2 0.01 percent of all water on the planet is freshwater that can be used by humans and ecosystems.

3 Guess the amount of human waste, in pounds, entering global watercourses each day, according to the U.N.’s World Water Assessment Program.

4 4.4 billion pounds a.1 billion b.459 million c.76 d.4.4 billion

5 What is the minimum amount of water, in gallons, required to produce a day’s worth of food for one person in the United States?

6 One pound of rice takes about 240 gallons of water 1,680 gallons go into creating one pound of grain-fed beef. 528 Gallons

7 How many gallons of untreated sewage, storm water, and industrial waste are discharged into US waters annually? a.2 million b.1.2 trillion c.120 thousand Orinoco river. Photo: Creative Commons.

16 90% of the medicines you take pass through your body unaltered Everything we use over the sink or in water in our households goes down the drain Animal farming operations that use growth hormones and antibiotics also send large quantities of these chemicals into our waters.

18 Scientists are finding cancer causing fragrance molecules inside fish tissues. Ingredients from birth control pills are thought to be causing gender-altering hormonal effects in frogs and fish. The chemical nonylphenol, a remnant of detergent, is known to disrupt fish reproduction and growth. These effects are known as ENDOCRINE DISRUPTION

19 The fish are in trouble Might we be in trouble too? In humans endocrine disruptors are thought to lead to: degraded immune function mental impairment decreased fertility increases in some types of cancers.
