"Bag It" Reflection 1

Today I watched a movie that is actually about "plastic bags". It tells about how much plastic is bad to us as well as our environment. Plastic bags will never be gone. It is made out of fossil fuels. This relates to Earth science.The topic that we learned about. Which is, energy sources. Energy sources contain Coal, petroleum, natural gas, and alternative energy. The biggest problem of the plastic it is pollution. I heard that 500 billion of plastic bags were made. It causes pollution to the air, water, etc. But it mostly pollutes ocean. The cause of the pollution from plastic made countries start to use paper bag or their own bag instead of plastic bag. So, nowadays many countries are banned to use plastic bags. Not only plastic bags, there are plastic bottles, aluminum can, plastic cups, etc. They were all used but thrown right away. I did not understand why people are making plastic if they are going to be thrown away in short time of period.(?) I think using paper bag is the best because it could be recycled over and over ( can be used a lot of time). However, also paper bag harms environment because to make paper bags they would have to cut down the trees. To sum up, it is relating what we learned and I would want everyone to recycle plastics. Then it will help our Earth to be GREEN.
