Transcribed Image Text:Environmental Principle No. 6
Finiteness of Resources
The finiteness of the Earth's resources can be seen in the following ways:
1. Limits to the Earth's carrying capacity. The amount of life the Earth can support
For example a hectare of land can only support about 10 deer, 100 snakes, and
thousand of mice. Over population of one species can lead to an imbalance. An

Transcribed Image Text:environmental issue brought about by exceeding the threshold level of an
ecosystem is extinction. There is natural extinction but man-made factors such as
destruction of habitat is systematically wiping out species of flora and fauna.
In 11,000 to 18,000 Before Christ on Earth (BCE), three species gets extinct per
century. By 1,600, 50 species per century. At present, 1 species per hour.
