It’s a problem that should matter to you, whether you live near the ocean or not. That’s because it begins wherever people live and ends with damage to resources we all use and enjoy. [Slide 2] It all starts when nutrients get into lakes and oceans. Remember, what’s waste to humans can be food to plants and other creatures. Nutrients feed algae, like they do other plants. Algae grows and blocks sunlight. Plants die without sunlight. Eventually, the algae dies too. [Slide 3] Bacteria digest the dead plants, using up remaining oxygen, and giving off carbon dioxide. If they can’t swim away, fish and other wildlife become unhealthy, or die without oxygen. [Slide 4] But it doesn’t have to be this way. Protecting marine resources starts with sound agricultural and waste management practices. [Slide 5] Nina, look at picture 1. Tell me what is eutrophication and how does it start? [Slide 6] Eutrophication is a big problem. First, it starts with farms. Farmers use nutrients to help crops grow. They put nutrients, like fertilizer, on the ground. Then, it rains. When it rains, those nutrients go into streams and rivers. Finally, they flow downstream into the ocean. The fertilizer helps the algae in the rivers, lakes, and ocean grow. The problem happens when the algae starts to grow out of control. [Slide 7] Nina talked about picture 1 and how eutrophication starts. Now it's your turn. Look at pictures 2, 3, 4, and 5. Tell me how eutrophication affects marine life. Use details from the pictures to support your explanation.
