Scientists have warned that the Earth is going through its sixth mass extinction with human activity being the main cause of the cataclysmic event.
Global warming, pollution, overfishing, hunting, and the conversion of ecosystems into farmland are all caused by human activities which may point towards a slow-moving mass extinction.
According to a recent study, Earth appears to be heading towards a mass extinction at a rate 10 times faster than originally estimated. It says that extinction is a normal part of the evolutionary cycle that normally runs at a rate of 10 percent every million years or one extinction per million species years [one extinction per million species per year]. The study estimates that the current extinction rate sits close to 0.1 extinctions per million species years.
According to the International Union for Conservation of Nature’s Red List of Threatened Species, over 40,000 species are facing the threat of extinction currently. It adds that estimates account for 28 percent of all assessed species.
The studies caution that there are numerous species around the globe that are threatened due to habitat loss. This results in them being at a risk of going extinct in the next thousand years.
