A recent census has revealed that human practices have led to the destruction of wildlife, with two human beings destroying more than half the organisms that lived in nature.
According to a report by the World Wildlife Fund, mammals, birds, fish, reptiles and amphibians have declined by 60 per cent since 1970.
As for the creatures that have been written to survive death by human activities, they have to fight to keep their lives away from "more human crimes."
In the oceans, for example, marine organisms face the harmful effects of global warming and may be suffocated by plastic.
"Communities need to change their behavior to protect food, water and shelter to survive," said Carter Roberts, executive director of the World Wildlife Fund in America, the Washington Post reported.
The report points to some factors that lead to the rapid death of organisms, such as excessive consumption of environmental resources through human activities, such as mining, deforestation and unsustainable agriculture, as well as climate change.
He also talked about how dangerous people are to get rid of undesirable substances, especially plastics, pointing out that within three decades, almost all marine birds will carry the remains of this substance in their digestive system.
Poisonous plastics also reach the fish, which will have serious consequences for humans as well, especially those whose diets depend mainly on seafood.
About 4 billion people eat fish daily as a source of protein, the report said.
He also stressed the danger to plants and agricultural crops caused by humans. More than one-third of the world's crops are pollinated, in part, by animals that, if damaged, will not be pollinated.
Another serious factor is the large population density that leads to "creeps" on natural areas that have not been touched by humans.
The report warns of the "virgin" land degradation from about one-quarter of the world's surface to the 10 by 2050, forcing animals to live in unsuitable environments in a way that could threaten their lives.
