      Nice article Nick!
      It puts the 'green revolution' into perspective!

      Right.  "Peak food" is probably going to be about 2030 with a population around 8 billion at that time.  There are too many aquifers going dry, including those in India, China and the US, and while grain yields are going up, it is at a less-than-one-per-cent-per-year rate.  This was the conclusion of Limits to Growth, whose projections are being followed pretty much by the "real world" to date.  See also Arguimbau,  “Peak Food: Can Another Green Revolution Save Us?”. http://www.countercurrents.org/arguimbau310710.htm, in which I failed to take into account probable effects og global warming because they were less clear at the time than they are now..  The powers that be will not permit "no growth" projections.

      Right, Steve,
      Those people make their extrapolations of trends, with no regards of environmental factors.

      I suspect these figures are underestimating increasing mortality and decreasing longevity amongst the vast majority of unlucky and underprivileged .

      India to overtake China's population by 2022 - six years earlier than expected
      Nigeria will replace the US as the world's third most populous country by around 2050. Africa is expected to account for more than half of the world's population growth over the next 35 years. The current world population of 7.3 billion will reach 9.7 billion in 2050 and 11.2 billion in 2100, it predicts.
      UN World Population Prospects 2017
      The population projections are based on the probabilistic projections of total fertility and life expectancy at birth, based on estimates 
      5 Major Effects of Over-Population in India
      These are: 1. Population and Food Supply 2. Population and Unemployment 3. Population and the Burden of Education 4. Population and Housing and Health 5. Economic Consequences of Rapid Population Growth.
