How to have a Green Christmas Each year, 50 million Christmas trees are purchased in the U.S. Of those, about 30 million go to the landfill. And added to this is the carbon cost in transporting all these trees to the landfill. Much of the environmental costs associated with the holidays can be reduced by simple awareness and some pre-planning. • Reuse or recycle gift packing materials Bubble wrap can be stored for reuse, or recycled. Foam packing chips are not as easily recycled; if you don't want to store this material for reuse, take it to a shipping center like Mailboxes. etc, who will accept it for their own use. Note: Never burn Christmas tree branches in your fireplace.
Has Earth Passed the Tipping Point? Worldwide, carbon dioxide (CO2) levels have risen again , according to the National Oceanic and Atmospheric Administration (NOAA). The rise, a disturbing 2.6 parts per million over 2006 levels, is attributed primarily to the burning of fossil fuels. However, another factor, which may present its own tipping point, is global warming’s effect on forests. When the earth warms, several things happen to forests. Boreal forests are displaced farther north, and the timberline (the altitude beyond which trees can’t grow) rises. Where warming is precipitous, forests fail to adapt and die, or are ravaged by pests which thrive in the absence of annual freezing. Forests act as carbon sinks, or storage depots. Forest destruction is now happening all over Canada , as pine beetles destroy more than 50,000 square miles of forest, releasing an estimated 270 megatons of CO2 over the next 14 years. The same infestations are being seen in the U.S. Further Reading:
Welcome, Robot Overlords. Please Don't Fire Us? Smart machines probably won't kill us all—but they'll definitely take our jobs, and sooner than you think. Illustrations by Roberto Parada This is a story about the future. Not the unhappy future, the one where climate change turns the planet into a cinder or we all die in a global nuclear war. This is the happy version. The result is paradise. Maybe you think I'm pulling your leg here. But they're not. What do we do over the next few decades as robots become steadily more capable and steadily begin taking away all our jobs? Suppose it's 1940 and Lake Michigan has (somehow) been emptied. By 1950, you have added around a gallon of water. At this point it's been 30 years, and even though 16,000 gallons is a fair amount of water, it's nothing compared to the size of Lake Michigan. So let's skip all the way ahead to 2000. But wait. IF YOU HAVE ANY KIND OF BACKGROUND in computers, you've already figured out that I didn't pick these numbers out of a hat. And that's exactly where we are.

German village generates 321 percent more renewable energy than it needs, earns millions selling it back to national power grid (NaturalNews) Developing a renewable energy system that creates energy independence and even a considerable new source of revenue is not some sort of sci-fi pipe dream. BioCycle reports that the German village of Wildpoldsried, population 2,600, has had such incredible success in building its renewable energy system. Wildpoldsried generates 321 percent more renewable energy than it uses, and it now sells the excess back to the national power grid for roughly $5.7 million in additional revenue every single year. By utilizing a unique combination of solar panels, "biogas" generators, natural wastewater treatment plants, and wind turbines, Wildpoldsried has effectively eliminated its need to be attached to a centralized power grid, and created a thriving renewable energy sector in the town that is self-sustaining and abundantly beneficial for the local economy, the environment, and the public.
Sci-Fi-Nano-Future-Blog By examining decades’ worth of stored bacteria samples, researchers have determined how a benign organism evolved into a deadly pathogen that causes necrotizing fasciitis, commonly known as flesh-eating bacteria disease. Using genetic sequences from more than 3,600 strains of bacteria, scientists were able to see that it took only four steps to create the unusual microbe that spreads rapidly and destroys the body’s soft tissue. Their report was published Monday in the Proceedings of the National Academy of Sciences. Necrotizing fasciitis is caused by several types of bacteria, most commonly group A Streptococcus. (See images of Streptococcus and other microbes in the “Small, Small World” photo gallery.) An international group of researchers sequenced the genomes of group A strep bacteria in samples that had been collected from as early as the 1920s. A Long Search for Answers Jacqueline Roemmele was one such unlucky person. The new discovery “is very exciting,” Roemmele said.

Who's to blame for supermarket rejection of 'ugly' fruit and vegetables? Huge amounts of perfectly edible, nutritious fresh produce is wasted for not meeting cosmetic standards. Professor Davey Jones of Bangor University has been conducting studies on farms in East Anglia and has been shocked by just how much food waste is still edible. 'I’ve walked through fields after harvest and 90 per cent of the wasted crop is still worthwhile. Much of this waste occurs due to produce not meeting the ‘technical specifications’. These ‘specs’, as they are referred to within the industry, stipulate the size, shape and skin finish of produce retailers will purchase and at what price. 'Unlike what most people seem to believe the eating quality of a potato is not indicated by skin finish but by variety and age,” says Tony Bambridge, managing director of B&A farming. Weather ruins perfect veg All crops pose unique challenges in terms of meeting the ‘specs’. 'And that’s fair enough,' says Chambers. Fields of wasted crops On a spreadsheet this appears an efficient margin.
World's first lab-grown burger is eaten in London 5 August 2013Last updated at 15:50 ET Food critics give their verdict on the burger's taste and texture The world's first lab-grown burger has been cooked and eaten at a news conference in London. Scientists took cells from a cow and, at an institute in the Netherlands, turned them into strips of muscle that they combined to make a patty. One food expert said it was "close to meat, but not that juicy" and another said it tasted like a real burger. Researchers say the technology could be a sustainable way of meeting what they say is a growing demand for meat. The burger was cooked by chef Richard McGeown, from Cornwall, and tasted by food critics Hanni Ruetzler and Josh Schonwald. Continue reading the main story Analysis Pallab GhoshScience correspondent, BBC News The world's population is continuing to increase and an ever greater proportion want to eat meat. And then of course there is the taste. "This is meat to me. Food writer Mr Schonwald said: "The mouthfeel is like meat.
UndergroundHouse : Underground House The Purpose of this Group is to bring together as much information as possible for the building of an Underground / Earth Sheltered (ES) House that will be Self Heating / Cooling, Off Grid & Food Self Sufficient. There are two main objections to ES houses, which is that they are Dark & Damp, I intend to overcome these by: 1. Building a Back Yard Patio, conceived by Mike Oehler, onto the rear of the house, allowing in natural light, with the advantage of deflecting water away & to the sides into the underground drains. & 2. Installing an Insulated Watershed Umbrella such as John Hait’s system of Passive Annual Heat Storage (PAHS). To be food Self Sufficient, an ‘underground’/ Earth Sheltered greenhouse (similar to Mike Oehler’s designs) can be built at the side of the house, here small scale aquaculture & hydroponics can be carried out. Electricity can be generated using Wind Turbines & Hot Water with Solar Panels, these can be made & maintained much cheaper than commercial alternatives.
The Future of Marine Fish Resources December 2009 Overfishing continues despite repeated warnings about the decline in the ocean’s population of Atlantic, or Northern, bluefin tuna ((Thunnus thynnus). Source: Osaka Aquarium, Japan; OpenCage.info. Fisheries have transformed the world’s oceans . Overfishing impacts resources. Status of global marine fisheries Currently, fishing pressure appears to be near—if not beyond—the ocean’s capacity to provide. Half the world’s stocks are at maximum sustainable limits. What about individual fish stocks? Entire ecosystems are affected by fisheries. Fishing impacts have fallen especially hard on slow-growing predators. Marine biodiversity and fishery production Fewer marine species have lower productivity. Declining catches are an indication of declining stocks. While such factors can obscure population trends for individual stocks, however, no compelling evidence has been suggested that globally averaged catch data significantly misrepresent trends in global fish abundances. 1. 2. 3.

Soybean Car World's first plastic car Plastic car frame patent 2,269,452 (February 13, 1942) Soybean car frame patent, Fig. 2 The Soybean car, more recently referred to as the Hemp body car, was a car build with agricultural plastic and was fueled with hemp combustible (oil or ethanol). Although the formula used to create the plasticized panels has been lost, it is conjectured that the first iteration of the body was made partially from soybeans and Hemp.[A] The body was lighter and therefore more fuel efficient than a normal metal body. It was made by Henry Ford's auto company in Dearborn, Michigan, and was introduced to public view on August 13, 1941. History Henry Ford first put Eugene Turenne Gregorie of his design department in charge of manufacturing. Because of World War II all US automobile production was curtailed considerably, and the plastic car experiment basically came to a halt. Reasoning for a plastic car Car ingredients Quotes
