Beskrivelse
Very few places on Earth are untouched by pollution. Chemical compounds manufactured by human beings occur in the snow on the tops of the tallest mountain peaks and in the atmosphere beyond to the bottom of Earth’s deepest abyssal trenches. All forms of life are affected by pollution in some way. Some types of pollution, such as light and noise pollution, which involve energy rather than matter, may be easier to manage and control than the chemicals that contribute to various types of air, water, and land pollution.
