GLOBAL WARMING

Global Warming is now a very bid deal. Do you know what Global Warming is? If you don't well I will explain it to you: Global warming refers to the rising average temperature of Earth's atmosphere and oceans and its projected continuation. In the last 100 years, Earth's average surface temperature increased by about 0.8 °C (1.4 °F) with about two thirds of the increase occurring over just the last three decades. Warming of the climate system is unequivocal, and scientists are more than 90% certain most of it is caused by increasing of greenhouse gases produced by human activities such as deforestation and burning fossil fuels. (Definition was used from http://en.wikipedia.org/wiki/Global_warming read this and tells me what you think about this)

Many people contribute to this without even noticing for example leaving your car (that uses gas) on for ten minutes so it warms up, using lots of aerosol spray(If you don't know how this creates Global Warming it's because the chemicals in the cans are very powerful and it can penetrate through our atmosphere. In this case this will make the atmosphere thinner and increase the temperature  of the Earth), cars are a big contribution to Global Warming (Vehicles such as cars are a big reason why there is Global Warming, many cars use gas, so lots of pollution come from cars. To be exact cars that run on gas create air pollution which makes Global Warming even faster. Here are couple of ways to be more Eco-friendly, carpooling is a great way to save gas. Take turns with the person you ride on carpooling. You can take the bus because it is a big vehicle but it takes more people to more places. Another way is to ride a bike, walk, Rollerblade, etc. There are more ways but here are a few of them.).

Global Warming has more then one impact other than the increase of Earth's temperature, but the possible extinction of the polar bear this is a very big deal. These poor animals are having a hard time living ever since Global Warming got worse. They are having a harder time trying to live since icebergs are melting. Global Warming makes it harder for the Polar Bear to hunt or travel. It takes more energy for them since it is getting hotter. Polar bears fur is made to swim in cold water and live in cold weather. It keeps the body warmth in and blocks off any cold air from entering the body of the Polar bear. We need to lower the percentage of how much we pollute the Earth so Global Warming doesn't kill the polar bear. I am not saying we can stop all of it but lower it.
