Israel Proves the Desalination Era Is Here

Israel Proves the Desalination Era Is Here | :: The 4th Era :: | Scoop.it
One of the driest countries on Earth now makes more freshwater than it needs

 

Driven by necessity, Israel is learning to squeeze more out of a drop of water than any country on Earth; researchers have pioneered new techniques in drip irrigation, water treatment and desalination. “The Middle East is drying up,” says Osnat Gillor, a professor at the Zuckerberg Institute who studies the use of recycled wastewater on crops. “The only country that isn’t suffering acute water stress is Israel.” That water stress has been a major factor in the turmoil tearing apart the Middle East, but Bar-Zeev believes that Israel’s solutions can help its parched neighbors, too — and in the process, bring together old enemies in common cause.

This connects to the physical geography of Israel as it was once incredibly dry, facing a decade long drought. This ruined the agriculture sector of their economy as well, along with changing the people's way of life. However, desalination has saved the country, and Israel really had no other choice. Instead, the country is now a water giant, and has an overabundance through new technologies.

When China Rules the Sea

When China Rules the Sea | :: The 4th Era :: | Scoop.it
The United States is no longer the world’s only global naval power.


Why would China go to the trouble and expense of mounting an expedition to the northern climes in the Western Hemisphere? Because it sees value in staging a presence in distant waters. And because it can: Beijing no longer depends completely on its oceangoing battle fleet to ward off threats in China’s seas. It can now rain long-range precision firepower on enemy fleets from land. Ergo, the People’s Liberation Army Navy (PLAN) fleet can cruise the far reaches of the Pacific and Indian oceans or even beyond, without forfeiting China’s interests in waters close to home.  For China, the upsides of far-ranging maritime strategy are many and compelling, the downsides fewer and fewer.

The nation that controls the seas, controls the world. Throughout history the leading Naval powers have always been the worlds most dominate nations. The greatest land forces, are no match for the supremacy of the seas. Not even Napoleon could beet back the power of a supreme navy( The British Royal Navy). Since the end of the Second World War, The United States navy has dominated the seas. That domination has made the U.S the worlds greatest nation over the course of the past 75 years. For China to displace the U.S atop the nations hierarchy, they most out due us on the seas. China is ware of this history, and that is why they are heavily investing in their naval technology. The key to the future, as it has been in the past, will be what nation can dominate the worlds seas.

Benjamin Jackson's curator insight, December 13, 2015 8:23 AM

the growing strength of the Chinese navy is worrying from a military perspective, as during the cold war one of the main reasons they were not considered as big a threat as the Russians was because of their inability to project force beyond mainland china. with their navel improvements this is no longer the case. what this will hold for the future, we can only wait and see.

Climate change has already displaced tens of thousands of people. If it continues unabated, it could lead to one of the largest mass human migrations in history.
