Doctors Prescribing Nature

- Adam Clare

Doctor Robert Zarr prescribes walking in parks to his patients. Regular readers already know that the exposure to nature is beneficial in multiple ways for our physical and mental health. Doctors have also taken note of this and realize that prescribing walks and exposure to nature can reduce obesity rates while also being proactive in stemming other health problems.

Zarr doesn’t think prescribing parks is a radical step, though it may require a little getting used to. “Once you get over the conceptual hurdle of prescribing park, and you believe the scientific literature that clearly says being outside is good for health, then all it takes is to push a button on a computer. They have to do that anyway,” he says.

Zarr now hopes to develop a mobile app, and perhaps get the “have you been outside recently?” question included in patients’ pre-interviews alongside other vital signs queries.

Nature in One Cubic Foot

- Adam Clare

A portrait photographer has been travelling the world with a one cubic foot frame and cataloguing what’s in the area the cube covers. He has captured the value of biodiversity and along with science, notes that a bio-diverse farm is more productive and healthier than one that is focused on monocultural approach to crops.

There were 30 different plants in that one square foot of grass, and roughly 70 different insects. And the coolest part, said a researcher to the Guardian in Britain, “If we picked the cube up and walked 10 feet, we could get as much as 50 percent difference in plant species we encountered. If we moved it uphill, we might find none of the species.” Populations changed drastically only a few feet away — and that’s not counting the fungi, microbes, and the itsy-bitsies that Liittschwager and his team couldn’t see.
…

We need to feed our planet, of course. But we also need the teeny creatures that drive all life on earth. There’s something strange about a farm that intentionally creates a biological desert to produce food for one species: us. It’s efficient, yes. But it’s so efficient that the ants are missing, the bees are missing, and even the birds stay away. Something’s not right here. Our cornfields are too quiet.

Powering Tomorrow With Ancient Plant Technology

Photosynthesis is how plants convert energy from the ball of fire in the sky into useful plant-growing energy. The USA’s Department of Energy is actually looking into how photosynthesis can be used to power our homes and even turn homes into miniature power stations using the power of nature.

According to Nocera, his new system can work at ambient temperatures and pressures, without corrosion in a simple glass of water, even polluted water. “If you need pure water for energy storage, they’ll drink it,” Nocera said. “Use puddle water instead.” In fact, Nocera has been running his prototype on untreated water from the Charles River in Boston. And it’s cheap, not $12,000 per kilowatt like commercial electrolyzers that do the same thing. “That’s not going to help the energy situation for the U.S. or poor people of the world.”

Using the electricity generated by a photovoltaic array five meters by six meters, Nocera claims he can split enough water in less than four hours “to store enough energy for the average American home” for a day, a little more than 30 kilowatt-hours. “We need to stop making big energy systems one a time to service lots of people. We need to do it the old American way of making one small one and then manufacturing that system to give it to the masses.”

Time in Nature Makes People More Caring

- Adam Clare 1 Comment

This is good news for nature lovers and another reason to go outside and enjoy the world: the more time you spend experiencing nature makes you more caring.

Recent research suggests that spending time in nature actually makes people “more caring.” The studies, by University of Rochester psychologists Netta Weinstein, Andrew Przybylski, and Richard Ryan, showed that people exposed to nature (well, mostly slideshows of nature) put a higher value on intrinsic aspirations, such as doing good in the world or having meaningful relationships, and lower value on extrinsic aspirations, like making a lot of cash or admired by many people. Now as I mentioned, the participants didn’t actually live outdoors for a while or anything as part of the study. Rather, in three of the studies, they looked at images of either the built environment or landscapes and such. And in the fourth, some participants were assigned to work in a laboratory either with or without plants around them. Then they answered a series of questions or were given tests of generosity. “The result? People who were in contact with nature were more willing to open their wallets and share. As with aspirations, the higher the immersion in nature, the more likely subjects were to be generous with their winnings.”

Iron Current Turning Green

- Adam Clare

Here’s a really cool transition from a symbol of oppression to a symbol of growth and freedom: the old Soviet Iron Curtain has turned into a nature sanctuary. How cool is that?

But when its creators mark its 20th birthday this year, they will also be celebrating the fact that 23 European countries are currently engaged in a project to make it nearly five times as long. “The aim is to turn the Iron Curtain’s entire 4,250-mile length – extending from the Arctic to the Black Sea – into what is already being called the ‘Central European Green Belt’,” says Dr Kai Frobel, a German ornithologist and conservationist.

He was the man who started it all back in 1970s. In those days, it seemed impossible that the Berlin Wall might one day fall or that the Soviet empire could crumble. But that was almost irrelevant to Frobel, now a leading member of the German nature protection group, Bund, but then a teenager from the West German village of Hassenberg, which stood nearly in the Iron Curtain’s shadow. At 13, he was an enthusiastic birdwatcher. Equipped with a pair of pre-war Zeiss binoculars, a green army surplus parka, and heavy gumboots, he used to spend most of his free time in the hilly wooded countryside of his native northern Bavaria looking for new bird sightings, which he would record in his notebook.
…
An invisible trace is left by the last of the 1.3 million mines that used to litter the area. The vast majority were removed but the German authorities say they still cannot guarantee that all the Green Belt is completely mine-free. “This has its positive sides,” says Matthias Fanck, who is showing an exhibition on the Green Belt project in the former border town of Probstzella: “It means that tourists tend to stick to the paths and leave the nature reserve untouched.”

Twenty years on, the Green Belt has become an important part of Germany’s tourist industry. At strategic points along its route, visitors can call a free mobile phone number and listen to witnesses’ accounts of what the border once was. “It gives today’s generation of young Europeans an idea of what the Iron Curtain meant,” says Frobel.
