China Is Ending Its "One-Child Policy" - Here Are The Implications | Zero Hedge

China Is Ending Its "One-Child Policy" - Here Are The Implications | Zero Hedge | General geography |
Back in 1978, the Chinese politburo enacted the "one-child policy", whose main purpose was to "alleviate social, economic, and environmental problems" in China as a result of the soaring population.

A Historian’s Take on Food and Food Politics...


This brief article highlights that as much as technology has changed food production, there this is much more that has remained the same.  Of the thousands of plants on Earth, 11 account for most of what we eat (corn, rice, wheat, cassava, potatoes, sorghum, millet, beans, barley rye and oats) .  Not surprisingly, those 11 plants are the same that have been cultivated by humans for thousands of years--makes you think that early humans, while not technologically advanced, were constantly conducting agricultural experiments and found many of the best animal and plant resources for human consumption.  This is one reason losing local indigenous knowledge about cultural ecology and the species' genetic diversity would be a great loss for humanity.

Kyle Patchett's curator insight, September 2, 2016 4:20 AM
This article explains in an emotive fashion that humans as a species aren't as diverse as first thought. The author, Rachel Laudan, explains that even as technology and food production has changed, much remains the same. There are on average 20,000 plants that are edible to humans, yet there are 11 plants that provide a steady diet for 93% of the worlds' population. These plants have been part of our diet for thousands of years and since the birth of farming itself. The article is produced from a food historians' point of view on the matter of change that we as a species have made. The information shows that even as technology, agriculture and farming has expanded, we have just found ways to do the same thing but slightly better than we previously had done.

These Crazy Maps Show The Unequal Cause And Effect Of Climate Change

These Crazy Maps Show The Unequal Cause And Effect Of Climate Change | General geography |


Climate change is a fundamentally unfair phenomenon. For one thing, the countries that have contributed most to atmospheric build-ups of CO2 won’t bear the brunt of the consequences. For another, the people who are least equipped to deal with climate shocks--through adaption and health care services--are likely to be most vulnerable. It’s an unequal world.


To get an immediate graphical sense of this, take a look at these excellent cartograms--maps that are distorted to reflect certain data. See, for example, the difference when you compare a standard world map (or ones resized for population or wealth), and then for historical emissions (1850–2007), or consumption (all products and services). Or the difference between countries’ wealth and the risks their people face. (See all the data sources here).
