Reducing carbon, and health problems in the 3rd world

stacks_image_392_1

The Problem

In the late 1980’s, medical teams reported an alarming number of children being treated for burns and respiratory problems. A number of concerned volunteers found the problem emanated from the way people cooked.

Most of the poor continue to cook over indoor fires located on the floors of unventilated homes. These fires cause debilitating burns, skin and eye problems.

Excessive smoke in homes results in respiratory problems that, according to the World Health Organization, are the leading cause of death in children under the age of five. Testing of carbon monoxide, a deadly toxin, found readings in the homes to be as much as twice the level considered dangerous.

These inefficient open fires also result in massive deforestation.

The Solution

After an exhaustive investigation of the cultural and technological factors surrounding open fires, the new, fuel-efficient Ecocina stove was developed by StoveTeam International. It is economical to build and operate, saving up to 60% of the wood currently used while also reducing particulate matter and carbon output by 70%.

Greenpeace – Making Waves: Bluefin tuna action in Turkey

 

 

Activists on board the Rainbow Warrior hit the water today to demand immediate action to protect the endangered Mediterranean bluefin tuna from commercial extinction. They deployed buoys marked “Crime Scene” around cages holding bluefin tuna which are being fattened up for harvesting to then be sold for export — mostly as luxury gourmet Sushi.

The action comes just days after the European Commission announced its support for a ban on trading North Atlantic and Mediterranean bluefin tuna, under rules governing the trade of endangered species. That’s a great move, long overdue, but why, people, why do we continue to let the threat of extinction be the only really powerful regulator that the fishing industry has to face? What we really need, if we want fish for tomorrow, is Marine Reserves today.

Icecap photo shows ‘mother nature in tears’ – Telegraph

Marine photographer and environmental lecturer Michael Nolan captured the pictures while on an annual voyage to observe the largest icecap in Norway Austfonna on July 16.

He said the image looked just like mother nature in tears, “as if she was crying about our inability to reduce global warming”.

‘Tears’ in the natural sculpture were created by a waterfall of glacial water falling from one of the face’s ‘eyes’.

Mr Nolan has visited Norway’s largest the icecap on the island of Nordaustlandet in the Svalbard archipelago for several years.

“The icescape changes every year I visit. Every summer the route has less ice as the polar cap retreats,” he said.

“On this trip I was struck myself by the amazing image of a woman’s face, a motherly face, crying. Totally natural but very animated because of the amount of melt water running off.

“This is how one would imagine mother nature would express her sentiments about our inability to reduce global warming. It seemed an obvious place for her to appear, on the front of a retreating ice shelf, crying.

“It exactly fits with my image of mother nature, wise to the way of the world, and saddened by it.”

Jon Ove Hagen, a member of the World Glacier Monitoring Service (WGMS) and professor in geosciences at Oslo University, Norway, has been studying the Austfonna ice-shelf since 1988.

He said the Austfonna icecap has been shrinking by as much as 160 feet every year for several decades.

“The geometry of the ice cap is changing. The fronts are retreating, the lower parts are getting thinner, with a thinning rate of about three feet-per-year while the interior of the ice cap is thickening with about 1.6 feet-per-year,” he said.

“The ice cap is losing about 1.6 cubic miles of ice every year.”

” It is of course a concern, but not more than in other parts of the world were we see even more rapid changes than here.”

Fun Facts You Didn’t Know About Recycling

recycling-3

“Recycling means more material to collect.”

FACT: The same amount of waste is generated as with an all-disposal system. That waste is just separated into useful categories that can be reprocessed into usable goods.

“Not recycling is cheaper than recycling.”

FACT: Recycling should always be compared against disposal, since the material still must be transported off campus. Not recycling means paying for more disposal.

“Since we have plenty of landfills, recycling isn’t important.”

FACT: Recycling has many more benefits than reduced landfill use, the chief of which are the conservation of natural resources (trees, oil, minerals, etc.), reduced energy consumption, and the pollution and environmental impact associated with them (clear-cutting, oil drilling, mining, burning coal to melt steel, etc.). By recycling, you are conserving natural resources and reducing the amount of pollution and greenhouse gasses released into the environment. Also the impact of landfills is greater than simply the space they take up. As organic matter (anything that was once living) breaks down in a landfill, it produces methane, a potent greenhouse gas. By reducing the amount of organic material sent to the landfill, by composting, paper recycling, etc., you are helping to reduce greenhouse gasses.

“Recycling bins are ugly and cannot fit into the local aesthetic.”

FACT: Recycling bins, which are the same as trash bins, come in every shape, style, and color and can fit into nearly any aesthetic scheme.

“Facilities Management staff go through the trash and pull out the recyclables before they reach the landfill.”

Anything thrown into the trashcan will end up in the landfill. The labor required to sort through trash after it has already been mixed is prohibitive and so almost never happens. The only feasible way of separating recyclables is “source separation”, meaning each person separates their trash at the time they throw it away. The only effort here is the difference between throwing trash into one bin or another.

“Only white paper is recyclable.”

FACT: Just about any type of paper is technically recyclable, including envelopes, post-it notes, colored paper, newspaper, and magazines. Some universal restrictions are waxy or thermal paper (for older fax machines), laminated paper, and food-stained paper. However, different recycling companies require different mixes and restrictions. Make sure to check with your recycling program to find what is recyclable in your program.

“Incineration is safe these days and you can burn it for the electricity.”

FACT: Incineration still produces emission including air pollutants and greenhouse gasses. While it is true that some incinerators also produce electricity, it is not without impact. Recycling the material, or reusing or reducing its use, will save electricity and is a much more efficient way of handling the material.

“It’s OK to throw something away as long as it’s biodegradable.”

FACT: Biodegradable waste breaks down into methane in the landfill, if at all. It is usually released into the atmosphere, where it is a potent greenhouse gas. Some landfills are actually big, sealed storage bins, which make the decomposition of any biodegradable substance impossible once the landfill has been sealed up. A better solution is to recycle the material, or even better, reuse it or reduce its use altogether. Non-biodegradable waste does not produce methane, but it also will not break down in the landfill, thus using more space. Composting biodegradable material is an effective option.

Fun Facts:

  • One ton of paper made completely from recycled scrap saves 7000 gallons of water, 4100 kilowatt-hours of energy, three cubic yards of landfill space, and 17 trees
  • Each year, the United States uses 85.5 million tons of paper, of which we recycle only 22%, or 19 million tons. Of the remaining paper, we could recycle up to 70% or 46 million tons. And those 46 million tons could save 782 million trees.
  • Recycling 1 ton of glass saves the equivalent in energy of 10 gallons of oil.
  • Americans represent only 5% of the world’s population, but generate 30% of the world’s garbage.
  • We can really accomplish a lot when we all pull together and recycle! During WWII, salvaging metal straps from corsets saved enough metal to build 2 warships.
  • Every individual in the United States produces an average of 4.3 lbs. of garbage every day!
  • Producing a soda can from recycled aluminum uses 96% less energy than manufacturing a can from ore and produces 95% less air pollution and 97% less water pollution.
  • Over a ton of resources are saved for every ton of glass recycled:
    • -1,330 lbs. of sand
    • -433 lbs. of soda ash
    • -433 lbs. of limestone
    • -151 lbs. of feldspar
  • Every ton of paper recycled saves enough energy to heat and air condition the average American home for at least six months.
  • Americans use four million plastic bottles every hour, yet only one out of four is recycled.
  • 1 ton of aluminum saves the equivalent in energy of 2,350 gallons of gasoline. This is equivalent to the amount of electricity used by the typical home over a period of 10 years!
  • The average American uses 650 lbs. of paper a year.
  • One ton of paper from recycled pulp saves 17 trees, 3 cubic yards of landfill space, 7000 gallons of water, 4200 kWh (enough to heat your home fore half a year), 390 gallons of oil, and prevents 60 pounds of air pollution.
  • More than half of plastic containers still go straight into landfills or incinerators.
  • Glass never wears out — it can be recycled forever! Bad news: Americans throw away enough glass bottles and jars every two weeks to fill the 1,350-foot towers of the World Trade Center. Good news: Americans recycled enough glass last year to fill New Jersey’s Giants Stadium more than 3 ½ times.
  • In 1993, for the first time in history, more paper was recovered for recycling in the United States than was landfilled.
  • The energy saved from recycling aluminum in 1993 alone was enough to light a city the size of Pittsburgh for six years.
  • “Tin” cans (like those used for tuna and soup) are actually 99% steel. Americans throw away enough steel every year to build all the new cars made in America.

8-Story Antigravity Forest Facade Takes Root

By Cliff Kuang 08.24.09

When Patrick Blanc was a boy, he suspended plants from his bedroom wall and ran their roots into a fish tank. The greenery received nourishment from the diluted—ahem—fertilizer and purified the water in return. Forty-five years on, the French botanist’s gardens have grown massive in scale. One inside a Portuguese shopping mall is larger than four tennis courts, and there’s one in Kuwait that’s almost as big. But Blanc’s recently completed facade for the Athenaeum hotel in London (shown) could be his most high-profile project yet. Looming over Green Park, it’s an eight-story antigravity forest composed of 12,000 plants.

Blanc uses a kind of techno-trellis as the underlying structure: A plastic-coated aluminum frame is fastened to the wall and covered with synthetic felt into which plant roots can burrow. A custom irrigation system keeps the felt moist with a fertilizer solution modeled after the rainwater that trickles through forest canopies.

But plants for this vertical landscape must be chosen with care. Because the walls are so high, conditions vary widely. The shade at ground level is perfect for rare Asian nettles; on the brighter upper stories, plants that usually cling to windblown cliff faces brave the blustery British breezes.

Blanc, who still has a fish-tank setup in his apartment, says his creations will always reach upward: “I leave horizontal gardens to others. I only think vertically.”

The vertical garden at the Athenaeum, which is eight stories tall, has 260 plant species and more than 12,000 plants

Eighty percent of the plants at the Athenaeum are evergreen; 20 percent are seasonal. They are planted according to environmental demands — those that need more sun, for example, go up top. Ferns go below, where there’s more shade.

Blanc designed the first vertical garden in Spain, which covers an entire wall facing the entrance of the CaixaForum Madrid, designed by starchitects Herzog & de Mueron
