It’s well known that big animals, like polar bears, are sensitive to climate change. The Earth warms, polar ice【B1】______, and the bears are out of luck. The same goes for tigers, sea lions, elephants. As the globe heats up and natural environments change, all big creatures are potentially【B2】______.

And there are the animals, like birds, that【B7】______ insects.
So how exactly will global warming affect insects? We don’t really know. Some may go extinct. Others could migrate to cooler regions and【B8】______ native insect species there. And this could have all sorts of important implications for crops and entire ecosystems.
What we do know is that because insects can’t【B9】______their body temperature to the same degree as mammals, they’re particularly sensitive to climate change. It’s hard to【B10】_____what will happen to insects as the Earth warms. But it looks like we’re about to find out.
