Currently only about 3,500 adult tigers live in nature

According to the latest survey conducted by WWF, London Animal Association and many other organizations, tiger population is now falling at the lowest level of all time and probably less than 3,500 adults in the Of course.

Meanwhile, overfishing has caused a "catastrophic" loss of fish such as northern bluefin tuna in the western Atlantic Ocean.

The survey also estimates that with the demand of 7 billion people in the world today, the Earth needs 1.5 years to produce and replenish natural resources that are consumed in just one year. This also means that demand now exceeds supply.

In fact, there has been a shortage of freshwater in some countries. Statistics show that 2.7 billion people live in areas with severe water shortages of at least 1 month during the year. This situation will get worse as the world population is projected to increase to 9 billion by 2050.

Survey results are published just before the United Nations Environment Summit in Rio de Janeiro.
