World Wildlife Day – Time to Save Half for the Animals

Desperate times call for drastic measures – so believes a certain 87 year old Harvard professor. And these surely are desperate times for much of the planet’s wildlife – flora and fauna. The octogenarian’s plan to save them is nothing if not radical. In fact, at first glance pretty off-the-wall. It is simply,

Half-Earth – giving over half of planet Earth to Nature

His critics dismiss his idea as not just radical, but “truly bizarre, disturbing and dangerous.” 

But is it?  Why should we give over half the Earth? Why should we not? Why this way? Wouldn’t it be bad news for people? Is it even possible?

We will come back to these questions.


Earlier this week during the run-up to World Wildlife Day 2018, conservationists met up in London to mull over matters that could scarcely have greater significance for the future of wildlife, the future of the human race, and the future of Planet Earth itself.
At the Safeguarding Space for Nature – Securing Our Future symposium, delegates from the 200 signatory nations compared notes on their progress in meeting the Aichi Biodiversity Targets, targets set by the Convention on Biological Diversity 7 years ago.
By 2020 they purpose to have 17% of Earth’s land protected for Nature, and 10% of Earth’s oceans. So far we’ve reached 15% and 7% respectively.

“But many conservationists argue that even if these [unduly modest] goals could be achieved, they will still not halt extinctions. The current focus on protecting what humans are willing to spare for conservation is unscientific, they say. Instead, conservation targets should be determined by what is necessary to protect nature.” 

The Aichi targets are, it has to be said, a long way off the audacious proposal ‘half for us and half for the animals’ spelled out by Edward Osborne Wilson in his visionary book, Half-Earth: Our Planet’s Fight for Life. Dr Wilson, the aforementioned octogenarian professor, is sociobiologist, biogeographist, naturalist, environmentalist, author, twice winner of the Pulitzer Prize, and generally considered the world’s foremost authority on biodiversity and conservation. So I guess his ideas and opinions are not to be dismissed lightly.

And indeed, only 2 years on since Dr Wilson’s book was published, his bold half-earth proposal is seeming less and less out there, less controversial, much more mainstream and worthy of serious consideration.

Conservationist Harvey Locke for one jumped feet first on to the good prof’s bandwagon: 50%, he says, “may seem a lot – if you think the world is a just a place for humans to exploit. But if you recognise the world as one that we share with wildlife, letting it have half of the Earth does not seem that much.”

Locke’s own organisation Nature Needs Half now runs in parallel with Dr Wilson’s own, The Half-Earth Project

But now, going back to those questions: why, how, should we, and can we? World Wildlife Day seems the perfect time to take a good hard look at them and try to find some answers.

Why should we do this?

animal-175033__180Well, that’s an easy one. It’s no news to any of us that right now plants and animals are being snuffed out to extinction at a rate unknown since the asteroid Chickxulub wiped out the dinosaurs. Scientists call this the Anthropocene Age, because never before have human beings had such a profound effect on the planet, one that will end badly for us as well as the rest of life on Earth. A truly earthshakingly terrible prospect, especially when we stop to think that right now our precious planet harbours the only known life in the universe. We need a drastic solution to a cataclysmic problem if we are to save this planet and the life on it.

Why this way?

There are two reasons why we should put our energies into a bold plan such as this, Dr Wilson argues. Firstly, he maintains that people like to see a big goal achieved rather than piecemeal, barely noticeable small incremental steps, which is what we have now in conservation efforts: “They need a victory, not just news that progress is being made. It is human nature to yearn for finality, something achieved by which their anxieties and fears are put to rest.” He reads us well. Oh how we long for some major reversal of the destructive path down which humankind is at present rushing headlong.

Secondly and more importantly, as delegates at the London conference were forced to acknowledge, current conservation efforts are doing little to halt the alarming decline in biodiversity. Protecting just 15% of the planet’s land – the course we are on at present – we still look to lose half of all species. It’s much too little and soon will be far too late. Whereas protecting 50% of the planet would mean 80% of species saved – more if we focused on the most biodiverse areas.

frog-643480__180It’s all about the species-area curve, conservationists will tell you. The species-area curve is the mathematical relationship between the area of land and the number of species that can be successfully maintained in it. “The principal cause of extinction is habitat loss. With a decrease of habitat, the sustainable number of species in it drops by (roughly) the fourth root of the habitable area.”

Put simply, the larger the area the better Nature’s chances. The species-area curve also means that setting aside a few sizeable chunks of land is very much better in terms of numbers of species saved, than trying to protect lots of small separate habitats.

And the chunks need to join up: “I see a chain of uninterrupted corridors forming, with twists and turns, some of them opening up to become wide enough to accommodate national biodiversity parks, a new kind of park that won’t let species vanish,” Dr Wilson told the journal of the Smithsonian Institution in Washington. His vision is for a series of “Long Landscapes”, wildlife corridors running vertically down and horizontally across continents, that will allow species free movement as they adapt to the effects of climate change.

The Yellowstone-to-Yukon conservation initiative running 2,000 miles without break from Wyoming in the mid-west of the US to the Yukon territories in the north west of Canada is a model for the protection he would like to see rolled out worldwide. It’s an entire eco-system in 502,000 square miles of continuous protected land where animals can freely roam.

(Sadly America itself is hardly a model nation when it comes to protecting biodiversity. In spite of being a wealthy country, and one with vast areas only sparsely populated, the US can boast just a pitiful 4% of its landmass protected for biodiversity, less than half the average worldwide. If the present ‘leadership’, remains unchallenged, that percentage can only fall further. Donald Trump is pre-eminent among those who think the world is a just a place for humans to exploit.”)

So is Half-Earth a “bizarre” and “dangerous” idea?

malachite kingfisher matthew clayton africaWell if we are looking at the biodiversity statistics – and affirm with Dr Wilson that “each species is a masterpiece, a creation assembled with extreme care and genius” – his idea makes total sense. We have so much to lose. Wildlife he says, is facing “a biological holocaust.” It could barely get more apocalyptic than that. For him, as for many of us, safeguarding the wonder that is life on Earth in all its diversity is a moral issue.

In several interviews, he references the need for humanity to develop an ethic that cares about planetary life, and does not place the wants and needs of a single species (Homo sapiens sapiens) above the well-being of all other species.” Truth Out

What kind of a species are we that we treat the rest of life so cheaply? There are those who think that’s the destiny of Earth: we arrived, we’re humanizing the Earth, and it will be the destiny of Earth for us to wipe humans out and most of the rest of biodiversity. But I think the great majority of thoughtful people consider that a morally wrong position to take, and a very dangerous one.

What would be bizarre is an insistence that we continue as we are doing now, or just nudge the goalposts a bit. The Aichi Biodiversity Targets are Dr Wilson says, “nowhere close to enough,” to prevent the 6th Extinction. Many others agree. It is after all, self-evident.

But his critics, social scientists in the Netherlands Bram Buscher and Robert Fletcher, clearly coming from the very same anthropocentric, the-Earth-exists-for-us standpoint that has brought us to this sorry pass in the first place, judge his Half-Earth vision “disturbing and dangerous.” They are united in their condemnation:“It would entail forcibly herding a drastically reduced human population into increasingly crowded urban areas to be managed in oppressively technocratic ways.” They could justifiably claim history backs them up, since indigenous peoples have indeed been moved out of areas newly designated as protected in the past.
So, wouldn’t Half-Earth be bad for people then, especially the indigenous and poor?

amazon-indians-69589__180Dr Wilson wants to keep indigenous people in their own territories. “They are often the best protectors” of their own land, he says. Protected areas would not mean banning people – simply keeping the land undeveloped. He envisages something along the lines of national parks, where development, and activities like hunting and fishing, are not permitted but there is still regulated access. When local populations find new livelihoods from eco-tourism for example, they become passionate about protecting their natural heritage.

He points to Gorongosa National Park in Mozambique as a model of how well-managed protected areas actually benefit local people.

“The maintenance and expansion of this magnificent reserve has been enhanced by the improvement of agriculture, health, and education – and new jobs – in buffer zones. The same effect is demonstrable even within industrialised nations.” 

And recent research elsewhere backs him up. Protecting areas in Uganda, Thailand and Costa Rica have indeed improved the lives of locals.

Is setting aside the Half-Earth for Nature even possible?

Yes we can, by reducing our ecological footprint. And the best way to achieve that reduction is by moving towards a plant-based dietThen yes indeed, Half-Earth is an achievable goal. Scientists in the fields of conservation, ecology, environment, climate change, sustainability and indeed human health all agree: if people cut back, or better still, stop eating meat & dairy products altogether, many of the deeply disquieting and serious threats to the future of life on Earth would disappear. It’s not just the animals being eaten that we are killing. By destroying wildlife habitats for livestock farming we are killing the wild animals too.  Currently 40% of the world’s land is used for farming. (Urban development takes up only 3%) A whole three quarters of that farm land is used to grow crops to feed livestock. Freed from this absurdly wasteful use of land, it would not be too great a challenge for humans to find a Half-Earth for Nature.

What is stopping us?

According to Dr Wilson, it’s simple – greed, shortsightedness and above all, ignorance. Formidable obstacles to overcome. Ignorance at least can be remedied. We can start by sharing this, why Planet Earth needs Dr Wilson’s bold idea, and what we can do about it, with as many people as we can reach, especially those who haven’t yet found their way to plant-based eating and living.

But to overcome greed and shortsightedness, it’s hearts that need to change.

“When people are encouraged to take a close look at the remnants of Nature, in its complexity, beauty, and majesty, and when they understand that the natural environment is the home of their deep history, many become [Half-Earth for Nature’s] most ardent supporters.”

I’m most definitely one.

  1. I could not agree more, a great idea, implementing it though is a challenge as is getting a consensus to do so. America particularly under Trump is likely to make matters worse, as you say Trump considers the world a free for all for humans to exploit and for the small minority at that. Ignorance can be sorted out, but greed is another matter, it is greed that drives all the disastrous things that happen to our world for both human and non human animals. The earth belongs to no one, we share it with millions of other species and it is time we allowed them more room to live their lives as nature intended. Thank you for another interesting article.
