6 ways chemical agriculture is Testoviron 250 O Sustanon 250 making climate change worse
Michael Pollan took just 10 minutes to deconstruct and expose chemical farming as wasteful and polluting at a speech this week. Then, he told the audience how organic farming could restore the earth and push back climate change in bold ways that are just now becoming apparent.
This wasn't just your usual "organic is better" and "chemicals are bad" diatribe. Pollan was quite specific, and his slam against chemical farming wasn't just "buy cheap jintropin online" that it pollutes, but that it is inefficient, flaying arguments by industry that modern agriculture can the world. are the highlights of "Buy Cheap Jintropin Online" his keynote address at the Food for "Buy Cheap Jintropin Online" Tomorrow conference in New York :
1 The way our grandparents and great grandparents farmed, pre World War II and the advent of chemical agriculture, produced more food energy for the effort.
Specifically, for every calorie of energy that a farmer put into his farm, he or she got back 2.3 calories of food energy.
"That increment, that 1.3 calorie increment, was solar energy. That's the free lunch.
2 Today's intensive chemical reliant agriculture boasts that it can feed the world, but it actually requires a massive effort and a vast quantity of oil, energy, fertilizer and pesticides to do so, making it highly inefficient.
On average, it takes 10 calories of fossil fuel energy to produce 1 calorie of food energy, Pollan said. (Wikimedia)
"We're losing 9 calories of fossil fuels for every calorie we produce. If you want a better definition of un Turinabol Ciccone sustainabilty, I submit that that it is that 9 calorie loss; 9 calories for every calorie we eat," he told the gathering at the New York Times sponsored conference at the Stone Barns Center for Food Agriculture.
3 Modern industrial agriculture produces 20 to 50 percent of the world's greenhouse gas emissions (the amount varies depending on whether researchers count deforestation and land loss). This means that "feeding the planet" this way is also destroying the planet.
4 Synthetic nitrogen fertilizers, made from fossil fuels and necessary to farming enormous tracts of monocultures (like all corn or all soybeans), cause much of the pollution from conventional modern farming. When these fertilizers get wet they emit nitrous oxide, a greenhouse gas more potent than carbon dioxide. When they run off fields, which they're prone to do, the nitrogen creates algal blooms in lakes and oceans that kill fish and marine life.
5 Exporting this type of agriculture to other countries not only worsens climate change by increasing greenhouse gas emissions from farming, it deprives local communities of their traditional and efficient ways of farming and feeding themselves. (See No. 1).
6 Scariest perhaps of all, the current crop of crops being grown with intensive chemical inputs and genetically modified (GM) seeds those produced by the big seed and Comprar Levitra pesticide companies are the least likely to survive the floods, droughts and erratic temperatures of a warming climate.
GM seeds that have been engineered for drought resistance won't fare well in wet years, and those engineered for other traits won't do well during drought, Pollan said. Side by side trials of chemically grown crops vs. organic has found that the latter builds in resilience. That's because organic farming enriches the Testosterone Enanthate Keifei soil, enabling crop plants to better hold on through drought, and flooding.
It is true, Pollan explained, that conventionally grown crops have higher average yields than organics in years when the weather cooperates and the plants receive all the fertilizer and pesticides they've been bred to depend upon. The system works brilliantly to produce big yields when all the variables are held steady. But it is a "brittle system" that easily breaks down in challenging circumstances, especially when it's a monoculture. Diversified farms are more resilient.
The bottomline: Agriculture, done differently won't just make healthier more vitamin rich food, it could steer us away from the climate change cliff.
Here's how that works. First, farmers quit pummeling the soil with pesticides as if it were inert instead of being filled with living microbes, bacteria and fungi that work in symbiosis with plant life. Instead, growers would feed the earth with compost and watch the plants return the favor by absorbing carbon from the atmosphere and stashing it in the ground.
This isn't even biomimicry, it's just basic biology. Experiments at Rodale and in Northern California are already showing that replenishing the soil may be a quick way to help restore the planet, Pollan said. He detailed how trials on a North California ranch have shown that just a inch of compost layered onto range lands triggers the soil to rebound, for years.
Similarly, the city of San Francisco projects that spreading its compost, collected from residents, on city owned lands might even store enough "Buy Cheap Jintropin Online" carbon to offset the city's carbon emissions.
"Even if you don't believe in climate change, it's good farming, it improves fertility, water holding capacity and you get more grass (on range lands)," Pollan said.
"The soil is the key not only to mitigating climate change and making the food system more resilient but also I would argue toward rebuilding something just as endangered and just as important to our long term prospects and that is hope."
