Scientists' warning is not heard - or at least not acted upon

Scientists have been trying to alert the public about how the present way of life is not sustainable ever since 1970’s. A very strong message with more than 10000 scientists endorsing the publication of data was written in 2019 indicating that unless strong measures are taken, many tipping points leading to drastic environmental deterioration are reached in the near future. After 2019 the Coronavirus pandemic hit the world, and the lead authors of the 2019 paper thought that it is good time to see, if any measures have been taken to heed the warning. In BioScience this July 28 (https://doi.org/10.1093/biosci/biab079), Ripple et al. estimated what has happened during the pandemic time. For the most part the findings are bleak: the temperature, carbon dioxide, methane and nitrous oxide levels continue to increase, Antarctic, Greenland and overall glacier ice mass continue to decrease at a similar rate as before. What is almost worse is that although many climate-friendly changes took place as a result of the pandemic, almost all have started to revert to pre-pandemic levels. For example, the number of livestock has continued to increase, and all the media are just saying how we need to get the economic growth back to pre-pandemic track.

In the overall gloomy picture there are, however, a couple of bright spots. The first is that the number of births per woman continues to decrease. For ending up with sustainable human population, this is probably the most important trend and should be supported by improving the education of women. The second is the marked decrease in subsidies to fossil fuels. It has been quite funny that the same groups, who have been very vocally against any subsidies to green energy production, have wanted and accepted billions of dollars/euros in subsidies to oil and coal industries.

Stabilizing and reducing the human population by voluntary actions is the key behind making the life sustainable for all citizens of the world. Only with decreasing population can enough environment be kept in natural state to maintain biodiversity and to reduce the risks of new pandemics. Life in the globe with limits requires social justice, not that some superrich burn a lot of money to a few hours space travel.
