  • After rodents, bats are the most numerous mammals on earth.
  • Males have a bright orange ruff and wings are black, which contrast with the tawny body fur.
  • African bats fall into two major categories large fruit bats and smaller, insect-eating bats, none of which attack people.

  • Bats are primarily found in forests and savannas. Colonies of bats roost together in tall trees.
  • In some parts of Africa straw-colored fruit bats are considered a delicacy. Elsewhere they are considered pests and killed to prevent the destruction of fruit crops. Studies, however, have shown that bats only eat very ripe and unmarketable fruit and may even help reduce fungi and fruit flies in commercial plantations. Bats are also slaughtered because of superstitions and the musky odors and noise emanating from their roosting places.
  • Bats, like most wild animals, will bite if handled, but if left alone they normally will avoid contact.
  • Bats are versatile. The insect-eating type is a natural pesticide. Bat excrement, called guano, is sold as fertilizer. And seed dispersal and pollination activities of certain bats help tropical forests survive.

Coral reefs water pollution

  • A third of reef-building corals worldwide are threatened with extinction due to climate change and water pollution, according to the first global assessment on the marine creature by 39 scientists.
  • Destructive fishing and the degradation
  • "When corals die off, so do the other plants and animals that depend on coral reefs for food and shelter, and this can lead to the collapse of entire ecosystems," he added.

  • "We either reduce our CO2 emission now or many corals will be lost forever," warned Julia Marton-Lefevre, IUCN Director General.
  • According to the study, the Caribbean region has the highest number of highly threatened corals.
  • As they are home to over 25 percent of marine species -- including fish stocks -- loss of reefs could also impact coastal fishing communities.
  • depend on coral reefs for their livelihoods,
  • reef-building corals in particular were "most vulnerable to the effects of climate change".
  • Sea temperature rises bleach and weaken the algae that give the underwater sea life its vibrant color, and make it more susceptible to diseases.

  • 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%.

  • All major Transportation sources such as Roads, airport runways, railway lines and pipelines, always require time to time maintenance and renewal as they become subject to greater temperature variation. Regions already adversely affected include areas of permafrost, which are subject to high levels of subsidence, resulting in buckling roads, sunken foundations, severely cracked runways and many other related problems.
  • Most of the low-lying countries such as Bangladesh, Indonesia, Netherlands and many other small islands have been affected by sea level rise, in terms of floods or the cost of preventing them. In most of the poorest low-plain countries, land is the only available space, or fertile agricultural land which is livelihood for them. But due to flood they are finding problem now to perform their activities.
