Methane gas would pollute the ocean environment as shoreline organisms begin to die and decay.

Nonrenewable resources in the ocean environment would become depleted and upset the ecosystem's balance.

Alteration in ocean salt levels would cause loss of species and unbalanced populations in marine food webs.

Increased levels of salts and minerals in the ocean would result in overpopulation of marine bivalves due to strengthened shells

rich soil, deciduous trees, 50 inches of last year

Frozen soil, small plants-no trees, 30 inches of rainfall last year

Poor soil quality, great biodiversity, 90 inches of rainfall last year

Competition within the population will increase.

Inbreeding will be less frequent among the remaining population.

The elephant seals will be more vulnerable to environmental change.

The surviving elephant seals will be better able to adapt.

^{The whale populations are bouncing back very successfully and are unaffected by Japan and Norway continuing to whale.}

^{The whale populations have mutated into new kinds of organisms.}

^{The whale populations are not rebounding as quickly as they might if all of the countries agreed not to hunt whales.}

^{The whales are getting better at avoiding capture.}
