I am Hilary Canary and I am a student at Carl Sandburg Middle School. I believe that global warming is caused by humans and needs to be stopped. I don't think that humans should have expected that our years of excessive fossil fuel emissions would amount to nothing. But what¢s done is done, and now we need to work on ways to fight global warming. There are so many easy ways to help to slow this vicious process that people need to grow accustomed to doing. Such as taking public transportation, riding a bike, or joining a carpool instead of wasting gas. Or buying organic and locally grown foods. Also, try changing the light bulbs in your house to compact fluorescent bulbs. These are only a few easy ways to save the environment. You might be surprised at the big results that little changes can make.
