3．The world has undoubtedly changed in many ways due to the changing climate.Humanity has seen wildfires burn through the rolling hills of California and across Australian forests.Weather patterns have changed，and species of all kinds have had to adapt as well as they can.
A study out of the New England Aquarium in Boston，Massachusetts，focuses on the Epaulette shark and their newly born pups.Native to the warm waters near Australia and New Guinea，this small species of shark is very interesting and adaptive.But all the evolutionary adaptive behaviors don't take these sharks out of harm's way.
Lauren Benoit，a marine scientist，weighed in on this issue， "Studies have found that warmer waters caused sharks to give birth faster and as a result the premature pups were smaller and lacked energy." Lauren continued discussing the real impact of climate change on all sharks. "The problem is that the water is warming so rapidly that these sharks may not have enough time to adapt.The same goes for their prey （獵物），who are also trying to deal with the changing environment.Some species may be able to change their migration patterns to follow the colder water."
The danger is clear and present.Lauren explains： "If these animals are born too soon，then the conditions they need to survive may not be present.Overtime，if some of the babies survive and are able to adapt to these temperatures，then future generations will be able to
withstand the warmer environment."
The warming conditions of the planet will be likely to influence everything living on Earth.Lauren helps us understand why we need to try and stop and change the impact of global warming from a shark's perspective： "Overall，most sharks are cold-blooded and are very sensitive to temperature.As global ocean temperatures warm，it will become dangerous for shark populations."
