Modern industrial plants which manufacture steel, cement, chemicals etc, require a lot of land and water and also discharge a lot of pollutants. This has caused the destruction of flora and fauna over large tracts of land. Many people are concerned that irretrievable damage has been caused to the environment, and this will ultimately destroy the human species. However, many environmentalists are fighting back and trying their best to improve the situation. Indeed, the need of the hour is effective action and not to keep worrying about the circumstances.
