Human industry results in the introduction of a variety of harmful chemicals and agents into the environment, degradation of ecosystems caused by manufacturing and operating practices as well as through urban development. Industrial practices are responsible for atmospheric, soil and water pollution in many parts of the world.
Industrial operations that lack suitable oversight, regulatory policies and guidelines have resulted in extensive pollution of the environment. Industrial efforts may produce pollution through use of outdated technologies, inefficient or ineffective waste-disposal practices, and mining and extraction operations that harvest minerals and natural resources from the Earth without regards to sustainability or ecological impact.
Many different industries are responsible for the discharge of toxins and waste into the atmosphere, water cycle and soil. High levels of pollution have been tied to many serious health issues and damage to natural environments that may leave them unfit to support plant or animal life. Human industry is also responsible for the increase of carbon dioxide within the atmosphere, a greenhouse gas responsible for global warming. In most industrialized nations, the industrial community is responsible for the majority of pollution that occurs. Industrial pollution also occurs in developing nations where industrial guidelines and regulations may be more lenient.
