What has interested me the most was the last one, which I quote here in entriety, because it's just co much contrary to the philosophy of the New Scientist that I am shocked.
What is the single most effective thing I can do for the environment?
Over a 75-year lifespan, the average European will be responsible for about 900 tonnes of CO2 emissions. For Americans and Australians, the figure is more like 1500 tonnes. Add to that all of humanity's other environmentally damaging activities and, draconian as it may sound, the answer must surely be to avoid reproducing.
Candidness leaves me speechless.
