Population growth is a threat. But it pales against the greed of the rich

George Monbiot writing in The Guardian raises a critical question and issue:

"I cannot avoid the subject any longer. Almost every day I receive a clutch of emails about it, asking the same question. A frightening new report has just pushed it up the political agenda: for the first time the World Food Programme is struggling to find the supplies it needs for emergency famine relief. So why, like most environmentalists, won't I mention the p-word? According to its most vociferous proponents (Paul and Anne Ehrlich), population is "our number one environmental problem". But most greens will not discuss it.

Is this sensitivity or is it cowardice? Perhaps a bit of both. Population growth has always been politically charged, and always the fault of someone else. Seldom has the complaint been heard that "people like us are breeding too fast". For the prosperous clergyman Thomas Malthus, writing in 1798, the problem arose from the fecklessness of the labouring classes. Through the 19th and early 20th centuries, eugenicists warned that white people would be outbred. In rich nations in the 1970s the issue was over-emphasised, as it is the one environmental problem for which poor nations are largely to blame. But the question still needs to be answered. Is population really our number one environmental problem?

The Optimum Population Trust (OPT) cites some shocking figures, produced by the UN. They show that if the global population keeps growing at its current rate, it will reach 134 trillion by 2300. But this is plainly absurd: no one expects it to happen. In 2005, the UN estimated that the world's population will more or less stabilise in 2200 at 10 billion. But a paper published in Nature last week suggests that there is an 88% chance that global population growth will end during this century.

In other words, if we accept the UN's projection, the global population will grow by roughly 50% and then stop. This means it will become 50% harder to stop runaway climate change, 50% harder to feed the world, 50% harder to prevent the overuse of resources. But compare this rate of increase with the rate of economic growth."

Reading the Chilcot Inquiry Report more closely

Most commentary on the Chilcot Inquiry Report of and associated with the Iraq War, has been "lifted" from the Executive Summary.   The Intercept has actually gone and dug into the Report, with these revelations : "THE CHILCOT REPORT, the U.K.’s official inquiry into its participation in the Iraq War, has finally been released after seven years of investigation. Its executive summary certainly makes former Prime Minister Tony Blair, who led the British push for war, look terrible. According to the report, Blair made statements about Iraq’s nonexistent chemical, biological, and nuclear programs based on “what Mr. Blair believed” rather than the intelligence he had been given. The U.K. went to war despite the fact that “diplomatic options had not been exhausted.” Blair was warned by British intelligence that terrorism would “increase in the event of war, reflecting intensified anti-US/anti-Western sentiment in the Muslim world, including among Muslim communities in the

An unpalatable truth!

Quinoa has for the last years been the "new" food on the block for foodies. Known for its health properties, foodies the world over have taken to it. Many restaurants have added it to their menu. But, as this piece " Can vegans stomach the unpalatable truth about quinoa? " from The Guardian so clearly details, the cost to Bolivians and Peruvians - from where quinoa hails - has been substantial. "Not long ago, quinoa was just an obscure Peruvian grain you could only buy in wholefood shops. We struggled to pronounce it (it's keen-wa, not qui-no-a), yet it was feted by food lovers as a novel addition to the familiar ranks of couscous and rice. Dieticians clucked over quinoa approvingly because it ticked the low-fat box and fitted in with government healthy eating advice to "base your meals on starchy foods". Adventurous eaters liked its slightly bitter taste and the little white curls that formed around the grains. Vegans embraced quinoa as

Climate change: Well-organised hoax?

There are still some - all too sadly people with a voice who are listened to - who assert that climate change is a hoax. Try telling that to the people of Colorado who recently experienced horrendous bushfires, or the people of Croatia suffering with endless days of temps of 40 degrees (and not much less than 30 at night time) some 8-10 degrees above the norm. Bill McKibben, take up the issue of whether climate change is a hoax, on The Daily Beast : Please don’t sweat the 2,132 new high temperature marks in June—remember, climate change is a hoax. The first to figure this out was Oklahoma Senator James Inhofe, who in fact called it “the greatest hoax ever perpetrated on the American people,” apparently topping even the staged moon landing. But others have been catching on. Speaker of the House John Boehner pointed out that the idea that carbon dioxide is “harmful to the environment is almost comical.” The always cautious Mitt Romney scoffed at any damage too: “Scientists will fig
