Scientists recently discovered that animals who live in groups such as elephants, foxes and wolves are especially likely to follow rules. If they don't and each does its own thing the group might be 1 . Group members would then be forced to live alone and they'd have a 2 time hunting and raising their young. In a way we could say animals have selfish reasons to 3 , that is, it's in their own 4 to do so. But sometimes these same animals go out of their way to do what's right even though there is nothing in it for them.
Take Sniff, 'the African chimpanzee as an example. When this young and 5 animal, who always avoided people, saw a hungry local villager trying to knock some fruit from a tree with a stick to get a meal, Sniff' took a(n) 6 . He picked up an armload of fruits, swung 7 down from the tree-tops and handed them to the amazed villager, And then there is the story of Tobie the generous cat who would always 8 her dinner with the hungry dog that lived next door.
Scientist Mark Benson says, "Nobody is sure why some 9 act this way. It might simply feel good to be 10 , just as it does for humans".

The transition from old fuels to new will be slow, as will the development of new technologies that present feasible alternatives to fossil fuels or help eliminate food and water problems. All current technologies are inadequate, and new ones will probably not be commercially possible by 2025
