It has taken a very long time for politicians to accept the obvious with respect to climate change. We must remember that, in our democratic system, politicians are elected by all of us to represent us and this is probably the main reason why they will never tackle any problem which requires a solution that creates even a small hardship for the majority of us. They fear, rightly so, that they will fail to be re-elected.
There are several of these unpopular issues which are pushing our world towards the point of not being able to sustain human life. These are 'Growth' factors, most of which are paradoxically looked at as increasing our quality and enjoyment of life. Population, economy, consumerism, jobs, wealth, all these have been looked at as being able to grow continuously and without end. Believing this is obviously even more ridiculous than denying the effects of climate change.
During my lifetime, world population has tripled from just over 2 billion to 6.5 billion. During that time, the earth has not become any bigger and, in fact, the basic resources which sustain life, arable land, drinkable water, oxygen producing plants, have all been decreasing. It seems obvious that we have already passed the point of sustainability and that only 2 strategies will help: population reduction, preferably by reducing the birth rate to below the death rate for the foreseeable future, or, reducing the world standard of living to subsistence level while holding the population steady and apportioning the existing resources evenly amongst all people.
Although this may sound like a 'socialist scheme to suck money out of wealth-producing countries', I see it as a last ditch effort to produce a soft landing to the end of the capitalist dominated world order. Those of us fortunate enough to live in the 'wealth-producing countries' will probably feel the results of non-action even more that those who are currently at an economic disadvantage.
One of the most likely mechanisms for uncontrolled population reduction would be a massive pandemic and pandemics would be felt much more quickly by the travelers from the developed world than by nomads or villagers. In any case, such massive and uncontrolled depopulation would cause a complete breakdown of order and infrastructure throughout the world so no one would escape the chaos, anarchy and destruction.
Perhaps we should be looking for politicians who are touting 'population shrinkage', 'economic decline' or 'wealth redistribution'. Get out on the street now and campaign before governments start to rebuild the mental health institutions they closed to save your money. While they have now found that there is no where to put so many of the homeless and addicted who have mental health problems, there is also no where for them to put you, so you just might be able to get your message out without disappearing. Lots of luck.
