The Great Barrier Reef was not bleached naturally

The Great Barrier Reef was not bleached naturally | ApocalypseSurvival | Scoop.it

"This year, we’ve seen alarming bleaching of the Great Barrier Reef, caused by warm sea temperatures. A recently completed aerial survey of the reef found that 93 percent of the smaller reefs that comprise it showed at least some bleaching, and in the northern sector of the reef, the large majority of reefs saw bleaching that was severe — meaning many of these corals could die.  There was already considerable murmuring that this event, which damages a famous World Heritage site and could deal a blow to a highly valuable tourism industry, did not simply happen by chance. And now, a near real-time analysis by a group of Australian climate and coral reef researchers has affirmed that the extremely warm March sea temperatures in the Coral Sea, which are responsible for the event, were hardly natural."

What would happen if humans became extinct?

What would Earth be like if all humans suddenly disappeared? This question posed on the YouTube series Earth Unplugged, has many intriguing ecological and biogeographic ramifications that are worth considering to explore how systems are interconnected.

I find this youtube video interesting but for sure, the planet has become very interconnected with humans but that has not been a postiive effect. Humans have done nothing but manipulate the natural order of the ecosystem. If humans went extinct I would assume the earth would balance its self out.

Norka McAlister's curator insight, January 27, 2015 7:50 PM

It is funny because this video just made me think about TV shows such as The Walking Dead and Z-Nation.  Of course, not for the zombies, but what if some disease might wipe out the human race, and also how the earth will looks like after human extinction. The impact on earth when human life is gone will be catastrophic for domestic animals left behind. The wild animals will become dominant. Many species will also become extinct and a lot of chemicals will poison grounds and infrastructure will collapse with the force of the weather after few years. Although, it is fascinating how humans can preamble the fact that satellite can be worked forever after humans are gone from Earth. It is not only about humans, but also about the Earth that we need to come up with more reasons to be green on the planet.

Peak Water in the American West

Peak Water in the American West | ApocalypseSurvival | Scoop.it

First, we must acknowledge that we’ve reached peak water in the American west. We have promised more water to users than nature provides. Until demand and supply are brought back into balance, groundwater levels will continue to drop and our rivers will continue to run dry, destroying natural ecosystems. Second, we must acknowledge that there are limits to new supply and that we must turn to the demand side of the problem. This means figuring out how to use water more efficiently and productively, and thinking about moving some water-intensive activities and products to more water-abundant regions. Maybe it is time to grow less rice, alfalfa, cotton, and pasture with flood irrigation. It is past time to retire the green lawn as an acceptable landscape option in arid climates. All toilets and washing machines should be water- and energy-efficient. Finally we have to stop assuming that the water available for future use is the same as in the past. Climate change ensures that it won’t be, but until politicians start to heed the warnings of climate scientists and the on-the-ground evidence of the current water situation, our water problems in the west, and elsewhere, will worsen.

You Built What?!: A Tractor For The Apocalypse

You Built What?!: A Tractor For The Apocalypse | ApocalypseSurvival | Scoop.it

Marcin Jakubowski didn’t study fusion physics to become a farmer. But the Polish-American scientist grew more disillusioned with academia the longer he worked toward his doctorate. Researchers withheld data to compete for grants, he says, instead of collaborating to solve big problems. “The further I went in my Ph.D. program, the less value I felt I was contributing to society,” he says. Seeking a fresh start, Jakubowski bought 30 acres of Missouri farmland and a tractor. Life in relative seclusion proved uneventful until, one day in 2008, his tractor broke down for the second and last time, spurring him to start an open-source industrial revolution.

To Jakubowski, the tractor seemed designed to fail. Why should he sink more money into fixing it or buy a replacement? He wanted a simple and useful machine, and one he could repair and upgrade on the fly. “It boiled down to lower cost in the long run,” he says.

Jakubowski built the first LifeTrac, as he calls his DIY tractor, in three months for $6,000—about $30,000 less than a comparable mass-produced model. Seeing room for improvement, he built a second prototype in just six days. He posted his progress on the tractor and other machines to an online wiki, which attracted followers, who suggested their own design tweaks. Some even visited in person to help with builds—and Open Source Ecology took off.

It's official: a global mass extinction is under way

It's official: a global mass extinction is under way | ApocalypseSurvival | Scoop.it

"New research confirms that the next mass extinction is in progress, and we’re the cause. There’s been little doubt that humans have been severely altering the planet and reducing biodiversity, but it has been unclear how many species go extinct under normal circumstances, without human influence.

This new research clarifies the rate of 'background extinction' (the rate of extinction during the point before humans became a primary contributor to extinction). The research confirms that human activity is driving species extinct at a rate far higher than the background rate. A look at previous events suggests cause for concern. Geologists recognize five previous mass extinction events— the end of the Ordovician, Devonian, Permian, Triassic, and Cretaceous periods, meaning that we’re now in the 6th."

Are There Any Regions of the Country That Will Escape Effects of Climate Change? | UCSUSA

Are There Any Regions of the Country That Will Escape Effects of Climate Change? | UCSUSA | ApocalypseSurvival | Scoop.it
My husband and I live in the American Southwest and are very concerned about its habitability in the future due to worsening drought and rising temperatures. We are especially concerned about where our children and grandchildren will be able to live and prosper. Are there any regions of the country that might emerge unscathed from the effects of climate change?

Jess Deady's curator insight, April 30, 2014 8:36 PM

The Aral Sea Basin has been a topic of conversation throughout geography for many reasons. What used to be filled with water is now blowing dust because its that dry? This basin is no longer a natural resource.

Gene Gagne's curator insight, November 18, 2015 3:30 PM

Here is a question. Do you think perhaps in the future this could happen to lake Mead in Nevada/Arizona? With all the non-stop building and no rain perhaps one day could it run dry or do we have a way to stop it.

Gene Gagne's curator insight, December 1, 2015 7:17 PM

Once there is less water in a lake there is less water in the air therefore less rain. The long term consequences is that the fishing industry is destroyed where once upon a time there were 61000 workers and now there are under 2000. The water is more saltier. The lands are now ill suited and unbuildable. Also the people there are prone to health problems.

SAN FRANCISCO — For generations, the Maya thrived in an advanced, complex civilization in modern-day Central America. But then their society collapsed in the eighth and ninth centuries.
