What cause global warming?
1)Natural Causes
They are causes that are created by nature. An example is a release of methane gas from arctic tundra and wetlands. Methane is a greenhouse gas and a very dangerous gas to our environment. A greenhouse gas is a gas that traps heat in the earth's atmosphere. Another natural cause is that the earth goes through a cycle of climate change. This climate change usually lasts about 40,000 years.
2)Man-made Causes
These do the most damage to our planet. Pollution is one of the biggest man-made problems. An example is burning of fossil fuels. Fossil fuels are fuels made of organic matter such as coal or oil. When they are burned, they give off a green house gas called CO2.
Another major man-made cause of Global Warming is population. More people means more food, and more methods of transportation. That means more methane because there will be more burning of fossil fuels and more agriculture. Another source of methane is manure because more food is needed to feed the population we have to raise food. Animals like cows are a source of food which means more manure and hence more methane. Another problem with the increasing population is transportation. More people means more cars which cause more pollution.
Since CO2 contributes to global warming, the increase in population makes the problem worse because we breathe out CO2. Also, the trees that convert our CO2 to oxygen are being cut down because we're using the land that we cut the trees down from as property for our homes and buildings. We are not replacing the trees (trees are a very important part of our eco-system), so we are constantly taking advantage of our natural resources and giving nothing back in return.
As population increases, more pollution will be produced.
This will cause air pollution and living things will have no fresh air to breathe.
