Environmental responsibility is vested in the Ministry of Industry and Agriculture. An Environmental Protection Committee was created in 1984 to monitor environmental problems. Conservation of oil supplies, preservation of the natural wildlife heritage, and increasing the water supply through desalination are high on Qatar's environmental priority list. Air, water, and land pollution are also significant environmental issues in Qatar. In addition to smog and acid rain, the nation has been affected by the air pollution generated during the Persian Gulf War. Pollution from the oil industry poses a threat to the nation's water. The nation's soils have been damaged by pesticides and fertilizers, and its agricultural land is in danger of desertification. Endangered species include the hawksbill turtle, green sea turtle, and white oryx.
