The world wildlife population is soon going to face a catastrophic future. The universes of mammals, birds, reptiles, amphibians and fishes have decreased to only 48 percent of that was about 40 years ago. Freshwater species have also suffered a lot, with a 76 percent population decrease while marine and terrestrial numbers both fell by 39 percent. The research was made by looking at 10,000 populations out of 3,000 species.
Professor Ken Norris, ZSL’s director of Science, said “If half the animals died in London zoo next week it would be front page news. However, that is happening in the great outdoors. This damage is not inevitable but a consequence of the way we choose to live,”
But, there is still a hope if the politicians and the ordinary public takes some serious actions to take care of the nature and wildlife, the report says.
Marco Lambertini, WWF International Director said “It is essential that we seize the opportunity – while we still can – to develop sustainably and create a future where people can live and prosper in harmony with nature.”
The main reasons for declining populations were the loss of natural habitats, exploitation through hunting or fishing, and climate change.
The report states “If all people on the planet had the footprint of the average resident of Qatar, we would need 4.8 planets. If we lived the lifestyle of a typical resident of the USA, we would need 3.9 planets,”
There are nine plant boundaries to keep an eye on the conditions of nature out of which three thresholds have already been crossed – biodiversity, carbon dioxide levels and nitrogen pollution from fertilizers. Two more were in danger of being breached – ocean acidification and phosphorus levels in freshwater.
“Given the pace and scale of change, we can no longer exclude the possibility of reaching critical tipping points that could abruptly and irreversibly change living conditions on Earth,” the report said.
