Infelizmente a data limite que é referida no 4º parágrafo do artigo é irrealista por optimista como se dá conta pela urgência inscrita no artigo do link http://science.sciencemag.org/content/357/6357/1242

Assunto: Dióxido de carbono na atmosfera bate recorde dos últimos 800.000 anos

http://www.sciencemag.org/news/2018/08/ ... id=2232294

"The concentration of carbon dioxide (CO2) in Earth’s atmosphere reached 405 parts per million (ppm)...Even if humanity “stopped the greenhouse gasses at their current concentrations today, the atmosphere would still continue to warm for next couple decades to maybe a century,” said Greg Johnson, an oceanographer at NOAA’s Pacific Marine Environmental Laboratory in Seattle, Washington, during a press call yesterday about the report.

Assunto: How many people can live on Earth?

10 years ago the physicist Martin Desvaux deliver a talk to the Royal Society of Statisticians that he later turn into a paper published in "Significance", a journal of the Royal Statistical Society. The title of the paper is "The sustainability of human populations: How many people can live on Earth?" in the end of it we wrote:

“It is not sufficient to try to apply technology to solve the, affluence term in the Commoner-Ehrlich equation. Humans will not willingly sacrifice much of their comfortable lifestyles for the greater good (especially for people in other countries) unless it is taken from them...”

Although very pessimistic this narrative has many advantages, the more important concerns the fact that it points the finger to everyone of us. And only in the moment that we were able to realize that technology will not bring miracle solutions that´s the moment that each one has to do is own part to solve this paramount problem. Higher education has a strong responsability on this context not only by teaching about self-responsability but also about the ethical importance of moderate consumption patterns.

Of course Governments in Western countries have also major responsabilities in sending the rigth signals to certain industries. And they should already been after the auto racing industry the same way that they do with the tobacco industry. Not so much because of their associated emissions but mostly because it is an unwarrantable industry that embodies the "confortable lifestyles" and all the wrong values that Western countries live by.
