Chain Reaction-
What a lot of people do not realize is that by doing one, what seems like simple, thing, a chain reaction can be triggered and affects that were not intended can occur. For example, an anti-inflamatory drug given to cows, caused three different types of vultures to be endangered from consuming the drug from the dead cow carcasses. Since feral dogs are scavengers as well, and they now do not need to compete with the vulture, they thrive because they are not affected by the drug and increase the threat of rabies. All of these affects were completely unintended, yet still occurred from something that seemed so small, showing how delicate nature is.
Hot-Spot Strategy-
I can see how a Hot-Spot Strategy would not the best approach because not all areas that are high in plant diversity support a high animal diversity. Humans are very dependent and reap the benefits of plants for food, medicine, etc. So if there is an are with a high level of plant variety, humans may suffer fro this loss, and it is possible that we are conserving very few animals in the process.
Disastrous Habitat Loss-
Some of the areas that are at higher risk for natural disasters are also at higher levels of habitat loss. If we combined our efforts we could protect these natural populations while preserving human populations and civilizations simultaneously. How does this not benefit everyone? Mankind benefits as well as the ecosystem/ecosystems in question.
