Could 3D printing end our throwaway culture?

Could 3D printing end our throwaway culture?

There's a tiny knob missing from my hands-free car kit, which I keep meaning to replace. The thing is, I don't think I can buy parts for it, so I probably need to fork out for a whole new system, which, frankly, I'm reluctant to do. Sound familiar? How many broken thingamajigs do you have around your home – and how many items have you chucked out with the rubbish?

Mixed messages on climate 'vulnerability'

Mixed messages on climate 'vulnerability'


One of the most striking new voices on climate change that's emerged since the UN summit in Copenhagen two years ago is the Climate Vulnerable Forum.
The grouping includes small island states vulnerable to extreme weather events and sea level rise, those with immense spans of low-lying coastline such as Vietnam and Bangladesh, and dry nations of East Africa.
It's currently holding a meeting in Bangladesh, with UN Secretary-General Ban Ki-moon as the keynote speaker.

Hooking fish, not endangered turtles Novel tuna-fishing gear may avoid unintended avian and turtle casualties

Hooking fish, not endangered turtles Novel tuna-fishing gear may avoid unintended avian and turtle casualties

A tuna fisherman has taken it upon himself to make the seas safer for sea turtles, animals that are threatened or endangered with extinction worldwide. He’s designed a new hook that he says will make bait — and the lethal barb that secures it — unavailable to marine birds and turtles until long after it’s sunk well below the range where these animals venture to eat.

Environmental projects get more than half a billion dollars

For once, there is good news for the environment: a flurry of international conservation initiatives and environmental research projects were given the green light last week. They were backed with more than half a billion US dollars in grants from the Global Environment Facility (GEF) in Washington DC, the world’s largest funder of environmental projects.

World's Largest Dam Removal Set to Restore Ecosystem

Link: World's Largest Dam Removal Set to Restore Ecosystem

The world’s biggest dam removal project — and the second-largest environmental restoration project in U.S. history — is in progress on the Elwha River on the Olympic Peninsula in Washington state.


The Elwha Dam and the Glines Canyon Dam blocking the Elwha River are coming down due to aging infrastructure and as part of an effort to restore fish runs. When the dams were built in the early 1900s to provide hydroelectric power to nearby residents, they were installed without a way for fish to pass. Ever since, prime habitat upstream on the Elwha has been inaccessible to salmon.

If You Act Your Age, What’s Your Carbon Footprint?

Link: If You Act Your Age, What’s Your Carbon Footprint?

We’ve all heard that some countries produce more carbon dioxide per capita than others, with the United States among the leaders of the pack. But how do your individual emissions change over the course of a lifetime? As it turns out, if you’re enjoying senior citizen discounts, you’re probably much kinder to the planet than you were in your slightly younger days, but your 20-something grandchildren are kinder still.

Thawing microbes could control the climate

Link: Thawing microbes could control the climate

As the Arctic permafrost melts over the coming decades, long-frozen microorganisms will thaw out and start feasting on the soil. The first have already begun to wake up – and early signs are that they will have a major impact on how Earth’s climate changes.

Gravestone Project

The weathering rates of gravestones are an indication of changes in the acidity of rainfall between locations and over time. The acidity is affected by air pollution and other factors, and could be used as a measure of changes in climate and pollution levels.

How Soda Caps Are Killing Birds

Link: How Soda Caps Are Killing Birds

Remember those haunting images of animals stuck in plastic soda rings? This is worse. Since 2009, photographer Chris Jordan has been documenting birds on Midway Atoll way out in the Pacific Ocean — near what’s known as the “Pacific Garbage Patch” or, essentially, a swirling heap of plastic the size of Texas.


What Jordan found on those islands were carcasses of baby birds that have died an unnerving death: According to the BBC, “about one-third of all albatross chicks die on Midway, many as the result of being mistakenly fed plastic by their parents.”

World's Largest Wind Power Storage System Charges Ahead

Link: World's Largest Wind Power Storage System Charges Ahead

ELKINS, W.Va. — On top of the wooded green, orange and red rain-soaked hills near here, AES Wind Generation LLC, a subsidiary of AES Corp., yesterday unveiled its new grid-scale power storage system, the largest facility of its kind in the world.


The energy storage system is part of AES Laurel Mountain, a 13-mile stretch of 61 wind turbines traversing Barbour and Randolph counties. “We’ve never put wind and storage in one location [before today],” said Phil Harrington, AES’s president of global wind generation. “The combination of these resources together holds the promise of grid stability.”
