Extreme poverty has fallen below 10 per cent of the world’s population for the first time...Global inequality has been plunging as Africa and Asia experience faster economic growth than Europe and North America; child mortality has fallen to record low levels; famine virtually went extinct; malaria, polio and heart disease are all in decline.
...we are getting more sustainable, not less, in the way we use the planet...some nations are beginning to use less stuff: less metal, less water, less land. Not just in proportion to productivity: less stuff overall...what if economic growth means using less stuff, not more?’ For example, a normal drink can today contains 13 grams of aluminium, much of it recycled. In 1959, it contained 85 grams. Substituting the former for the latter is a contribution to economic growth, but it reduces the resources consumed per drink...The quantity of all resources consumed per person in Britain (domestic extraction of biomass, metals, minerals and fossil fuels, plus imports minus exports) fell by a third between 2000 and 2017, from 12.5 tonnes to 8.5 tonnes. That’s a faster decline than the increase in the number of people, so it means fewer resources consumed overall.
Mobile phones have the computing power of room-sized computers of the 1970s. I use mine instead of a camera, radio, torch, compass, map, calendar, watch, CD player, newspaper and pack of cards. LED light bulbs consume about a quarter as much electricity as incandescent bulbs for the same light...Even in cases when the use of stuff is not falling, it is rising more slowly than expected. For instance, experts in the 1970s forecast how much water the world would consume in the year 2000. In fact, the total usage that year was half as much as predicted. Not because there were fewer humans, but because human inventiveness allowed more efficient irrigation for agriculture, the biggest user of water.
...despite the growing number of people and their demand for more and better food, the productivity of agriculture is rising so fast that human needs can be supplied by a shrinking amount of land...we use 65 per cent less land to produce a given quantity of food compared with 50 years ago. By 2050, it’s estimated that an area the size of India will have been released from the plough and the cow.
Since its inception, the environmental movement has been obsessed by finite resources. The two books that kicked off the green industry in the early 1970s, The Limits to Growth in America and Blueprint for Survival in Britain, both lamented the imminent exhaustion of metals, minerals and fuels. The Limits to Growth predicted that if growth continued, the world would run out of gold, mercury, silver, tin, zinc, copper and lead well before 2000...To this day none of those metals has significantly risen in price or fallen in volume of reserves, let alone run out.
A modern irony is that many green policies advocated now would actually reverse the trend towards using less stuff. A wind farm requires far more concrete and steel than an equivalent system based on gas. Environmental opposition to nuclear power has hindered the generating system that needs the least land, least fuel and least steel or concrete per megawatt.
As we enter the third decade of this century, I’ll make a prediction: by the end of it, we will see less poverty, less child mortality, less land devoted to agriculture in the world. There will be more tigers, whales, forests and nature reserves. Britons will be richer, and each of us will use fewer resources. The global political future may be uncertain, but the environmental and technological trends are pretty clear — and pointing in the right direction.
