[New York Times]Sept. 21, 2019 Is the New Meat Any Better Than the Old Meat? https://www.nytimes.com/2019/09/21/climate/plant-based-meat.html The Impossible Whopper sold at Burger King — with the tagline “100% Whopper, 0% beef” — looks just like a juicy beef burger.
How does eating meat affect the environment? According to the Food and Agriculture Organization of the United Nations, livestock accounts for 14.5 percent of annual worldwide greenhouse gas emissions produced by human activity. Cattle (raised for beef and milk) alone produce 65 percent of livestock emissions. This happens because carbon dioxide, which contributes to global warming, is released into the atmosphere when forests are cleared to make room for animal feed production and livestock grazing. Animals also release methane, another powerful greenhouse gas, through burps and flatulence when digesting their food. Animal manure and rice paddies are also huge sources of methane.
Agriculture’s contribution to greenhouse gases varies by country, depending on how animals are bred, herded and fed, but some experts say the overall number is much higher than 14.5 percent. Jeff Anhang, environmental and social specialist with the World Bank Group’s International Finance Corporation, estimates that livestock production accounts for at least half of human-caused greenhouse gases.
The transportation and processing of plant-based products like the Impossible Whooper do have an environmental impact, but it’s insignificant compared with the transportation and processing of meat, Mr. Poore said. “No other change in your lifestyle can have such a dramatically positive and crosscutting benefit.”
Why are we hearing so much about plant-based meat now? “It’s clear the American palate has been trained on a diet of animal foods,” said Michele Simon, executive director of the Plant Based Foods Association, a trade organization. “For the average person, it will be difficult to trade hamburgers for salad, and this next generation of companies is trying to reach the hard-core meat eaters.” Paul Shapiro, chief executive of the Better Meat Company, which makes plant-based ingredients for companies to add to their poultry or meat, said it was the success of soy milk that pushed the plant-based meat movement into the mainstream. 0316名無しさん@1周年2019/09/23(月) 09:55:53.88ID:+PD1SQCk0 ニュースをにぎわしているのは肉だろ

A number of companies are active in making plant-based products. Ms. Simon said her trade association, which started in 2016 with 22 members, now has 157. But the two major disrupters are Beyond Meat and Impossible Foods. Impossible Foods is privately held, but Beyond Meat went public in May with the best-performing public option in recent history. 0317名無しさん@1周年2019/09/23(月) 09:56:22.31ID:+PD1SQCk0 肉の問題がずっとニュースだと思うんだけど。 ニュース見てないわけ?www

Scientists are cautious https://www.cnbc.com/2019/09/02/beyond-meat-uses-climate-change-to-market-fake-meat-substitutes-scientists-are-cautious.html As concerns mount over the dangers of a rapidly warming planet, upstart food companies are targeting a major climate-damaging food: beef. Beyond Meat and its privately held rival Impossible Foods have recently grabbed headlines and fast-food deals for their plant-based burgers that imitate the taste of beef. They’ve also turned the environmental benefits of abstaining from meat into a key marketing tool for their products — drawing some skepticism from environmental researchers who say plant diets are healthier and less carbon emitting than producing processed plant-based products.
As concerns mount over the dangers of a rapidly warming planet, upstart food companies are targeting a major climate-damaging food: beef. Beyond Meat and its privately held rival Impossible Foods have recently grabbed headlines and fast-food deals for their plant-based burgers that imitate the taste of beef.
Animal agriculture is responsible for 14.5% of global greenhouse emissions, according to the United Nations’ Food and Agriculture Organization, with 65% of those emissions coming from beef and dairy cattle. Scientists warn that climate change will trigger an international food crisis unless humans change the way they produce meat and use land.
Beyond and Impossible use different sources of proteins to create their meatless meats. Beyond primarily works with protein from peas, while Impossible uses genetically modified soy. “It makes sense to develop alternatives to beef, because we have to change our eating habits to more plant-based diets if we want to limit global warming to under 2 degrees Celsius. Impossible and Beyond tap into this market,” said Marco Springmann, a senior environmental researcher at the University of Oxford. “However, while their processed products have about half the carbon footprint that chicken does, they also have 5 times more of a footprint than a bean patty,” he said. “So Beyond and Impossible go somewhere towards reducing your carbon footprint, but saying it’s the most climate friendly thing to do — that’s a false promise.”
In fact, a recent landmark report from the Intergovernmental Panel on Climate Change, a group of UN scientists, said that shifting towards plant-based diets would be a critical way to mitigate and adapt to climate change, as simply cutting carbon emissions from automobiles and factories won’t be enough to avert an impending crisis. 0318名無しさん@1周年2019/09/23(月) 09:56:39.95ID:+PD1SQCk0 若年層の考えも理解していないみたいだw w w

Mintel found that 16% of U.S. consumers avoid animal products for environmental reasons. That reasoning is much more common with the 18 to 34 year olds, with nearly a quarter of that demographic saying that rationale applied to them. Still, if everyone in the U.S. were to reduce meat consumption by a quarter, and eat substitutes like plant proteins, it would save 82 million metric tons of greenhouse emissions each year, according to a new study in the journal Scientific Reports. If everyone went vegetarian, it would save 330 metric tons per year – roughly 5% saved. 0319名無しさん@1周年2019/09/23(月) 09:57:36.51ID:+PD1SQCk0 はい、また日本のマスコミの大ウソ。 [AFPBB]2009年2月16日 18:23 発信地:シカゴ/米国 [ 北米 米国 ] 「温暖化ガス排出食」の王者は牛肉、畜産分野の約80% https://www.afpbb.com/articles/-/2572329 食べ物と温暖化について語るのであれば、ハンバーガーは温室効果ガス排出の「最強打者」だと、カナダの科学者チームが警告した。 カナダ・ダルハウジー大学(Dalhousie University)の研究によると、メニューをビーフステーキからサラダに変えるだけで、 車を数日間使わなかった場合と同程度の二酸化炭素(CO2)排出を抑制できるという。 ■圧倒的に排出ガスの多い牛肉生産 これは、牛肉は生産過程が非常に非効率であると同時に、ウシ自身が呼吸や排泄物などで温室効果の高いメタンガスを多く排出するからだと言う。 ダルハウジー大のネーサン・ペルティエ(Nathan Pelletier)氏が15日、米イリノイ(Illinois)州シカゴ(Chicago)で開かれた 米国科学振興協会(American Association for the Advancement of Science、AAAS)のシンポジウムで報告した。 全世界の温室効果ガス排出の18%が畜産業関連と言われ、中でも牛肉生産による排出量が最も多い。 ペルティエ氏によると、先進国の食肉消費のうち牛肉が占める割合は30%に過ぎないが、畜産業全体の排出ガスの78%は牛肉生産に起因している。 ウシが食用処理されるまでに食べる穀物の量や、ウシのたい肥から発するガスなどを見ていけば、牛肉にかかっている本当のコストが明確に分かる。 例えば牛肉1キロの生産過程で排出されるCO2は重さ16キロ相当で、同じ1キロの豚肉生産の4倍、鶏肉に比べれば10倍以上だという。 ペルティエ氏は、牛肉から鶏肉に変えるだけでも、排出ガス量は70%削減できると指摘した。 ■「輸送時の排出を気にして地元産」は効果少 ペルティエ氏の発表を受けて会合後のインタビューで、カーネギーメロン大学(Carnegie Mellon University)のクリス・ウェーバー(Chris Weber)教授(土木環境工学)は、 「赤肉を食べるのを止め、乳製品を止めれば、1リットル約10キロ相当の燃費の車で約1万3000キロを走行した時に排出されるのと、ほぼ同量の排出ガスを抑制できる効果がある」と語った。 一方、輸送過程で生まれる排出ガスを抑えようという考えで、地元産の肉類や乳製品に切り替えてもそれほどの効果はないと言う。 輸送過程での排出量は牛肉生産全体の排出量の5%しか占めていないからだ。「週に1回、肉と乳製品をまったく食べない日を作るほうが、 1年中毎日地元のものに限った肉や乳製品を食べるよりもずっと大きな効果がある」 0320名無しさん@1周年2019/09/23(月) 09:57:55.15ID:+PD1SQCk0 はい、また日本のマスコミの大ウソ。 [WIRED NEWS (ITALIAN)]2012.12.11 TUE 15:25 肉食は自動車よりも二酸化炭素を排出する:研究結果 https://wired.jp/2012/12/11/meat_co2/ 週に一度しか肉を食べないことで、死亡率を下げて、自動車の走行距離750億kmに相当する二酸化炭素の排出量を削減することができる。 という研究が、世界自然保護基金によってドイツで行われた。 「もしわたしたちが肉を食べる量を少なくすれば、温暖化ガスの排出は、自動車の走行距離750億kmに相当する量を削減できるだろう」。 世界自然保護基金(WWF:World Wildlife Fund)によってドイツで行われた新しい研究でこう述べられている。 「もしわたしたちが肉やソーセージ、ハンバーガーなどの消費を週に1度だけに減らすことができるなら、大気への二酸化炭素排出量を900万t削減できます。 同じ結果を得るためには、個人使用での自動車の走行を750億km減らすといった具合に、かなりの規模で自動車の利用を制限しなければなりません」と、 WWFの気候食物部門の責任者、ターニャ・ドレーガー・デ・テランは語った。 0321名無しさん@1周年2019/09/23(月) 09:58:08.74ID:TTK1w74i0 レジ袋全部無くしても焼け石に水だろ すべての包装紙を廃止してむき出しで売るとかしないと 0322名無しさん@1周年2019/09/23(月) 09:58:09.40ID:+PD1SQCk0 [WIRED(UK)]2019.01.09 WED 18:30
