Overgrazing, overcropping, deforestation
The correct answers are:
- Polar ice caps would melt, increasing sea levels;
Because of the rise of the temperatures, the permafrost, glaciers, and polar ice caps would mostly melt. As they melt, they will increase the sea levels significantly because they will introduce much more water into the the seas and oceans.
- Wildlife would have to migrate or die;
With increasing sea levels, as well as change of habitats, lot of animals would find themselves in situation where they will have to migrate, because if they don't, they will find themselves in water and drown, or starve to death.
- Hurricanes and typhoons could increase in intensity;
Because the water in the sea levels will increase, and the water bodies will become even bigger, the hurricanes and typhoons will be able to become stronger and more intense, thus be more destructive as well.

Explanation:
Animal indicator list is a barometer to check how a particular ecosystem is affecting the lives of particular animals. The indicator measures stress or behavior in the ecosystem to know whether to protect the specie or allow them undisturbed
This is to avoid or reduce to barest minimum incidences of extinction of such specie in the ecosystem.
The grizzly sudden reduction in number from well over 100,000 in California to less than nothing in 1942 triggered the need to protect the grizzlies from human destruction and possible extinction. Grizzlies was a national specie and appeared in the flag of California. The population gradually reduced in most of the states of Idaho, Utah, Alaska and many more.
The grizzlies in 1975 were declared protected species to avoid being hunted or trapped by humans and to repopulate them in the areas where they once lived. Their future will depend largely on humans ability to allow them to coexist with them, by setting out a large area for them to live and regroup.
This will go to balance the ecosystem which has been tampered or disturbed by development.
