Identify at least 2 reasons that it is a challenge to manage water resources so that ecosystem needs are met?

Answer 1

Where to start. Water is a limited commodity, and as much as we need it for crops and livestock, natural ecosystems need it also to support fish, plants and microorganisms.
Challenge 1: How to provide an adequate water supply to farmers who can effieciently use it for agriculture or livestock, while at the same time balancing the needs of spawning fish and wildlife so as not to cause a collapse of strained ecosystems.
Challenge 2: How do we control the amount of runoff produced by the use of water, fertilizers and pesticides in farming. Many fertilizers and pesticides end up filtering into streams and creeks and polluting the water.
Challenge 3: How to manage wastewater produced by residences, businesses and runoff so that it doesnt contaminate the water supply for any other uses.

Answer 2

The ecosystem will take care of it self with out the intrusion of man. That is the biggest problem with man he thinks he is the cure all of everything. When the truth of the matter he causes more damage than good.
