Resource Depletion (cont.) Although renewable resources are replaced, they can be depleted. Although renewable resources are replaced, they can be depleted. To Sustain our Resources we must: 1. be very careful about how we use non- renewable resources. 2. learn to use renewable resources at a rate that allows them to renew themselves. 3. reduce, reuse and recycle whenever possible.

Pollution Humans have unintentionally and intentionally poisoned the planet for years. Humans have unintentionally and intentionally poisoned the planet for years. Pollutants affect all living organisms at varying rates, and many are dangerous to human health by causing general ill health, disease, cancer, birth defects and nerve damage.

Greenhouse gas emissions are directly responsible for global warming, and since Canada is among the world's highest per capita producers of greenhouse gas emissions, Canadians have a moral obligation to take the lead in dealing with this problem.

Air pollution not only leads to global warming, it also contributes to the destruction of the ozone layer and causes acid rain.

Reductions in Biodiversity and Extinction. Extinction is a natural process of evolution. Extinction is the death of a species—it means that the last member of the species is gone forever.

Presently, thousands of species become extinct every year. Presently, thousands of species become extinct every year. According to renowned environmentalist E.O. Wilson, 20% or more of the Earth's species will disappear during the next 30 years. According to renowned environmentalist E.O.

Many people now understand that all life is interconnected and that what happens to one species directly and indirectly affects thousands of others.
