The Guardian, 8 May 2019:
There is a strong case for dating the start of the Anthropocene to 1950, since which time a million species have become threatened; 1950 coincides with the growth of international travel, leading to the introduction of alien species into vulnerable populations which then collapse. Back in 1950, world population was one-third of its current level. A combination of antibiotics, vaccination programmes and ineffective family planning have seen human numbers rocket past 7 billion, and they are still rising. Finally the demands of humanity have led to deforestation and widespread loss of habitat in every part of the globe.
It is entirely appropriate that the UN and other institutions produce reports documenting the disappearance and decline of most species on Earth. But they will have no impact at all unless they are accompanied by measures to limit human numbers.
