As a result of the degradation, the world is moving closer to several "tipping points" beyond which some ecosystems that play a part in natural processes such as climate or the food chain may be permanently damaged, a United Nations report said.
The third "Global Biodiversity Outlook" found that deforestation, pollution or overexploitation were damaging the productive capacity of the most vulnerable environments, including the Amazon rainforest, lakes and coral reefs.
"This report is saying that we are reaching the tipping point where the irreversible damage to the planet is going to be done unless we act urgently," Ahmed Djoghlaf, executive secretary of the UN Convention on Biological Diversity, told journalists.
Djoghlaf argued that extinction rates for some animal or plant species were at a historic high, up to 1,000 times those seen before, even affecting crops and livestock.
