A fascinating Guardian article from its ‘Overstretched Cities Series’ on urbanisation, as population pressure on the planet continues in the least economically developed parts of the wo rld:
What happens to those cities over the next 30 years will determine the global environment and the quality of life of the world’s projected 11 billion people. It’s impossible to know how exactly how cities will grow, of course. But the stark fact, according to the United Nations, is that much of humanity is young, fertile and increasingly urban. The median age of Nigeria is just 18, and under 20 across all Africa’s 54 countries; the fertility rate of the continent’s 500 million women is 4.4 births. Elsewhere, half of India’s population is under age 25, and Latin America’s average age is as high as 29.
The flow of evidence and dire projections about human impact on the planet continues amid the distractions of the daily news dominated by US politics, Brexit negotiations, China’s emerging global ambitions, suspected Russian nerve agent poisoning, Facebook abuse of personal data and endless fascination with celebrities, to list but a few. Probably a small portion of the public engages with sources such as those featured on this website, despite the alarming trajectory that they reveal.
The Millennium Alliance for Humanity and Biosphere (MAHB) from Stanford University is one of the sources providing crucial analysis of what is happening to our planet. In its latest on-line post from which the following conclusion is taken, maps and graphs of ice loss and sea level rise are provided. They show how rapidly ice is turning into water on our planet
“The average global sea level is already 82 mm above the 1993 average and is continuing to rise at the rate of around 3 mm/year.
the temperature at Antarctic is rising more quickly than the global average, and it is losing about 118 gigatons of ice per year since 2002.
Scientist at Potsdam Institute have found by modeling that for every five years climate forcing emissions are not reduced –as is happening at present– between 2020 and 2035, we could experience an additional 20 centimeters of sea level rise.
… humans are using up the world’s resources and causing distress to animals and plants on this planet at a staggeringly faster rate. At the same time, we are destroying our own civilization. In the end it all comes to the fact that we are overpopulated at 7.6 billion, which is projected to rise to 9.8 billion by 2050. What human society is doing at present is unsustainable and as a consequence we are mindlessly using up resources leaving little for our future generations. It is time we wake up and reverse our course.”
