Natural disasters play a major part in the destruction of species. Floods, volcanic eruptions, earthquakes, and major changes in temperatures have all contributed to the extinction of many different species in the past. Each species strives to find a niche in their community. At times, a species can be wiped out because of a predator or lack of a food source. The effects of extinction are great.
Many problems can arise from the extinction of a species.
Some species rely on another species to stay productive. Co-dependence plays a major role in extinction. Human effects Humans have been hunting animals for hundreds of years. 14000 years ago humans wiped out almost an entire population of megafauna mammels. Humans also alter the environment of species by changing the plant life in the area and population of air and water supplies around the species.
