- GOOD! It keeps the earth warm so life can be present.
- what is Bological Oxygen Demand? (BOD)
-
Oxygen needed to break down material
High BOD=bad
low BOD=good -
Why are exotic species bad?
(4 reasons) -
~disrupt complex ecosystems and degraged habitats
~reduce biodiversity, and endanger native plants and animals
~hybridize with native species altering genetic diversity
