oil Spill Affected the Environment__**

Also the Oil Spill could affect the Carbon Cycle because some of the carbon are stored in plants in the oceans and marine animals. The plants wouldnt grow because of the toxic fume from the oil spill and the animals might eat this plants, which could lead to there death.
