What is eutrophication?
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
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
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
But it doesn't have to be this way
Protecting marine resources starts with sound agricultural and waste management practices
