I believe that everyone has an obligation to preserve the environment. For example, the oceans are in terrible shape because crew ships are dumping waste into the water. Humans may occupy these ships, but we do not make them dump waste. Also, oil spills drastically affect the well-being of animals that inhabit these bodies of water. We use oil and oil biproducts every day.
Oil provides heating for warmth and gasoline for transportation.
Rainforests are cut down to sell wood and clear the land for farming. Companies cut these forests down. The average citizen does not benefit from rainforests being cut down. Overall, humans do have an obligation to protect and preserve the environment, but consumption should not be the first act to modify. If everyone consumed what they wanted and didn't care about what effect their actions took on the environment, all of the world's resources would be depleted.
