Contraception to combat climate change
The Optimum Population Trust, backed by Sir David Attenborough, believes that contraception is the cheapest means of preventing climate change, arguing that every £4 spent on family planning over the next four decades would reduce global carbon dioxide emissions by more than a tonne. Comparatively it would cost £8 for tree planting, £15 for wind power, £31 for solar power or £56 for hybrid vehicle technology before a tonne was saved, according to a cost-benefit analysis done for the group.
The group, also backed by Sir Crispin Tickell, the former diplomat, and environmental campaigners Jonathon Porritt and James Lovelock, believes that 80 million pregnancies each year are unwanted, and the use of contraception would help cut this figure. It is offering people donate through their website, www.popoffsets.com in an attempt to offset their carbon footprint.
