Playing Pokémon Go? The internet has some advice for you.

By on Jul 15, 2016Share

Soon after Pokemon Go hit the App Store, reports started rolling in of the dumb lengths people have gone to in order to capture the little guys — like playing at the Holocaust Museum, Ground Zero, a funeral, or — more commonly — the middle of the street. Concerned about potential accidents caused by zombie-like trainers with their heads in their screens, the National Safety Council urged people to exercise caution playing the game. “No race to ‘capture’ a cartoon monster is worth a life,” wrote the Council. Clearly, they’ve never seen a Charizard.

Naturally, both players and haters alike took to Twitter to remind people to look up from their screens every once in awhile — and, for once, we recommend listening to them. And if you need a reminder, well, there’s an app for that, too.

Dogs Have Terrible Eyesight: See for Yourself

Sorry, C. M. Coolidge, but man’s best friend would probably really suck at poker. For one, dogs can’t see red. Two, their vision is so awful that they’d probably have trouble even making out the numbers.

See for yourself: WolframAlpha, every nerd’s favorite search engine, has a web app that lets you look at life through a dogs’ eyes.

Where people have three specialized receptors in our eyes to distinguish colors, dogs only have two: this leaves them red-green color blind (we think). Life’s Little Mysteries:

To see blue and yellow, dogs and humans alike rely on neurons inside the eye’s retina. These neurons are excited in response to yellow light detected in the cone cells (which are also inside the retina), but the neurons’ activity gets suppressed when blue light hits the cones. A dog’s brain interprets the excitation or suppression of these neurons as the sensation of yellow or blue, respectively. However, in dogs and color-blind individuals, red light and green light both have a neutral effect on the neurons. With no signal to interpret these colors, the dogs’ brains don’t perceive any color. Where you see red or green, they see shades of gray.

“A human would be missing the sensations of red and green,” Neitz told Life’s Little Mysteries . “But whether or not the dog’s sensations are missing red and green, or if their brains assign colors differently, is unclear.”

Aside from the color issue, dogs’ sight is pretty bad. Using a custom eye test for dogs, researchers have found that dogs basically have 20/75 vision compared to a person’s 20/20 vision, says Psychology Today.

To give you a feeling about how poor this vision is, you should know that if your visual acuity is worse than 20/40 you would fail the standard vision test given when you apply for a driver’s license in the United States and would be required to wear glasses. A dog’s vision is considerably worse than this.

Huge paper company promises to stop being deforesting jerks

Huge paper company promises to stop being deforesting jerks

Over the last 20 years, a third of the forest cover on the Indonesian island of Sumatra — home to endangered tigers and orangutans — was destroyed. The clear-cutting of the rainforest helped make Indonesia the world’s fourth-biggest carbon emitter. And much of it was done in the name of paper — Asia Pulp & Paper, to be exact. But not anymore. From The Washington Post:

Asia Pulp & Paper, the third-largest pulp and paper company in the world, announced Tuesday that it is halting operations in Indonesia’s natural rain forests, a victory for advocates who have been negotiating with the company for the past year.

The Singapore-based company, which controls logging concessions spanning nearly 6.4 million acres in Indonesia, said it also has agreed to protect forested peatland, which stores massive amounts of carbon, and to work with indigenous communities to protect their native land. …

Aida Greenbury, the firm’s managing director for sustainability, said that a coalition of environmentalists, customers and some of the firm’s own employees had pushed for an end to native forest logging.

“We heard very loud and clear what they want us to do,” she said. “It is an investment for the sustainability of our business, not only an investment in the environment and the social impact we’re creating.”

Here’s more from the righteous rabble-rousers at Greenpeace, who worked with the World Wildlife Fund and the Rainforest Action Network to shove APP’s clear-cutters out of the forests:

Today’s victory was an amazing milestone in a 40-country, ten-year campaign. In the U.S., Greenpeace and WWF cut over 75% of APP’s market, largely through persuading Mattel, Hasbro, Lego, K-Mart, Staples, Kroger, and other companies to cancel their contracts with APP or refuse to enter into business with the company. RAN topped it up, persuading Disney to dump APP as well. In total, over 100 companies pulled away from APP. APP struck back, forming front groups to attack Greenpeace and WWF for our work together.

So a deal is great news, right? Well, maybe. As The Washington Post notes, it all depends on APP’s ongoing level of commitment.

Christopher Barr, executive director of the U.S-based forestry research firm Woods and Wayside International, said people should approach “what APP does with a healthy dose of skepticism. They have a history of setting sustainability targets that either get pushed back or don’t get met.”

Barr noted the firm is seeking to build a third pulp mill in Sumatra.

When asked whether she believed the new policy would boost the firm’s chances of getting the permit, Greenbury replied, “We hope so,” but she added that the company was doing it for broader reasons.

“It is our intention to set a new benchmark for the pulp and paper mill industry globally,” she said

By not destroying pristine rainforest and habitat for endangered animals? That would be a new benchmark indeed, APP.
