|
Enormous amounts of water must be used to produce chemical fertilizers
|
Detailed explanation-1: -Many countries in Southwest Asia are experiencing the increasing problem of water pollution. Farmers have begun using chemical fertilizers that run off from the fields and contaminate water supplies. Chemicals also lead to salt build-up in the soil, which eventually makes farming in those areas impossible.
Detailed explanation-2: -How has the use of chemical fertilizers affected the water supplies in many countries in Southwest Asia? Water supplies have been contaminated by the chemicals through runoff from the fields.
Detailed explanation-3: -Southwest Asia’s biggest pollution problems come from human sewage, agricultural runoff, and industrial waste. Rapid growth of industry in cities and towns has caused garbage and sewage to build up in rivers and streams. Towns without proper sewer systems dump untreated human waste directly into rivers.
Detailed explanation-4: -Much of Southwest Asia is desert, so there is not a lot of water to use for drinking and irrigation. Water is not equally distributed; close to none of the countries in Southwest Asia have a good water source; this has been the cause for many clashes, including the 6 Day War, which was fought over water.
