Population
“Instead of controlling the environment for the benefit of the population, perhaps it’s time we control the population to allow the survival of the environment.” From ‘The Life of Mammals’ 2002
“If we were to disappear overnight, the rest of the world would get on pretty well. But if they were to disappear, the land’s ecosystems would collapse.” From ‘Life in the Undergrowth’ 2005
“Wherever women have the vote, wherever girls stay in school for longer, wherever women are in charge of their own lives and not dictated to by men, wherever they have access to good healthcare and contraption, wherever they are free to take any job and their aspirations for life are raised, the birth rate falls. The reason for this is straightforward – empowerment brings freedom of choice and when life offers more options for women, their choice is often to have fewer children.”
“There are 3 times as many people on the planet now than there were when I started making natural history programs.”
“Today we’re living in an era in which the biggest threat to human well-being, to other species and to the Earth as we know it might well be ourselves. The issue of population size is always controversial because it touches on the most personal decisions we make, but we ignore it at our peril.” from ‘How Many People Can Live on Planet Earth’, 2009.
“I was born into a world of just under two billion people today there are nearly seven billion of us. Whenever I hear those numbers I can honestly say I find it incredible, triple the number of human beings in what seems like the blink of an eye and the world transformed utterly. Human population density is a factor in every environmental problem I have ever encountered, from urban sprawl to urban overcrowding; disappearing tropical forests to ugly sinks of plastic waste, and now the relentless increase of atmospheric pollution. I’ve spent much of the last 50 years seeking wilderness filming animals in their natural habitat and, to some extent, avoiding humans. But, over the years, true wilderness has become harder to find.” From ‘How Many People Can Live on Planet Earth’, 2009.
“Just as the human population was starting its unprecedented growth spurt in the late eighteenth century, this was published. It’s a first edition of an essay on population by the English clergyman Thomas Malthus. Malthus made a very simple observation about the relationship between humans and resources and used it to look into the future. He pointed out that “the power of population is indefinitely greater than the power of the earth to produce subsistence for man.” Food production can’t increase as rapidly as human reproduction. Demand will eventually outstrip supply. Malthus goes on to say, if we don’t control human reproduction voluntarily, life could end in misery, which earned him a reputation as a bit of a pessimist. But Malthus’ principle remains true. The productive capacity or the Earth has physical limits and those limits will ultimately determine how many human beings it can support.” From ‘How Many People Can Live on Planet Earth’, 2009.
“As I see it humanity needs to reduce its impact on the Earth urgently and there are three ways to achieve this: we can stop consuming so many resources, we can change our technology and we can reduce our population. We probably need to do all three.” From ‘How Many People Can Live on Planet Earth’, 2009.
“Make a list of all the environmental and social problems that today afflict us and our poor battered planet. Not just the extinction of species and animals and plants, that fifty years ago was the first signs of impending global disaster, but traffic congestion, oil prices, pressure on the health service , the growth of mega-cities, migration patterns, immigration policies, unemployment, the loss of arable land, desertification, famine, increasingly violent weather, the acidification of the oceans, the collapse of fish stocks, rising sea temperatures, the loss of rain forest. The list goes on and on. But they all share an underlying cause. Every one of these global problems, environmental as well as social becomes more difficult – and ultimately impossible – to solve with ever more people.” From ‘How Many People Can Live on Planet Earth’, 2009.
