"World Nature Conservation FundAccording to the announcement made by the World Wide Fund (WWF), the number of animals living in wild land, sea, and river has decreased by more than half compared to about 40 years ago. Its main reason is the development of natural environment and deforestation for people to do "civilized living" to prepare foods lining up with energy and table, and the situation to ask people about the way of life in the future It is getting.

WWF's "Living Planet Report: Living Earth Report", Compared to the 1970s about 40 years ago, the number of wild animals is more than half58% decreaseIt has been shown to have done. The reason is "pollution" and "destruction" to the habitat of animals as a sacrifice of nature destruction due to "consumption behavior" of people.

The number of animals in each habitat from 1970 to 2012, the animals inhabiting the sea such as fish36% decrease, And living creatures living on land such as elephants38% reduction, And living creatures living in freshwater environments such as rivers81%, the greatest decreasedoing. Also a reduction in the number of dramatic populations in several species of birds has been reported.

According to Dave Tickner, Chief Advisor for WWF Freshwater Environment, "Rivers are the mainstay of natural systems". The river has the role of finally taking over the dirt that occurred on land, stopping it, and suppressing flood damage. " There are also 45,000 dams mainly in the world, and these disturb river water flow because they divide the river finely. There are about 45,000 dams in the world with a height of 15 m or more. According to Mr. Ticker, these dams say that "clean water flows are damaged because they divide the river into small pieces". In addition, although the world population has doubled compared to 50 years ago, the consumption of water is seven times higher, and by combining these, "human creatures and river creatures will fall into water shortage "Tickner says.

In WWF's report, the declining tendency of the number of animals is indicated by the index "Living Earth Index" (LPI) which measures the scale of change in organisms, and the population of 3430 kinds of animals tends to decrease It is said that there is. According to the WWF survey, the cause of No. 1 is "development by human beings", and the other main reasons are as follows. LPI has surveyed land areas around the world, fresh water areas such as rivers and lakes, more than 10,000 populations of over 3000 species of wildlife inhabiting the ocean, and calculated based on how much the population has decreased It is an index which is also adopted in "International Convention on Biological Diversity" concluded in 1992.

37%:"Exploitation (Development)"
31%:"Habitat degradation / change (deterioration / change of habitat environment)"
13%:"Habitat loss (disappearance of habitat)"
11%:"Other"
7%:"Climate change"


Professor Ken Norris, a natural scientist at WWF, said: "If half of the zoo animals in London's UK are dying next week, it will be a big news, but in half of the animals that are in nature I am awake. "

Professor Norris said "Nature is essential to bringing foods, clean water, and air to human beings", and deterioration of the natural environment in which animals live affects not only animal life but also our life I am doing. "Decrease in the number of animals" such as wildlife is closely related to convenient "civilized life" such as the electricity and water supply that we are doing, not foods in the mountains, the sea and distant countries, There is a relationship. According to Mr. Mike Barratt, Director General of Science and Policy at WWF, it is necessary to protect the earth from deforestation and development in order to enable the stable sustainment of human food and energy, and "This natural sacrifice is, It is a result that people have chosen and can be avoided. "

Also in this report, it is calculated how much natural resources are necessary for human beings performing civilized activities in the future. For this calculation, an index showing the load on human environment by the environment "Ecological Footprint"(EF) index is used. If we calculate the natural resources necessary for maintaining our lives in the future for the entire human being while keeping the current pace of consumption of natural resources,One earth and one halfThe amount of 'natural resources are necessary'. Also, in order for human beings as a whole to maintain British style living2 Earth and halfOf natural resources, and for the whole humanity to live in American style, howFour pieces of earthNatural resources are calculated as being necessary.

Regarding efforts to protect the natural environment by nation, natural environment, such as industrialized countries, is improving a little by natural conservation activities. On the other hand, poor countries such as developing countries saw a significant decrease in the number of animals. However, nature destruction in a poor country by rich country companies and others "Natural destruction outsourcingThere is the present condition that it is done. This is a company of a rich nation who wants to be a poor country, develops the habitat where the nation's animal lives, produces food, and imports it into its own country. For example, one third of goods such as lumber, beef, soybean, etc. that were produced in a poor country from 1990 to 2008 along with natural destruction were exported to the EU.

However, there seems to be faint hope. An otter of an animal overexposed and hanged for fur in the UK, which is endangered, avoids the crisis by environmental conservation activities,I am returning to the river and are starting to liveAnd that. Likewise, the number of wild tiger individuals that had been decreasing in Nepal also depends on the results of environmental improvementIncreasing tendencyAccording to the government survey in 2013, there were also areas that had more than tripled in three years. In the same way, the number of wild tiger individuals that had been decreasing in Nepal also contributed to the improvement of the environment In Germany,Wild wolves are increasing the numberThere is a report.

David Nussbaum, UK WWF Chief Executive Officer, commented on this report, "The indexes shown here would like people to be a warning to wake up about the natural crisis." Also, "Politicians, business circles and all of us should have interest and responsibility for actions to protect healthy and valuable future for both nature and human beings."
