Causes of Global Warming

I think that we are the reason behind Global Warming, people are trying to fulfill their needs without thinking about the damage that they’re causing to the earth. We need to keep our sights clear and understand that global warming is one of the biggest geological threats to human existence and try to stop it. There are many causes of Global Warming, I’ll mention some causes and I’ll pick one of them and talk about it.

1. Carbon Dioxide from Power Plants
2. Carbon Dioxide Emitted from Cars
3. Carbon Dioxide from Trucks
4. Carbon Dioxide from Airplanes
5. Carbon Dioxide from Buildings
6. Methane
7. Nitrous oxide
8. Deforestation
9. City Gridlock
10. Carbon in Atmosphere and Ocean

As you can see, I mentioned ten causes of Global Warming and I’m going to talk about the Carbon Dioxide Emitted from Cars.

About 20% of carbon dioxide emissions come from the burning of gasoline in cars engine and light trucks. The vehicles with poor gas mileage contribute the most to Global Warming, for example, the new Dodge sport vehicles with 5.9-liter engine, which gets 12 miles per gallon in the city, will emit huge amounts of carbon dioxide over a distance of 500 city miles. So as we all know that carbon dioxide has been rising since the invention of steam engines because they depends on burning coal, oil and natural gases to power them and these fuel resources are causing a huge amount of carbon dioxides which obviously cause Global Warming.
