“All the models have been extensively peer-reviewed and have been widely used by our group and by many others,” says Hill.To determine the health impact of animal-related products, the study’s authors looked at what it takes to produce them—such as fertilizing crops, tilling land, burning diesel engine tractors, and managing the waste produced by livestock.
In contrast, vegetables, the category encompassing the corn that humans eat, contributes to 100 deaths, they found. Individuals can affect change, as well. If consumers adopted a national dietary shift it would have a big impact on air quality, the scientists say. If the U.S. changed dietary preferences from red meat to poultry, for instance, they estimated 6,300 deaths could be prevented. By going vegetarian, vegan, or flexitarian—eating meat sparingly—consumers could prevent anywhere from 10,700 deaths to 13,100 deaths as a result of air pollution, they estimate.
In agriculture, PM 2.5 can come directly from dust, tilling the land, or exhaust from diesel combustion engines used by tractors. It is also created from pollutants like the ammonia—found in fertilizer, manure, and—undergoing chemical changes in the atmosphere that turn the gaseous pollutant into particulates.
The Cattlemen’s Association challenged the modeling methods and EPA data. Ethan Lane, the group’s vice president for government affairs, said in a statement that the research “attempts to cultivate a misleading narrative that ammonia emissions from farms are responsible for thousands of deaths. No such federal methodologies for agriculture exist, which casts serious doubt on the accuracy of these conclusions.
“We know what the direct effect is of [PM 2.5] on the lung. That can cause diseases and chronic inflammation like asthma, but the cardiovascular part of this is a little bit different,” says Harkema.
All bullsxxt....
Unfortunately the leaders of our countries are driven by short term economics rather than science.🤡🤬
No one tell them how much energy is spent or damage is caused by growing quinoa or avocados
Eating less bovine during the Pandemic will help avoid the Covid, a diet rich in vitamin B complexes and spinach instead of lettuce also improves your ability to enhance your immune system to disease. Healthwise
80 percent of the crop that livestock eat is bi product , the waste from human plant foods that we can't eat . If livestock didn't recycle this into usable protein we would need to plough and fertilise even more land. Livestock grazed land also sequesters carbon more than forest
My how attitudes have changed. WWI 'come on Marine let's go, what do you want to do live forever.' Now we need a study to find out if driving through dust created by a farmer plowing in air conditioned SUV's shortens life.
Ya but its delicious so who cares.
