By the year 2050, more than four billion people may go hungry.
Temperature, rainfall, drought,
pollution, floods,
urban
sprawl, disease, and politics all affect the world's food and
water. Modern farming can improve food production but can also
deplete water supplies and poison land. Technologies such as
modifying plant and animal genes
may offer solutions, but can cause problems too.
This chapter takes a look at worldwide food production and water
usage. Explore the tough—but necessary—choices that
we must make. It's a lot of food for thought!
