According to the new report WWF and the Zoological Society of London , The number of wild animals living on Earth is set to fall by 2/3 by 2020.The Analysis, which is the most comprehensive to date, indicates that animal populations plummeted by 58% between 1970 and 2012.
The creatures being lost range from mountains to forests to rivers and the seas and include well-known endangered species such as elephants and gorillas and lesser known creatures such as vultures and salamanders.
The biggest cause of tumbling animal numbers is the destruction of wild areas for farming and logging: the majority of the Earth’s land area has now been impacted by humans, with just 15% protected for nature. Poaching and exploitation for food is another major factor, due to unsustainable fishing and hunting: more than 300 mammal species are being eaten into extinction, according to recent research.
“We are no longer a small world on a big planet. We are now a big world on a small planet, where we have reached a saturation point,” said Prof Johan Rockström, executive director of the Stockholm Resilience Centre, in a foreword for the report.
He said humanity was completely dependent on nature for clean air and water, food and materials, as well as inspiration and happiness.
