Someone said, ‘‘know a your enemy’’. Today, environ- mental enemies are everywhere. So many, so different, how to know them all? How to know the problems of this planet? Most environmental problems are ultimately due to humanity’s ecological impact on the planet. All organisms make their presence felt ecologically, by using resources and reproduc- ing. The more organisms there are and the more they consume, the larger the ecological impact. In 4000 BCE, there were two million hu- mans. By 500 BCE, 100 million people and today, over six billion homo sapiens. Anyone can guess that our ecological impact is not small and this explains much.

Ozone depletion can thank billions of styrofoam cups and refrigerators. Most envi- ronmental problems are due to the phenomenon of high numbers of people using resources at a rapid rate. The damaging effect. of the planet’s high human population may lead one to believe that the world’s problems rest with the most popu- lous countries, like China, with 1.1 billion and bas chief value for large num. bers of people today i: growth in personal level: of consumption.’ Each of Canada’s 2: million people consume over 40 times as much energy as an averag African, which has the ecological impact 0 over one billion effective people. Global popu lation problems are more accurately viewed 4 consumption problems and that rich nation! like Canada consume a vast proportion of re sources. Many nations of large population, such 4 China and India, already make concerted ¢ forts to reduce population growth.
