According to the new report of WWF, the world’s wildlife has halved in the past 40 years, because of indefensible human consumption and damage from climate change destroying valuable habitats at a very fast rate.

The figure of vertebrates, which make up the bulk of Earth’s noticeable animals, has dropped by 52 per cent and this drastic loss is at its critical level.

The society’s information said humans are cutting down trees more rapidly and destroying natural forest, this thing is affecting on weather change, although the effect of climate change on species until now is very disturbing. This is the main reason of declining the population of wildlife.

The director of science and policy Mike Barrett said that We have destroyed one half of the animal inhabitants and knowing this is made by human consumption, this is clearly a call to arms and we must act now, he said more of the Earth must be protected from expansion and deforestation, while food and energy had to be produced according to the demand.

The sudden turn down of animal, fish and bird numbers was analyzed by investigating 10,000 dissimilar populations, covering 3,000 species in total and this information was then, for the first time, used to make a representative “Living Planet Index” (LPI), reflecting the state of all 45,000 known vertebrates.

The researcher said that the main reason of the decline is also because the developing nations has been on a low income so they are importing food and further goods produced by habitat destruction of rich nations to earn money for example, a third of all the products of deforestation such as timber, beef and soya were exported to the EU between 1990 and 2008.

WWF chief executives said in a report that the scale of of the damage mentioned in this description should be an alarm call for us all.
