The Guardian view on population control: empowering women may not save the environment
The United Nations has published its latest projections for world population. It predicts that the current 7.3bn people on the planet will reach 8.5bn in 2030, and could be 11.2bn at the end of the century. India is expected to overtake China as the most populous country.
The annually updated forecasts are fuel for a strengthening argument that growing population is a critical environmental issue. The logic is simple: increasing numbers of people multiplied by higher average consumption from wood fuel to mobile phones and intensively farmed meat is a double whammy for the environment. The results are depleted raw materials and polluted soil, water and air. Greenhouse gas emissions causing climate change, specifically carbon dioxide, are the common measurement of this relationship. So persuasive is the strand of thought that it has attracted backing from respected public figures such as Sir David Attenborough, Jonathon Porritt and Chris Packham. But it is flawed.
If expanding population is a problem, campaigners on the subject advocate action to slow and stop the rise, if not reverse it. (The UK group Population Matters, for example, says it is “responsible” to have one or two children – below the replacement rate at which population would be stable.) This presents challenges. The first is that much of the rise in population is due to people living longer. Nobody is credibly suggesting that society should cease trying to find cures for disease or stop stepping into disaster zones to save lives.
