Environment - current issues:

shrinkage of the Aral Sea is resulting in growing concentrations of

chemical pesticides and natural salts; these substances are then

blown from the increasingly exposed lake bed and contribute to

desertification; water pollution from industrial wastes and the

heavy use of fertilizers and pesticides is the cause of many human

health disorders; increasing soil salination; soil contamination

from buried nuclear processing and agricultural chemicals, including

DDT

Protocol, Desertification, Endangered Species, Environmental

Modification, Hazardous Wastes, Ozone Layer Protection, Wetlands
