I recently read this article in The Guardian. I've reproduced it without permission, but I don't think they would mind and I'm sure the author wouldn't.
The main point, which I really embrace, is that population and population growth is a dangerously neglected aspect of the world's troubles. The author does not directly mention peace and conflict issues but I think they are as worrisome as the environmental issues he describes.
If you find this interesting you might like to follow the link at the bottom to the author's affiliation. I'm glad I did.
The simplest truths are sometimes the hardest to recognise. According to the UN the world population will reach 9.2 billion by 2050. The economist Jeffrey Sachs devoted this spring's Reith lectures to a planet "bursting at the seams". Meanwhile the Gaia scientist James Lovelock has been warning about ecological collapse and world resources able to support only 500 million people.
In the midst of all these alarms is a very quiet place where the green lobby should be talking about human population growth. You will not see any of the big environment and development groups mounting a campaign on population. Indeed you will be lucky if they even mention the P-word. Earlier this year Nafis Sadik, the former director of the UN's population fund, berated such non-governmental organisations for being more concerned with fundraising than advocacy. Their silence on population, she observed, was "deafening".
So why isn't the green movement talking about population any more? In its early days, back in the 1960s and 70s, population growth was a mainstream concern. Groups including Greenpeace, Friends of the Earth (FoE), WWF and Oxfam took well-publicised positions on population issues, endorsing the Stop at Two (children) slogan, supporting zero population growth and publishing reports with titles such as Already Too Many (Oxfam). These days, Greenpeace declares that population is "not an issue for us" and describes it as "a factor [in] but not one of the drivers of" environmental problems.
FoE last year tried to answer some "common questions" on the subject, including: "Why isn't Friends of the Earth tackling population growth?" Oxfam, which as recently as 1994 published a report entitled World Population: The Biggest Problem of All, now does not list it among the "issues we work on", and nor does it figure in the "What you can do" section of WWF's One Planet Living campaign.
The green lobby's main argument is that numbers do not matter so much - it is how we live and consume that counts. FoE even remarks that "it is unhelpful to enter into a debate about numbers. The key issue is the need for the government to implement policies that respect environmental limits, whatever the population of the UK". It is a statement that seems to treat population and environmental limits as entirely separate subjects.
There are two powerful counter-arguments. One is common sense: that consumption and numbers matter and that if a consumer is absent - that is, unborn - then so is his or her consumption. The second is the weight of evidence. Sir David King, Britain's chief scientist, told a parliamentary inquiry last year: "It is self-evident that the massive growth in the human population through the 20th century has had more impact on biodiversity than any other single factor."
The increase in global population over the next 40 years, for example, is roughly what the entire world population was in 1950. The UK, which currently numbers about 61 million people, is on course for 71 million by 2074, by which time England's densities will have outstripped those of South Korea, which, by some measures, is currently the world's second most-crowded country, after Bangladesh.
Ironically the world now views climate change as the greatest environmental threat but sees the solution in primarily technical terms. Yet expert bodies routinely identify human numbers as one of the main engines of climate change. Of the various social and technical factors involved, for example, the UN says: "The link to population is clearest: the more people there are, the higher emissions are likely to be."
Many suspect other motives for the green lobby's neglect of the population issue. It is a sensitive subject, bound up with issues on which the progressive left, with which most environmental groups identify, has developed a defensive intellectual reflex. These include race and immigration, reproductive choice, human rights and gender equality. Calls for population restraint can easily be portrayed as "anti-people". It is far easier to ignore the whole subject.
This often involves intriguing verbal contortions. The 70s organisation Population Countdown, having morphed into Population Concern, in 2003 rechristened itself as Interact Worldwide, under its former name, consultants told it, its funders, and future, would dry up.
How to categorise such reactions? Pragmatism? Cowardice? Sensible tactics? Or an overdose of organisational self-preservation? Whatever the reason, it is infectious: the media (and politicians) take many of their awareness cues from NGOs so the silence on population becomes society-wide. As a result family size is seen as an exercise in individual lifestyle choice: few people consider the consequences for the planet of their fertility decisions. That means fertility rates in the UK rise, and the population keeps on growing.
It was Mark Twain who observed that those who refused to share vital information with others were guilty of a "silent lie". The green movement needs to start telling us the truth.
