Part 1;
Because there is only limited amounts of fresh water on the Earth the rest is salt water; which humans can not survive on as the salt dehydrates our bodies instead of hydrates.
1) The more we try to get the the fresh water the more we will likely make more pollution. 
2) The more we use the less there is.
3) Everything needs water.
Part 2; no idea I believe it is the ice caps, as it is fresh water in the ice caps and not a lot of humans up there to pollute the runoff.

Answer:
A. the basic unit of life is the organism
Explanation:
According to the organismal theory, organisms are the basic unit of life. The organismal theory contradicts the cell theory of life. The organismal theory states that some of the organisms do not have distinct cells. For example, fungi.
Since the cells in the multicellular organisms are interconnected by one or other means, organisms are the structural unit of life; not the cells. 
The organismal theory states that irrespective of the level of body organization present in an organism, all the components such as cells, tissues, organs, etc. work together to facilitate growth and development of whole organisms.
