Main contributors to Ozone Layer depletion.
1. Heavy industry / Power stations
2. Car / vehicle pollution
3. Livestock (cattle and sheep) belching methane into the atmosphere
FEED THE WORLD:
Land use: We are able to produce 6 to 7 times more food and feed more of the world’s population by utilising land for crops instead of running livestock. Sheep, cattle and goats in particularly, eat grasses close to the growth stem, thus inhibiting re-growth retarding the re-oxygenation of the atmosphere.
NATURAL CYCLE OF LIFE: ( a compatible reciprocating cycle)
Plants absorb Carbon dioxide and PRODUCE and respire Oxygen.
Whereas animals require Oxygen and respire Carbon Dioxide.
GARLIC EASES COWS GASSY OUTPUT
Pungent garlic could be a breath of fresh air for the environment with new research showing cows fed with garlic produce half as much greenhouse gas through methane emissions. A three-year study into the effectiveness of plant compounds in reducing methane gas emissions in livestock, has begun at the Institute of Rural Sciences at the University of Wales in Aberystwyth, The Press newspaper reported. Team leader Jamie Newbold said initial results showed garlic extracts could cut the methane produced by animals by up to half. The manager of New Zealand's Pastoral Greenhouse Gas Research Consortium, Mark Aspin, said the news was getting attention. "If it reduces methane by 50 per cent, then that is quite an astounding result," he told The Press. Livestock accounts for 55 per cent of New Zealand's total greenhouse gas emissions. The Welsh research team was also testing whether garlic tainted the milk or the meat from dairy cows and cattle.
Vast areas of snow in Antarctica melted in 2005 through to 2008 when temperatures warmed up for a week in the summer in a process that may accelerate invisible melting deep beneath the surface, NASA said on Tuesday. A new analysis of satellite data showed that an area the size of California melted and then re-froze -- the most significant thawing in 30 years, the U.S. space agency said. Unlike the Arctic, Antarctica has shown little to no warming in the recent past with the exception of the Antarctic Peninsula, where ice sheets have been breaking apart. Son Nghiem of NASA's Jet Propulsion Laboratory in Pasadena, California, and Konrad Steffen of the University of Colorado in Boulder measured snowfall accumulation and melt in Antarctica from July 1999 through July 2005. They found evidence of melting in several areas, including high elevations and far inland in January of 2005, when temperatures got as high as 41 degrees Fahrenheit (5 degrees Celsius).
"Increases in snowmelt, such as this in 2005, definitely could have an impact on larger scale melting of Antarctica's ice sheets if they were severe or sustained over time," Steffen said in a statement. "Water from melted snow can penetrate into ice sheets through cracks and narrow, tubular glacial shafts called Moulin," Steffen added. "If sufficient melt water is available, it may reach the bottom of the ice sheet. This water can lubricate the underside of the ice sheet at the bedrock, causing the ice mass to move toward the ocean faster, increasing sea level.“
