I step out the door and breather in the cool early morning air. The air is so fresh and it wakes me up almost immediately. Just then I hear a put put put as the next door neighbors car comes to life. The car passes me and the air around me clouds over and turns smoky. I cough and try to push the air away put I can feel it being absorbed into by lungs. Slowly but surely our cars are polluting the world. Killing animals, plants, and the air we breathe. We cannot let this happen. Did you know that greenhouse gases keep heat close to the earth’s surface making it livable for humans and animals? However, global warming is happening largely due to an over-emittance of these gases and fossil fuels (natural oil, gasoline, coal). We need to stop using so much gas, instead of powering our cars with cars and oil we need to power them using electricity. So start making a difference, carpool places take city buses and trains. Don’t use air conditioning, use fans. You can help!
