Earth is losing wildlife at a [faster / fastest] rate than at any time in history. This is [according / accordance] to the new "Living Planet Report" from the World Wildlife Fund. The report says the [globally / global] wildlife population shrank by 60 per cent between 1970 and 2014. The WWF [warned / warn] that: "Earth is losing biodiversity at a rate [saw / seen] only during mass extinctions." Researchers state that most of the [recline / decline] in our animal population is because of "exploding [humane / human] consumption". There are more and [most / more] humans on this planet. We are eating more, overfishing, cutting down trees for [beef / beefy] production, consuming more, and using more energy and natural resources. This has resulted [on / in] a massive loss of habitat for animals.
The report estimates [this / that] only a quarter of the world's land has been untouched [by / as] humans. This means human [active / activity] has greatly affected animals on three-quarters of Earth's [surface / preface] . Researchers tracked more than 4,000 species of mammals, birds, reptiles, fish and amphibians. They say the [loss / lost] of animal life is worst in South and Central America. These [regional / regions] saw an 89 per cent loss in the population of vertebrates in the [post / past] four decades. The WWF wrote: "The astonishing decline [on / in] wildlife population...is a depressing reminder, and perhaps the ultimate indicator, of the pressure we put on the planet." It warned: "We can [be / do] the generation that had its chance and failed to act; that let Earth [slope / slip] away."
