Reuse and Recycle > Using flyash
Posted by Susan Sharma on February 01, 2008

Using flyash

Fly ash is a by-product of coal combustion in thermal plants. Presently majority of the coal ash generated is being handled in wet form and disposed off in ash ponds which is harmful for the environment and moreover ash remains unutilized for gainful applications. India has sufficient coal reserves. In India almost 65-70% of electricity production isdependent on coal which produces a huge quantity of Fly Ash as residue which is allegedly a waste product in Thermal Power Stations.

Fly Ash has a vast potential for use in High Volume fly ash concrete especially due to its physic-chemical properties.  Using fly ash in construction activity is environment friendly, reduce energy demand and restrict carbon emissions.  
Transco Delhi and DMRC have been using flyash in construction activities.

When mixed with lime and water the flyash forms a cementitious compound with properties very similar to that ofPortland cement. Because of this similarity, fly ash can be used to replace aportion of cement in the concrete, providing some distinct quality advantages.The concrete is denser resulting in a tighter, smoother surface with lessbleeding.

A good amount of research has already been done inIndia and abroad on its strength and other requisite parameters.

Wildlife > Endangered Giraffe
Posted by Susan Sharma on January 27, 2008

A Wildlife Conservation Society (WCS) study revealed that man and nature are threatening at least six distinct species of the African Giraffe, which are highly endangered and could face extinction if not protected. 


The extinction threat was real since giraffes are listed as lower risk in the World Conservation Union (IUCN) Red List, "under the assumption that giraffe species are considered a single species and therefore managed as such". 

"Severe poaching and armed conflict in Somalia, Ethiopia and Kenya reduced the number of reticulated giraffes   from about 27,000 individuals in the 1990s to currently fewer than 3,000 individuals over the past decade."

Environment Awareness > Cigarette butts
Posted by Susan Sharma on January 23, 2008

Cigarette butts, snack wrappers and take-out food and beverage containers are the most commonly littered items. Cigarettes are one of the most insidious forms of litter: Each discarded butt takes 12 years to break down, all the while leaching toxic elements such as cadmium, lead and arsenic into soil and waterways.

Interlinking of Rivers > Dams Coming Down in U.S!

Dams Coming Down

 

Two years of closed-door negotiations between farmers, Indian tribes, fishermen, conservation groups and government agencies have resulted in an unprecedented (but very conditional) agreement to remove four hydroelectric dams now operating along an embattled 300-mile stretch of the Klamath River in southern Oregon and northern California. The goal of the dam removal is to restore runs of the now-endangered salmon that were once plentiful in the region and to re-assign contentious water usage rights throughout the region accordingly..............

 ...........................................

 

Though it was once the third-most productive salmon river on the West Coast, the Klamath has suffered over the last several decades as a result of misguided hatchery practices, overfishing, development and the loss of habitat to dams, mining and logging. For the dams to actually be removed, the federal government would have to approve the dam removal plan (and put up the estimated $400 million to cover costs). Then, if dam owner PacifiCorp (a major regional utility) is willing to go along with the plan, the dams could be removed as soon as 2015.

Climate change and Global Warmimg > Organic farming combats global warming!

Organic farming combats global warming

 

Data from The Rodale Institute’s® long-running comparison of organic and conventional cropping systems confirms that organic methods are far more effective at removing the greenhouse gas, carbon dioxide, from the atmosphere and fixing it as beneficial organic matter in the soil………..

 

The key lies in the handling of organic matter (OM): because soil organic matter is primarily carbon, increases in soil OM levels will be directly correlated with carbon sequestration. While conventional farming typically depletes soil OM, organic farming builds it through the use of composted animal manures and cover crops………

 

 

"Agriculture and forestry are a very potent sink--they will make the emissions problem easier to get a handle on,”

Organic farming for carbon capture is also compatible with other environmental and social goals such as reducing erosion, minimizing impact on native ecosystems, and improving farmer livelihoods.

Environment Awareness > Are plastics the villain again?
Posted by Susan Sharma on January 17, 2008

Thousands of chemicals have come on the market in the past 30 years, and some of them are showing up in people’s bodies in low levels. Scientists studying obesity are focusing on endocrine disrupters - which have already been linked to reproductive problems in animals and humans - because they have become so common in the environment and are known to affect fat cells.

But could something in the environment also be making Americans fat in epidemic numbers?Animal studies in recent years raise the possibility that prenatal exposure to minuscule amounts of common chemicals - found in everything from baby bottles to toys - could predispose a body to a life of weight gain. The chemicals, known as endocrine disrupters, mimic natural hormones that help regulate, for example, how many fat cells a body makes and how much fat to store in them.These findings have led some scientists to put forth a provocative argument: They say diet and too little exercise clearly are key reasons for the worldwide rise in obesity in the past 20 years, but they may not be the only ones. Food intake and exercise just haven’t changed that much in that period, they argue. And while genetics obviously play a role - just think of someone you know who can eat three Big Macs a day and never gain an ounce - these researchers say it would be impossible to see such widespread genetic change in just two decades, giving them more reason to suspect the environment.

Corporates and Environment > Who is responsible
Posted by Susan Sharma on January 17, 2008

"In early 2007, thousands of cats and dogs in North America fell ill with kidney ailments. Many of the pets had dined chez Menu Foods Inc., a company in Ontario, Canada, that manufactures pet foods for more than 100 brands, including Procter & Gamble, Iams, Colgate-Palmolive’s Science Diet, and Wal-Mart’s Ol’ Roy. By mid-April, investigators had traced the animals’ illnesses to melamine, an industrial chemical that tainted a few of Menu Foods’ raw ingredients. They then followed the thread to two suppliers in China, which had spiked the ingredients to cut costs and boost profits.

So where should the public point its finger? Procter & Gamble, Colgate-Palmolive, Wal-Mart, and the many other corporations that own the pet food brands? Menu Foods, which mixed the kibble? The Chinese manufacturers, which adulterated the ingredients? The U.S. Food and Drug Administration, which failed to detect anything amiss? The stores that didn’t remove the foods from the shelves, even after Menu Foods recalled them? "

Ezine > Prizes to win!
Posted by Susan Sharma on December 20, 2007

ERIC NEE: What are the differences between traditional grant giving and using prizes as a way to stimulate social change?

THOMAS VANDER ARK: Quite simply, it’s the difference between push and pull. Traditional philanthropy is a push mechanism. You pick an organization, you make an investment, you may provide advice and performance management, and you hope that they are successful and that the sector evolves as you had anticipated. Prize philanthropy is a pull mechanism where you set a goal, invite the world to compete, and hope to be surprised by the new money, the new minds, and the new methods brought to the competition.
