Since there are so many people living in NYC it can get really crowded and there are lots of cars and busses on the roads that emit fumes that are bad for the enviroment. You can tell because the air actually smells bad - like the exhaust from a truck. All the chemicals in the air are really bad for people and nature but New Yorkers are doing all that they are can do to help make the air quality better.
Many people who do their commute into work try to ride their bikes rather than driving a car. Taking public transit like a subway or a train is still better than a driving your own car because of the number of people that can fit in a train car, but it's still something that we are working on. Many companies have worked with the government to try to create changes to encourage people to do their part to protect the enviroment like rules about recycling and not wasting the resouces we do have - like water!
