Various branches of economic activity have played and continue to play key roles in the destruction of the environment. Unsustainable agricultural practices have led to the loss of arable land, and air and water pollution has largely been a result of industrial activity and pesticide application. Transport systems continue to pollute our atmosphere. Environmental pollution is of varied origin. Sustainable development will ensure that the environment is fully protected, and that the health and safety of workers and the community is guaranteed in the long term.
Industry has a particularly bad name as far as pollution is concerned.
But toxic or noxious gases, dusts, vapours, mists etc. may be emitted into the atmosphere thereby polluting the air. Manufacturing industries have contributed greatly and are continuing to contribute to air pollution, both at work and in the outside world. The depletion of the stratospheric ozone layer, global warming, acid rain, etc. Mechanization, which is also characteristic of industrial development, has also created many noise problems in workplaces. Epidemiological studies have shown that air pollution can result in outbreaks of diseases among the human population.
