Earths real environmental problem is direct co-opting or destruction of natural ecosystems by humans. "Climate Change" is, for the most part, a bullshít scam pushed by UN bureaucrats, professional parasites, fraudsters, activist wingnuts and corporate criminals. We could eliminate all CO2 emissions tomorrow and the planet would still die. Climate Change is beside the point. The only way to save the diversity of life on planet Earth from direct destruction by human beings is to designate half of it's land and sea area as strictly protected reserve. This is the startling claim of Edward Wilson, based on a lifetime's study of the mathematics of island biogeography
Known as the father of sociobiology, he is also hailed as the pre-eminent champion of biodiversity: Wilson coined the word “biophilia” to suggest that people have an innate affinity for other species, and his now widely accepted “theory of island biogeography” explains why national parks and all confined landscapes inevitably lose species.Wilson recently calculated that the only way humanity could stave off a mass extinction crisis, as devastating as the one that killed the dinosaurs 65 million years ago, would be to set aside half the planet as permanently protected areas for the ten million other species. “Half Earth,” in other words, as I began calling it—half for us, half for them. A version of this idea has been in circulation among conservationists for some time.
In ‘Half Earth,’ E.O. Wilson Calls for a Grand Retreat
Can the World Really Set Aside Half of the Planet for Wildlife?
Massive connected tracts of land and ocean are required to avoid mass extermination of species with unknown implications. Re-wilding of the land and the oceans is perfectly feasible. We are simply not protecting enough of the planet.
Already, wild terrestrial mammals constitute only 3% of the total terrestrial mammal biomass.
We need to imagine Ireland with half our land area as strictly protected national park. People can still visit, but they cannot build, farm, pick, shoot, poison, fish, chop vegetation or collect wood.
Ireland has only 650km2 of National Park for just under 1% of our land area. Half-Earth would imply an increase of the area by a factor of 50.
We need to let Nature rip or our species is gonna die nasty.
