Extinction occurs when species are diminished because of environmental forces (habitat fragmentation, global change, natural disaster, overexploitation of species for human use) or because of evolutionary changes in their members (genetic inbreeding, poor reproduction, decline in population numbers).
Do humans cause extinction?
The current rate of human-induced extinctions is estimated to be between 100 and 1,000 times greater than past natural (background) rates. This situation is largely due to the exponential growth in the number of humans on Earth and their activities. Population has increased from about 1.3 billion people in…
