Don’t say climate change, prefer ” climate crises “

Global warming could lead to more violence and warsTo a recent study, global warming could cause a 50 percent increase in violent conflict. Given that it has already sparked the matches of war in Darfur and Syria, one can be scared.  As the Guardian noted :

” A group of researchers have trawled the scientific literature and concluded from 60 studies, from Somalia and China to Colombia and the Middle East, that unusually warm weather generates more aggression and conflict.

” In parts of equatorial Africa, they suggest, every added degree of heat increases the chance of conflict between groups by 11 to 14%. “

Here come the toilets of the future

Here is a smelly question : why are we putting together what Nature separates ? This is the question asked by a Swedish researcher about toilets. Putting urine and feces together is not a good idea as it is simply a waste of resources.

Moreover, flushing with liters and liters of perfectly drinkable water is a bad idea as water scarcity is already striking around the world and will spread as climate gets warmer.

Now here come scientists from Singapore with an idea that could revolutionize the way we dispose from our bodily waste.

Seven billion souls on Planet Earth

To Echo Sierra : ” According to the UN Population Fund, the global population will reach 7 billion souls on the 31st of October 2011, giving concerns about the natural resources scarcity and inequalities a renewed and actual acuity.”

” According to UN estimates, world population could grow to 15 billion by the end of the century, while global economy is based on limited  – and thus craved – resources. Conditions are met for an escalation of tensions and conflictuality.” 

I personally believe that it will prove difficult to reach even nine billion people as climate gets warmer and weirder. Olivier is absolutely right in saying that we will face an escalation of tensions…

A great idea for tiny apartments

In the age of scarcity, space can be a very expensive commodity. Hong Kong architect Gary Chang had an awesome idea to solve this : he transformed his 32 square meters appartment into a much bigger one with sliding walls.

This very simple yet ingenious idea allows him to have in a relatively secluded place many different rooms such as a library, a full kitchen, a bathroom with a tub and a spare bedroom. He even has a laundry room !

As you can imagine such a creative idea has travelled all around the world and Mr. Chang’s appartment was featured in the New York Times, the AFP and TreeHugger.

Worsening water scarcity crises in China

water-in-chinaI was reporting last week that many countries in South Asia are facing water scarcity. And to recent articles I read, it seems that the phenomenon is also witnessed in China as well, but an even more worrying way.

An article from the Green Leap Forward brings us great information on that worsening trend. This coupled to the economic turmoil creates a potentially explosive situation in rural China, as 20 million people are going back.

The situation was already critical last year when I first wrote about that topic, but what I read really makes me believe that Jared Diamond was right on China.
