This pollution still causes environmental damage, takes a lot of money, time and energy to deal with, and most importantly, it was still created in the first place. P2 aims to reduce the total amount of waste created before it has to be treated. Using energy is one of the largest sources of waste and pollution, however, our society is dependent on energy. Emissions from fossil fuel power plants, automobiles, strip mining, and nuclear waste are all pollution which result from energy use. Pollution prevention programs look for ways to improve energy efficiency in everything from heating and air conditioning, to more efficient automobiles and electric motors, and lighting.
Energy efficiency reduces pollution to air, water, and land.
Very little in nature is wasted, and waste from one organism almost always is useful to another. We can say that nature is self-sustaining . Humans have chosen a non-sustainable approach. Our life-style depends on a constant flow of new natural resources from the earth. Eventually we will begin to run out of resources.
