Avoiding meat and dairy products is the single biggest way to reduce your environmental impact on the planet, according Consumismo e meio ambiente yahoo dating the scientists behind the most comprehensive analysis to date of the damage farming does to the planet.
Loss of wild areas to agriculture is the leading cause of the current mass extinction of wildlife. The scientists also found that even the very lowest impact meat Consumismo e meio ambiente yahoo dating dairy products still cause much more environmental harm than the least sustainable vegetable and cereal growing.
It assessed the full impact of these foods, from farm to fork, on land use, climate change emissions, freshwater use and water pollution eutrophication and air pollution acidification. Avoiding consumption of animal products delivers far better environmental benefits than trying to purchase sustainable meat and dairy. The analysis also revealed a huge variability between different ways of producing the same food. For example, beef cattle raised on deforested land result in 12 times more greenhouse gases and use 50 times more land than those grazing rich natural pasture.
But the comparison of beef with plant protein such as peas is stark, with even the lowest impact beef responsible for six times more greenhouse gases and 36 times more land. The large variability in environmental impact from different farms does present an opportunity for reducing the harm, Poore said, without needing the global population to become vegan. If the most harmful half of meat and dairy production was replaced by plant-based this still delivers about two-thirds of the benefits of getting rid of all meat and dairy production.
Cutting the environmental impact of farming is Consumismo e meio ambiente yahoo dating easy, Poore warned: It is Consumismo e meio ambiente yahoo dating [environmental] challenge like no other sector of the economy. Labels that reveal the impact of products would be a good start, so consumers could choose the least damaging options, he said, but subsidies for sustainable and healthy foods and taxes on meat and dairy will probably also be necessary.
The research also found grass-fed beef, thought to be relatively low impact, was still responsible for much higher impacts than plant-based food. The new research has received strong praise from other food experts. It is really important, sound, ambitious, revealing and beautifully done. But the new work has very many important details that are profoundly revealing. It brings together a huge amount of data and that makes its conclusions much more robust.
The way we produce food, consume and waste food is unsustainable from a planetary perspective. Given the global obesity crisis, changing diets — eating less livestock produce and more vegetables and fruit — has the potential to make both us and the planet healthier. My personal opinion is we should interpret these results not as the need to become vegan overnight, but rather to moderate our [meat] consumption. But I have stopped consuming animal products over the last four years

These impacts are not necessary to sustain our current way of life. The question is how much can we reduce them and the answer is a lot.
