What is the Half-Earth theory?
Half-Earth proposes an achievable plan to save our imperiled biosphere: devote half the surface of the Earth to nature. In order to stave off the mass extinction of species, including our own, we must move swiftly to preserve the biodiversity of our planet, says Edward O.
What is Wilson’s Half-Earth vision for the real living world?
Wilson champions the goal of Half-Earth— protecting half of the planet, both land and sea. In his 2016 book, Half-Earth: Our Planet’s Fight for Life, he makes the case that doing so would save more than 80% of all biodiversity.
Where can half of the planet’s species be found?
It’s estimated that tropical forests alone are home to more than half of the planet’s species. This is important because, unfortunately, this also where the greatest threats to wildlife exist today.
What is the upper half of the Earth called?

Is Half-Earth a good idea?
According to the Half-Earth Project, which is associated with the E.O. Wilson Biodiversity Foundation, devoting half of the global surface to nature would protect 85% of today’s species from extinction.
Who do we share Earth with?
With the addition of approximately 50,000 vertebrates (birds, mammals, amphibians and reptiles), 400,000 plants and possibly 1.3 million other organisms (mostly microorganisms, but excluding the bacteria for which we know very little about), this leaves us with a best estimate of around 5.5 million species with whom we …
Is Half-earth a good idea?
Is it possible to set aside half the Earth as protected nature reserves?
The reason why half is the answer, according to Wilson, is located deep in the science of ecology. “The principal cause of extinction is habitat loss. By preserving half of the planet, we would theoretically protect 80% of the world’s species from extinction, according to the species-area curve.
What country is at the bottom of the world?
Amazing Antarctica Antarctica is a place of extremes. It’s the southernmost continent and hosts the coldest temperature ever directly recorded on Earth’s surface — a bone-chilling minus 128.6 degrees Fahrenheit (minus 89.2 degrees Celsius) logged at Russia’s Vostok research station.
