Ian Barbour. This entire planet is our home. We are the only species that systematically destroy our own habitat. Pollution prevention is a major global concern because of its harmful effects on people's health and the environment. Because we are all inhabitants on Earth, everyone is a stakeholder, and every person has something to contribute to advance effective pollution prevention and awareness.
Pollution is the introduction of contaminants into the natural environment that cause adverse change. Pollution is often classed as point source or nonpoint source pollution. In , pollution killed 9 million people worldwide. Major forms of pollution include air pollution , light pollution , litter , noise pollution , plastic pollution , soil contamination , radioactive contamination , thermal pollution , visual pollution , and water pollution.
Malthusianism is the idea that population growth is potentially exponential while the growth of the food supply or other resources is linear , which eventually reduces living standards to the point of triggering a population die off. This event, called a Malthusian catastrophe also known as a Malthusian trap , population trap , Malthusian check , Malthusian crisis , Malthusian spectre , or Malthusian crunch occurs when population growth outpaces agricultural production , causing famine or war , resulting in poverty and depopulation. Such a catastrophe inevitably has the effect of forcing the population quite rapidly, due to the potential severity and unpredictable results of the mitigating factors involved, as compared to the relatively slow time scales and well-understood processes governing unchecked growth or growth affected by preventive checks to "correct" back to a lower, more easily sustainable level. These concepts derive from the political and economic thought of the Reverend Thomas Robert Malthus , as laid out in his writings, An Essay on the Principle of Population.
