Nature isn’t something for us to enjoy. We need it for our survival.

This was the warning from international scientists on Tuesday. The warning was about Earth’s wildlife. 60% of mammals, birds, fish and reptiles have been killed by human activity since 1970.

The report is from the World Wildlife Fund (WWF). It says that human over consumption of land, food and natural resources has killed most wildlife on Earth. This is very dangerous for human survival.

“We are sleepwalking towards the edge of a cliff, said Mike Barnett of the WWF.

Killer whales are in great danger because of chemicals used by humans. Animals in south and central America are the worst affected. 89% of species have been lost there.

The main cause of these losses is deforestation for farmland. The killing of animals for food is the second biggest cause of extinction.

Many scientists believe the 6th extinction is now happening. This is the first time a single species has caused an extinction. The scientists are clear that humans need nature for their own survival. Without nature, humans will also become extinct.
