Global animal, bird and fish populations have plummeted more than two-thirds in less than 50 years due to rampant over-consumption, experts have said, while human activity has severely degraded three quarters of all land and 40 percent of the Earth’s oceans. The last half-decade has seen unprecedented economic growth underpinned by an explosion in global consumption of natural resources but our quickening destruction of nature is likely to have untold consequences on our health and livelihoods. Whereas up till 1970, humanity’s ecological footprint was smaller than the Earth’s capacity to regenerate resources, the WWF now calculates we are over using the planet’s capacity by more than half Dr Peter Cunningham an Ecologist from Namibia explained to Future Media News.
