The chickens came home to roost in Brazil.
The use of food to make ethanol damages our environment, is depleting the soil and diverts the resources from fighting hunger to pollute the planet. It is a sin. Brazil that was so proud to produce so much ethanol is starting to see the consequences of it’s reckless policies of deforestation and using the land for ethanol production.
“Sao Paulo, Brazil’s megacity of 23 million, could soon run out of water, experts warn, as the city continues to suffer its worst drought in 80 years and scientists say decades of deforestation of the Amazon rain-forest may be to blame.” http://latino.foxnews.com/latino/news/2014/12/04/sao-paulo-on-brink-running-out-water-and-amazon-rainforest-destruction-to-blame/
Still in denial.
Climate change is denied by the country’s new science minister, Aldo Rebelo, who has declared the environmental movement is “nothing less, in its geopolitical essence, than the bridgehead of imperialism”.
“Scientists think otherwise. As well as global warming, they say Brazil’s weather patterns have been disrupted by the loss of Amazon rainforest and the growth of cities.” http://www.theguardian.com/world/2015/jan/23/brazil-worst-drought-history?utm_content=buffer9d02a&utm_medium=social&utm_source=twitter.com&utm_campaign=buffer
Side effects of Ethanol.
There has been hot debate about whether carbon emissions from ethanol production and use are lower than those from oil and whether the 33 percent of the U.S. corn crop diverted to ethanol drives up the price of food. Local effects of ethanol production, however, including water pollution and consumption, have received less scrutiny.
Fertilizer and pesticide runoffs from the U.S. Corn Belt are key contributors to “dead zones” in the Gulf of Mexico and along the Atlantic Coast. A 2008 study by independent researchers, published in the academy’s Proceedings journal, calculated that increasing corn production to meet the 2007 renewable fuels target would add to nitrogen pollution in the Gulf of Mexico by 10 to 34 percent.
Destruction of rain forest
The cutting of trees, scientists say, is hindering the immense jungle’s ability to absorb carbon from the air — and to pull enough water through tree roots to supply gigantic “sky rivers” that move more moisture than the Amazon river itself. More than two-thirds of the rain in southeastern Brazil, home to 40 percent of its population, comes from these sky rivers, studies estimate. When they dry up, drought follows, scientists believe. http://latino.foxnews.com/latino/news/2014/12/04/sao-paulo-on-brink-running-out-water-and-amazon-rainforest-destruction-to-blame/
More harm than good.
David Pimentel of Cornell University, in Ithaca, NY, whose own studies have shown that ethanol requires more energy to produce than it releases when burned, and that the fertilizer used to grow corn for ethanol has contributed significantly to dead zones in the Gulf of Mexico (areas of the ocean with low oxygen content due to increases in chemicals in the water). http://www.technologyreview.com/news/413002/measuring-corn-ethanols-thirst-for-water/
So what is the car fuel of the future?
