When Sulphur, Copper and organo metallic pesticides were replaced by systemic fungicides and pesticides it was a great breakthrough. Cash crops like cotton attract maximum use of pesticides.
In a popular TV show in India, advice was given not to use pesticides and go for organic farming. Most of the villagers in earlier times were engaged in organic farming alone as they had no access to pesticides or fertilizers due to remoteness, lack of knowledge or paucity of funds. No doubt the government of India has spread the knowledge about agriculture to villages and now its quite common that villagers use both. However, more so in the case of cash crops like cotton, sugarcane or vegetables.
The following, scary pictures are making it around the net at present:
And here separating the fresh water:
A cap and trade system for carbon dioxide has been a terrific flop; even proponents are leery that it is just another layer of bureaucracy and the only economic benefits have been of the economic voodoo kind, similar to a federal stimulus package that went primarily to state and municipal union employees were called 'jobs saved' in a brilliant bit of marketing.
Why would anyone want to export that fiasco to another environmental issue? It's academic. Sometimes academic is obviously a good thing; basic research, for example. And sometimes 'academic' connotes 'out of touch with reality', like people in the humanities who try and argue that communism really works, it's just that no one has really tried it.
A new paper by Natural Resources Defense Council says hydraulic fracturing (fracking) generates massive amounts of polluted wastewater in in the Marcellus Shale that threatens the health of drinking water supplies, rivers, streams, and groundwater - and that federal and state regulations have not kept pace with the dramatic growth of fracking and must be strengthened to reduce the risks of health issues throughout the Marcellus region.
Did an environmental issue disappear because activist groups got a check? It would seem so. The National Resources Defenses Council and Santa Monica Baykeeper sued the city of Malibu in 2008 for 'groundwater' pollution.
The settlement they reached? Malibu has to 'fix' 17 drains, easy enough to rationalize since water can pick up garbage as it falls due to that nature thing that happens - but then they also have to donate $750,000 to the two groups that filed the lawsuit. How is that helping the environment? It isn't, but it keeps those environmental corporations in business so they can hire more lawyers to raise more money.
I wrote some time back of bad quality water causing soil damage.
Hinduatan Times (02.05.2012 confirms the same with findings placed at highest level.
Ground water pockets in 158 out of 639 districts have gone saline. I may add at this point that as we go deeper in drilling in soil crusts we encounter exposed rocks which add salinity and heavy metals to ground water. Moreover, in Nagaur district of Rajasthan two wells dug at close distances of 100 m can show good or bad quality water.
In 267 districts, ground water contains excess of fluoride, in 385 nitrates. 53 districts show arsenic and 63 districts contain heavy metals such as lead , chromium and cadmium. East Delhi water contains chromium.
Every once in a while, I like to go for a run on the beach. One of my favorite spots to hit the sand is San Gregorio State Beach – it lies just across the Santa Cruz range, is invariably quiet early on weekday mornings, and offers a good stretch of hard-packed sand along a southern route toward Pomponio State Beach.
At least, when the tide is out.
Whether you are concerned about Mayans, a worldwide infrastructure collapse or an exploding supervolcano, science has some good news for your doomsday preparation - sunlight and a twist of lime are an inexpensive and effective way to quickly improve the quality of your drinking water.
Researchers have found that adding lime juice to water while using a solar disinfection method removed detectable levels of harmful bacteria such as Escherichia coli (E. coli) significantly faster than solar disinfection alone.
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.
