Why unlocking cell phones is a green issue


People are talking a lot about cell phone unlocking in the news this week. Until recently, unlocking mostly flew under the radar—a common technique used by consumers who need to use their phones with more than one carrier. But late last year the Librarian of Congress banned the practice, catapulting cell phone unlocking into the national spotlight.
Unlocking is a software tweak that disables a device’s SIM lock. So, once the contract is over, owners of unlocked devices can switch to the carrier of their choice. Carriers including AT&T and Verizon argue that unlocking a cell phone without permission is a violation of copyright under the 1998 Digital Millenium Copyright Act—a law originally designed to prevent piracy. For the past three years, cell phone unlocking has been exempted from the DMCA. When the Librarian of Congress lifted the exemption, he made it illegal to unlock a phone.
Immediately after the ban took effect on January 26, the internet lit up in protest. Digital rights activists and personal property proponents mobilized forces, and a petition on We the People—the White House’s official petitioning forum—garnered the support of thousands. Their demand: legalize cell phone unlocking.
On Monday, the fervor prompted a White House response. In no uncertain terms, the administration backed legalizing the unlocking of both cell phones and tablets.
“It's common sense, crucial for protecting consumer choice, and important for ensuring we continue to have the vibrant, competitive wireless market that delivers innovative products and solid service to meet consumers' needs,” wrote R. David Edelson, the White House’s senior advisor on the internet.
And while cell phone unlocking is absolutely an issue of consumer and digital rights, something important has been ignored in this conversation: unlocking also a green issue. 426,000 cell phones are decommissionedevery single day in the United States; many of them will end up banished to junk drawers and rotting in landfills. One billion cell phones are sitting idle in drawers and closets, losing value while they are waiting to be put back into service.
Swapping old phones is a common practice; just this week my brother borrowed an old phone from me after his failed. The catch? Swapping only works if you both use the same carrier—an artificial limitation that has created a huge barrier to a sharing economy. Re-legalizing unlocking will keep more devices in service and out of the national waste stream.
Cell phones and the environment
Wireless technology is a big business in the United States. There are more wireless devices in the US than there are people. As of late 2012, Apple had sold more than 85 million iPhones and 34 million iPads. To date, Samsung has produced 800 million mobile phones. Those numbers grow every single day—and that has environmental consequences.
Electronics manufacturing isn’t a clean industry. A single cell phone houses within it over half of the elements on the period table—many of which can’t be recovered in recycling. Pit mining—fueled by the demand for more electronics—is savaging the environment, causing water pollution that leads to birth defectsConflict minerals, like coltan, are required to make every single cell phone—and warlords use mining profits to fund conflicts that tear apart places like the Democratic Republic of the Congo.
Beyond the harmful effects of conflict minerals, there’s the very real threat of e-waste. Every year, the world tosses out between 20 to 50 million metric tons of electronics—only 18% of which is recycled. As a result, e-waste is piling up in landfills around the world. The more electronics we consume, the worse the problem gets.
How can unlocking help?
The best shot we have of stemming the environmental damage caused by electronics manufacturing is to make our gadgets more reusable. Unlocking is part of that solution. The average cell phone customerchanges carriers every 4 years. Locked devices can’t travel from carrier to carrier, so—even if fully functioning—they become obsolete with every carrier switch. It’s all too easy to throw obsolete devices into the trash: only 8 percent of cell phones are recycled.
Reuse is key to extending the life of electronics. Let’s take a lesson from free market economics: the larger the potential market, the more value your product has. While locked phones can only be sold to people who have the same carrier, unlocked phones have a bigger market and hold more value over time, sometimes doubling or tripling the resale value of a device. Moreover, refurbishers need to unlock cell phones in order to sell them to new users. Unlocking means a phone lives beyond the first user to the second, third, and fourth. And the longer electronics stay in service, the less demand there is to manufacture more.
Taking away our right to unlock our phones isn’t about protecting creative work through copyright; it’s about protecting corporate profit at the expense of the consumer and the environment. The White House supports restoring our right to legally unlock our phones and, right now, Congress is listening.
Happy Unlocking guys

Orphaned tiger given goat to eat, befriends it instead


In 2009, a Bengal tiger cub was rescued from India's Dhaba forest range, left helpless after the disappearance of its mother. Over the next few years, keepers at the Bor Wildlife Sanctuary raised the orphan, named Bhangaram, to adulthood in hopes of one day releasing him back into the wild.
But, as it turns out, not only was the tiger out of the jungle, the jungle seemed to be out of it.
Staff at the wildlife sanctuary recently released a live goat into the now full-grown male tiger's enclosure as a way of triggering its predatory instincts. However, as opposed attacking the helpless animal, the unusually docile tiger did quite the opposite.
From the Times of India:
[Keepers had] hoped the beast would make a quick kill. To their astonishment and horror, the tiger instead decided to make friends with its intended meal. For two days, the tiger did not kill the goat despite being hungry. Instead it played with it; at one point even playfully dumping it in an artificial waterhole. Finally, the goat was shifted out and the tiger was given beef to eat.
Although the thought of a normally ferocious tiger 'befriending' its intended meal might seem like an adorable turn for the predator, conservationists say there is nothing cute about the big cat's unwillingness to kill. In fact, Bhangaram's temperate behavior may mean he will never be reintroduced to the wild where tiger numbers are in decline.
.
"I fear the male tiger is not fit for release," says veteran conservationist MS Chouhan
Since the early 1970s, the Indian government has established wildlife sanctuaries and rehabilitation centers in hopes preserving Bengal tigers, driven to near extinction from poaching and other conflicts with humans. But, as conservationists have learned, when young cubs are rescued after the loss of their mother, they often lack the hunting skills only she can teach them.
Sadly, even once rescued tigers are returned to the wild, they are more prone to the same violent run-ins with humans that may have befallen their parent. Tiger experts say that animals which have lived in captivity are more likely to prey on cattle, which in turn puts them at risk of being killed by farmers. In other words, the loss of even a single tiger can have ramifications lasting for generations.
Despite these challenges, conservationists have reported that the number of tigers in India has increased by over 15 percent in recent years. All told, however, tiger populations throughout the world have dropped 96.8 percent over the last two decades from poaching and habitat loss.

New infrared camera detects greatest cause of acid rain


 A new infrared camera technology can detect and measure major pollutants like sulfur dioxide, which is the greatest cause of acid rain. The pollutants, which also include CO, NOx, SF6, hydrocarbons and more, are usually invisible to the human eye, but the technology is able to detect them and measure their individual concentrations because they each have a unique infrared signature.
The Universidad Carlos III de Madrid's Laboratorio del Infrarrojo (LIR)developed the camera and says it's better than other devices that exist for detecting these compounds because it can measure them individually in a mix and it can do so from hundreds of meters away and in real time, none of which is possible with any of the other instruments available today.
The camera can be used to detect these pollutants from things like highly polluting vehicles, power plants or industrial chimneys. Especially in industrial and energy production settings, the camera could serve as a monitoring device.
"They can be installed and easily handled by workers in all kinds of factories or industries and can even be part of a permanent monitoring system that automatically activates an alarm when it detects the leak of a specific gas, such as SO2", says the CEO of SENSIA Solutions, a spin-off of the laboratory that has patented the device. "The cost of these systems would not be greater than that of any classic infrared camera, although it may vary based on certain parameters, such as the required detection distance, the concentration or expected time of the gas, among other factors."
The camera could automatically detect leaks or excessive emissions so that companies could make necessary changes to get the pollution in check.
For vehicles, the university says that "studies have shown that only a small proportion of the motor pool is responsible for most of the polluting emissions that are produced by automobiles. Therefore, to reduce the pollution caused by transportation, it is essential to detect and control the offending vehicles; this new generation of infrared cameras could play an important role in this task."
"Due to the device's extreme sensitivity, it is possible to detect even very low levels of emissions, and it can be adapted to the new legal limits that may be set for new models of automobiles in the future," says Miguel Ángel Rodríguez, an LIR scientist.
In India, China and Japan, acid rain is a significant problem due to the fact that the region has the highest amount of SO2 pollution in the world. When moisture in the air mixes with SO2 and nitrogen oxides (both detected by the camera), resulting precipitation comes down as acid rain, which can have major negative impacts to aquatic life, vegetation and corrode marble and limestone infrastructures.
Having technology that can accurately detect and measure these types of pollutants is the first step to being able to stop them at the source.
