Carbon cycle & Eco-Disasters

Scientists have studied oceanic garbage “patches” around the world. These are areas that accumulate certain types of garbage from coastal regions. Their environmental effect ranges from killing sea life to blocking sunlight from reaching photosynthetic organisms. Without a change in human usage, new garbage patches will continue to form. Which human activity would most directly reduce the amount of garbage that enters the ocean?

• Recycle glass

• Recycle paper

• Recycle plastics

• Recycle metals
