Bats are often thought of as flying mice,but they are more closely related to primates, including humans, than they are to mice.

the bat's body is covered by hair, with the exception of its wings.

Vampire bats don't suck blood. They make a small incision and lap up the blood of their hosts.

Solar energy can also be used to make electricity.

solar power plants, like the one in the picture to the right in California's Mojave Desert, use a highly curved mirror called a parabolic trough to focus the sunlight on a pipe running down a central point above the curve of the mirror.

China in particular has long argued that it is too poor to afford the Western luxury of environmental awareness.

China ranks last among 15 nations in its income group (the fifth decile), behind Vietnam. If Colombia, the group's leader, can afford environmental concern, why can't China?

China fares slightly better in protecting its habitat but much worse in measures of industrial ills.

soft-feathered, brownish emu is common throughout most of mainland Australia, although it avoids big cities, dense forests, and deserts.

The emu is the second-largest living bird in the world (the ostrich is the largest), with adult female emus being larger and heavier than the males.

can sprint at 30 miles per hour (48 kilometers per hour) for quite a distance. Emus are the only birds with calf muscles. Their feet have three toes and fewer bones and muscles than those of flying birds. Their strong legs also allow the bird to jump 7 feet (2.1 meters) straight up. With good eyesight and amazing agility, emus can escape most any trouble!

used for scouring arsenic, bacteria and cloudiness out of rural drinking water

There, the residual water from boiling the flat, oval-shaped lobes of prickly pear for salads and other dishes was used to clear up cloudy water drawn from the river before use for cooking or drinking.

Mucilage is the clear, gooey, viscous liquid from within the cactus which helps to seal water inside the plant so it can survive desert-dry conditions.

Many scientists have specified various reasons for global warming effects on the environment and for human life. It is not easy to point one reason for global warming effects, but recently you might have saw many change in global climate. Global warming effects have various consequences such as glacier volume decreasing, rise in sea levels, shrinkage of Arctic and altered fashion of doing agriculture have been named as direct effects on global warming. Secondary global warming effects are extreme weather events, increase in tropical diseases, changes in the timing of seasonal patterns in ecosystems, and drastic economic impact.

Before many times back, many scientist and researchers were hopping that a positive effect of global warming would be increased agricultural yields(outputs), because of the role of carbon dioxide in photosynthesis which might behave in positive manner, but now it resulting in destructions of several crops. In the area of Iceland, due the rising temperatures which have made possible the widespread sowing of barley easily in an effective manner, which was not possible twenty years from now. The net result is expected to be that 33% less maize—the country's staple crop—will be grown. The reduction in rainfall has turned millions of land into deserts.

Insurance industry has been affected very badly with the risk of insurance; the number of major natural disasters has been increased to 300% since 1960s, and insured losses increased fifteenfold in real terms. According to Choi and Fisher (2003) each 1% increase in annual precipitation could enlarge catastrophe loss by as much as 2.8%.
