Which practices can be used to protect our supply of freshwater? (more than one answer) decrease biodiversity improve waste management systems increase conservation reduce trade restrictions reduce dependence on fertilizers and pesticides

You would INCREASE BIODIVERSITY, so the first answer is wrong. You see, the more species in an environment, the more it is regulated and kept in balance. If species die off, or if some are too high in population, it can result in polluting the environment. Also, restrictions are important to make sure trading doesn't interfere with natural fresh water sources. Decreasing waste and toxic chemicals helps protect our fresh water, on the other hand.

The correct answers are: improve waste management systems, increase conservation, and reduce depends on fertilizers and pesticides.
