When electronics end up in landfills, toxics like lead, mercury, and cadmium leach into the soil and water.
The electronic waste problem is huge: More than 20 million tons of e-waste are produced every year. Americans alone generate about 3.4 million tons of e-waste per year. If you put every blue whale alive today on one side of a scale and one year of US e-waste on the other, the e-waste would be heavier.
Some e-waste is shipped overseas, where it is burned for scrap by kids in junkyards. We visited a scrapyard in Accra, Ghana and met some really good kids in a bad situation. They didn’t know how toxic their job really is.
Even so, encouraging a global market for used electronics does more good than harm: 1.Repaired electronics give people access to low-cost electronics and help them access the awesome benefits of technology 2.Used electronics create repair jobs in developing countries that often have few opportunities for skilled labor 3.Reuse in developing countries is usually more effective than domestic recycling—there’s not much of a market for old cathode ray tube monitors in the US, for example, but they are reused in other countries.
Global consumption of electronics is increasing. Every year we create more e-waste than before. At least 50% of Africa’s e-waste comes from within the continent. China discards 160 million electronic devices a year.
We create too much e-waste and reuse way too little.
Humanity has reached its peak and is now probably in its downfall, according to major new research.
People have long thought of human development as one long process of improvement, going on forever. But we are now running up against the limits of how good we can be, say scientists – and most likely we'll now just begin to fall again.
人類はピークに達して、現在文明のレベルは後退を始めている。
The major research review looked at 120 years of data and found that there appears to be limits on our characteristics, like when we die, how tall we can be and how strong we are. We are pushing up against those limits now, the research suggests.
What's more, the ways that we are changing our environment – including through global warming – is probably going to pull those limits down and force humanity into a decline, the researchers said.
For a long time, humanity has looked to be improving. Sprinting speeds that once seemed impossible are now commonplace, for instance, and the record for oldest person in the world is often being broken.
But with time, we'll probably see fewer world records being broken, the new research suggests, and little development in how old the oldest people are. More people might reach those peaks of performance, but the peaks will get no higher, the research published in the journal Frontiers in Psychology found.
"These traits no longer increase, despite further continuous nutritional, medical, and scientific progress. This suggests that modern societies have allowed our species to reach its limits. We are the first generation to become aware of this" said Jean-François Toussaint from Paris Descartes University, France.
Some of those limits now appear to be falling. And it is in large part because of changes we are making to our environment, said Professor Toussaint.
"This will be one of the biggest challenges of this century as the added pressure from anthropogenic activities will be responsible for damaging effects on human health and the environment." he said in a statement. "The current declines in human capacities we can see today are a sign that environmental changes, including climate, are already contributing to the increasing constraints we now have to consider.
"Observing decreasing tendencies may provide an early signal that something has changed but not for the better. Human height has decreased in the last decade in some African countries; this suggests some societies are no longer able to provide sufficient nutrition for each of their children and maintain the health of their younger inhabitants."

After his own defection to South Korea in 2010, Choi Seong-guk, 37, realized that the two Koreas were no longer the same country — many cultural and linguistic differences have arisen during more than 70 years of division.
