Efficiency

Efficiency is based on how much work you put into something, and how much you get out of it. As you have less and less input, and more and more output, your efficiency increases. The most efficient way to achieve my goal of animal conservation, is by simply putting laws in place to prevent the killing of animals. If laws are in place before animals become endangered, then there is no need to spend extra time, effort, and money trying to help the animals reproduce quickly. You have to prevent the problem, not fix it after the fact.
