Remember that humans have only existed for about 200,000 years. This is usually defined as about 75% of the world's species. Throughout earths history there have been an estimated four billion different species, 99% of which have become extinct.

According to a recent analysis, the sixth mass extinction of wildlife on earth is accelerating. About 98% of all the organisms that have ever existed on our planet are now extinct. The high extinction rate is due to the massive growth in human population, which went from about 1 billion in 1850, to 2 billion in 1930 and more than 6 billion in 2000. A scientist declared during a documentary that the world is deep into the sixth mass extinction event, which may be “too late” to change. The same number were lost over the whole of the last century.
