which of the following is a threat that is particular to our fresh-water supply typical for coastal areas?
-Many technologies that are already available can help us save enough water to hedge against climate change and reduce stress on threatened natural resources while still allowing us to meet our -needs for agricultural, industrial, and residential use.
-By 2020, enough water can be saved from indoor residential uses alone to meet the needs of over 5 million people.
-Proper irrigation can save another 450 thousand-acre-feet (KAF) of water per year. This is enough to satisfy the needs of another 3.6 million people (1 acre-foot supplies two households of four people for a year).
