Warning: Tropical animals are down 70% in 40 years

The International Fund for Nature Protection (WWF) says the number of tropical animals that live in freshwater environments has declined most rapidly by 70% in the last 40 years. Even some species such as pink dolphins that live in the Amazon River have completely disappeared in the natural environment.

The Siberian tiger currently has only 400-500 fish in the wild.

WWF 's Planetary Life Index 2010 (LPI) report shows that the current number of individuals of 2,500 animals in the world has declined by more than 30% compared to 1970. Among them, populations of animals Tropical animals and freshwater fisheries have the strongest decline, at nearly 70% in the last 40 years.

WWF scientists warn that the typical animals of tropical forests, such as tigers, turtles, monkeys and hundreds of birds are at risk of extinction. Currently, the number of each species is only a few thousand individuals living in nature.

The reason for the rapid decline of tropical animal species is due to human impacts, including illegal forest exploitation, slash-and-burn cultivation, and over-exploitation of aquatic products. In addition, the rise in global temperature of more than 30% in the past 40 years is also part of the decline in the number of tropical animals.

In addition, WWF also published a 2010 Ecological footprint report, warning people that their resources are being used excessively. Compared to 1970, human demand for natural resources has doubled and is 1.5 times higher than Earth's ability to respond. If we continue to live with current resource use, we will need two planets like Earth in 2030.

The International Fund for Nature Protection has calculated the ecological index of each country in the world by measuring CO2 emissions, water consumption and other resources per capita of a nation's average. there.

According to the report, the top 10 countries per capita carbon emissions are now in the United Arab Emirates, Qatar, Denmark, Belgium, the United States, Estonia, Canada, Australia. , Kuwait and Ireland.
