|
|
In what ways are more developed and industrialized countries contributing to the problems associated with the rising demand for water? |
Much of the demands comes from growing population in the developing world, where water is already scarce. Diets are changing to include more foods, such as meat, that require larger amounts of water to produce. Reports predict that if more demand s for water keep increasing, nearly have of the worlds people will face severe water shortages by 2030 |
