A species may become extinct becasue it's habitat has been destroyed or because the enviroment changes in a direction that is unfavourable to the species. A mass extinction occurs when there is a sharp decrease in the number of species in a relatively short period of time.
Throughout time, there has been much mass extinction on this planet. To this date, there have been at least 5 mass extinctions throughout the planet. All these has been caused by natural ways, such as meteorites crashing into the planet, causing a climate change, volcanic eruptions also causing a climate change, the reversing of the magnetic poles, creating a temporal disappearance in the magnetic field, which allows the suns harmful rays to enter the atmosphere, and many other theories.
Now, considering all the damages we are doing to the environment, such as: Global Warming, War, Pollution
Do you believe that the human race will drive ourselves into extinction or al least create a mass extinction? Why?
