The West Antarctic Ice Sheet (about 2.2million cu.km, 10% of the total ice mass of Antarctica) has begun to collapse and may already have passed the point of no return. If all the ice in it will melt, sea levels will rise by about 4.6 m, and this may happen within the next few hundred years if greenhouse gas emissions continue to rise, flooding large coastal areas, coastal cities and even some cities far inland, such as Washington D.C.

Overfishing, effects of climate change such as acidification, pollution particularly by plastics, etc., threaten the health of our oceans. Effects will be on the world’s food supply, air quality, climate stability, etc. The Global Oceans Commission has outlined a “rescue package” including a limit to gas and oil exploration, capping subsidies for commercial fishing, and creating MPAs, marine protected areas.

What is largely responsible for all the mess? Our present economic system, in other words neoliberal capitalism with its overexploitation and little consideration of environmental impacts. See here:

However, why worry about all this, humans apparently cannot wait and are trying to speed things up even more.
Consider the recent attacks by some Muslim fanatics on the French satirical magazine Charlie and the reaction of Western governments to it. It seems that the proper reaction of the French government would have been to play things down and not up. But it did exactly the opposite, it played things up thus demonstrating “strength” to the electorate (President Hollande’s ratings went up by about 15%!!) and demonstrated to potential terrorists how to successfully challenge the west. It seems that the reaction was exactly what the terrorists wanted. Things were made even worse by millions of copies of the magazine with a cartoon of Mohammed on the front page distributed in various languages, causing uproar among muslims in many if not all countries (see attacks in Niger, planned attacks in Belgium, and the reaction of governments of various Muslim countries). Even the Pope, in strong terms, objected to the obvious insults against the Prophet and indeed any religion. – We are seeing, it seems to me, an ever increasing disregard for the rights of others, of the future of mankind, all in the name of short-term gains for the few who own the riches, and the political class which is trying to hold on to power whatever the long-term costs.
