Weather

Human Impacts:

-Pollution: 80% of marine pollution comes from the land -> run off of fertilizers

-Overfishing= threatens biodiversity of fish, bad for ecosystem! :(

-Tours/development= disrupts enviornment

-Climate= sea temp. rises, sea level rises

-Dead zones: excess decomposition of organic material

Too much algae -------> too much oxygen being used up from H2O

HELP:

1. Build Artificial Reef

2. Limit fishing
