Rice and wheat take a lot of water to grow and no one eats more than China. That also means no one contributes more to global warming from irrigation than China - a whopping 30 million tons of CO2 per year just from the pumping systems China uses.
Like everywhere, water usage has gone up in China with the surge in population. Groundwater used for crop irrigation in China has grown from 10 billion cubic meters in 1950 to more than 100 billion today. The pumping systems which support this immense irrigation network annually produce 33.1 MtCO2e (33.1 mega tonnes of carbon dioxide equivalent), claims a new study.
The old saying goes, a picture is worth a thousand words. In this case, a picture is worth millions. Millions of tons of carbon dioxide that could be saved if we stopped throwing food into landfills, that is.
Food waste is a pet peeve of mine. Yes, we do it at my house, probably way too much, but there is only so much nagging one can do. I don't have the yard space to do composting - yes, I know, smelly hippies will insist I do it anyway but it isn't always practical. However, there is a 100% chance is it better to put it in the garbage disposal than in the garbage, so I do that whenever practical (so, not bones).
Check out the graphic below. Some of it we can all easily do, some of it is not so easy.
Even one year after the disaster at the Daiichi nuclear plant in Fukushima, Japan, it is still unfolding. It was locally surpassing the severity of Chernobyl
relatively soon in the first few weeks. Four out of the six facilities were already no more than a pile of radioactive trash just like Chernobyl and it was clear since then that the future will be also similar to that of Chernobyl: A radioactive monument, still for our grand children’s grandchildren to be concerned about.
Scientists have reported the discovery of the floor of the world's oldest forest. They are now piecing together a view of this ancient site, dating back about 385 million years and - because virtually all studies have to reference global warming these days - they note their research could shed new light on the role of modern-day forests and their impact on climate change.
The recent discovery was made in the same area in Schoharie County, New York where fossils of the Earth's oldest trees, the Gilboa stumps, were discovered in the 1850s, 1920 and again in 2010 and were brought to the New York State Museum. The Museum has the world's largest and best collection of Gilboa fossil tree stumps.
These days it's common to hear about "ecosystem services," but what are they, really? According to G.C. Daily, who coined the phrase in 1997, ecosystem services are "the conditions and processes through which natural ecosystems, and the species that make them up, sustain and fulfill human life." Various authors have tweaked the definition over the years, sometimes to make it more accurate or specific to particular ecosystems. Recently, for instance, researchers amended the idea of ecosystem services to be more applicable to forests; their proposed definition referred to the "components of forests that are enjoyed, consumed, or used to produce specific measurable human benefits."
Writing in the most recent issue of Frontiers in Ecology and the Environment, an international team of collaborators has described nitrogen (N) as "the largest pollution problem in coastal marine waters." Excessive amounts of N sometimes fuel blooms of algae that can outcompete or even poison other organisms, and evaporation of N into the atmosphere in the form of nitrous oxide can cause damage to our delicate ozone layer. Most of the nitrogen along our coasts is deposited there by rivers that pick up N-rich sewage, fertilizer runoff, and atmospheric deposits caused by the burning of fossil fuels; in other words, nitrogen is yet another form of anthropogenic pollution.
One of the most effective arguments for science solutions to agriculture issues is the misuse of pesticides. It's one area where activists and scientists agree.
Brown planthoppers are one of a rice farmer's worst fears. Considered a major scourge in rice-producing countries, planthoppers cause considerable damage by sucking sap from rice plants, causing them to wilt and die. They also transmit three viral diseases that stunt rice plants and prevent grain formation. The obvious solution of the past few decades has been to rely on pesticides but beneficial insects that prey on planthoppers are killed inadvertently when insecticides are misused or are used indiscriminately.
The last 65 million years of natural history in North America may be broken into six distinct, consecutive waves of mammal species diversity, or evolutionary faunas', according to a new paper in the Proceedings of the National Academy of Sciences.

Trillions Of Fat-Busting Bugs To Be Deployed To Help Fight Sewer Fat
Trillions of fat busting bugs are being deployed from today (Thursday 22 December) by Yorkshire Water over the festive period as it bids to rid its sewers of fat blockages and prevent pollution.
Green solutions have made lofty claims in the last few decades but they have been optimistic hope more than reality. Simulations from the University at Buffalo may change that; they say it's possible for drivers to cut their tailpipe emissions without significantly slowing travel time.
In computer models of traffic in Upstate New York's Buffalo Niagara region, they found that green routing could reduce overall emissions of carbon monoxide by 27 percent for area drivers, though they did it by increasing the length of trips an average of 11 percent.
