Our planet is getting warmer and warmer as years pass by. There can be two kinds of causes for this phenomenon. Global warming can be the result of man-made causes or natural causes which are created by nature.
A major natural cause for global warming is the release of methane gas from the Arctic tundra and wetlands. These gases can trap heat in the atmosphere. Another important natural cause is Earth’s normal inclination for auto-generated climate change. The earth goes through a cycle of climate change, which usually lasts about 40,000 years.
However, man-made causes, probably, do the most damage. Pollution is one of the biggest man-made problems. Burning fossil fuels is an important cause of pollution. The increased rate of deforestation also contributes to global warming.
The steady increase in population leads to the heating up of the globe. More people means more food, and more methods of transportation increases the use of fossil fuels, and thus, pollution. Animals like cows emit a lot of methane in the air, while many fertilisers also increase the amount of nitrous oxides in the air.
