Too Many Nutrients
Plants and animals need nutrients, or “food,” such as nitrogen
and phosphorus, in order to grow. However, if an estuary has too
many nutrients, too much algae will grow, creating algae blooms.
These algae blooms block sunlight and can suffocate fish and plant
life by using up valuable oxygen from the water. Nutrients can enter
estuaries from sewage
treatment plants, septic
used in farming and on lawns, and polluted air from power plants and
