b.

high levels of mercury found in endangered bat species

d.

all of the above

The answer would be D, because the rising of the temperatures and more exposure of chemicals contributes to all of the issues shown. Plants are damaged from the direct effect of air pollution and the damage from the plants could easy ruin and destroy the ecosystem. High levels of Mercury found in bats can be contributed by the large amount of chemicals and toxins being pushed into the ozone layer. The changes of the alpine ecosystem is a result from the changing of chemicals in the air which is mixed with oxygen.
