How does changes in the environment may affect species extinction?
Instead, climate change was found to typically lead to local extinctions and declines by influencing interactions between species, such as reducing prey populations for predators. … However, where causes have been identified, changing species interactions have been found to be key in the majority of cases.
How does global warming cause mass extinctions?
A massive extinction event that took place 200 million years ago may have been caused by climate change, new research suggests. The findings shed new light on the pace of mass extinction, and imply that relatively small changes in atmospheric carbon dioxide levels may be enough to trigger an extinction event.
How does global warming affect mass extinction?
Global warming will invariably result in the mass extinction of millions of different species, humankind included. … As a result, food and fresh water sources are being drastically reduced. Then, of course, there are the rising global temperatures themselves, which many species are physically unable to contend with.
What caused mass extinctions?
What causes mass extinctions? Past mass extinctions were caused by extreme temperature changes, rising or falling sea levels and catastrophic, one-off events like a huge volcano erupting or an asteroid hitting Earth. We know about them because we can see how life has changed in the fossil record.
