Global Warming:
Global warming is caused by two things, man made and natural causes. Man-made causes include pollution and burning fossil fuels which leads to pollution. Fossil fuels give off c02 when they’re burned, and co2 is a green house gas. Population is also a big factor, because the more people there are, the more transportation is needed, which means more pollution. We breath out c02, and trees take our co2 in, but since we’re cutting trees down and not replacing them, the co2 is being released and there are less trees to take it in.
The natural effects are arctic tundra and wetlands releasing methane. Since methane is a greenhouse gas, and it traps heat in the earth’s atmosphere. Also earth has about a climate change that usually lasts about 40,000 years.
If we replant trees after cutting them down we would have a lot less co2, and we would e helping save our planet. If people try to use as little transportation involving methane as possible, that would also help our planet. We are not only hurting ourselves, but we are hurting the cold climate areas, and are causing everything to melt. If people realized this, our planet would be much better.
