1
Chances are you or someone you know is a vegetarian, so we thought we'd try a thought experiment.
2
What would happen if everyone in the world was suddenly a vegetarian?
3
What effect would it have on our lives and the planet?
4
Before we begin, full disclosure: none of us at ASAP Science are vegetarians, and the worldwide rate of vegetarianism is fairly low,
5
ranging from about 4 -5 % in the US and Canada to a little over 30 % in India.
6
5 billion cows, over a billion sheep and nearly a billion pigs in the world.
7
Without any meat -eating humans to provide a market, whole herds of domestic animals would disappear.
8
And this would free up vast quantities of land.
9
About 33 million square kilometers of land are used for pasture, an area about the size of Africa.
10
And that's not even counting the land used to grow crops exclusively for animal feed.
11
Some of it would be needed for the increased amount of vegetable crops, but much of the land currently used as pasture is actually too dry to grow crops.
12
Without humans adding artificial nutrients, this land could turn to desert.
13
But if properly managed, it's possible that some farmland would return to its natural state of grassland or forest, which could help counteract global climate change.
14
After all, the loss of CO2 -absorbing trees cleared for agriculture is a major reason why global levels of CO2 are going up.
15
Cows and other grazers also affect our climate power than CO2.
16
combined with the loss of forests and other effects Livestock production is responsible for about 15 % of global greenhouse gas emissions,
17
which is more than all the world's planes, trains and automobiles put together.
18
In fact, many scientists believe that reducing meat consumption may be one of the best strategies for managing climate change.
19
A vegetarian diet would also greatly reduce water consumption.
20
Around 70 % of global freshwater consumption is used in agriculture.
21
It takes 15 ,000 liters to make a kilogram of beef 6 ,000 liters for pork, and 4 ,000 liters for chicken.
22
Compare this with 1 ,600 liters for cereal crops 900 liters for fruit and 300 liters for garden vegetables.
23
Of course, A kilogram of meat packs many more calories than the equivalent weight of fruit, but even if you compare the ratio of water per calorie of available food energy,
24
beef is still 5 times more water intensive than fruit, 7 times more than veggies, and 20 times more than cereal.
25
So are there any downsides to a vegetarian diet?
26
Well, we'd be left without a cheap source for many byproducts of livestock,
27
like leather from animal hides or animal fats which alternatives do exist,
28
their production would need to increase, meaning more land dedicated to growing crops and less restored to its natural state.
29
A more complicated fact is that raising and processing animals is a full time job for more than 1 billion people,
30
most of whom are small scale farmers in the developing world.
31
While some may be able to move to producing milk or eggs, or even growing vegetable crops, many would be faced with their way of life becoming obsolete.
32
Of course, any increase in vegetarianism is likely to be a gradual process rather than a sudden cutoff, and surprisingly, the trends are actually in the opposite direction.
33
In places like India and China, people are becoming wealthier and as a result consuming more meat which effectively cancels out the declines we see in other countries.
34
So we actually tried to go vegetarian for 21 days straight as an experiment in our new ASAP Thought episode.
35
Check out the video if you want to see how it went, what we learned in the process and how he felt about it both mentally and physically.

このレッスンについて
このレッスンでは、全世界が突然ベジタリアンになることについての思考実験を通じて、英会話の練習を行います。このトピックは、環境問題や食生活の変更が私たちの生活に与える影響について考える機会を提供します。特に、食生活の変化が環境や水資源に及ぼす影響についての語彙とフレーズに焦点を当てます。音楽や映像の助けを借りて、シャドースピーチやシャドースピークの技術を活用して、リスニングやスピーキングのスキルを向上させましょう。
重要な語彙とフレーズ
- ベジタリアン - 動物性食品を摂取しない人
- 環境への影響 - 食生活が生態系や気候に与える作用
- 温室効果ガス - 地球温暖化を引き起こすガス
- 農業用水消費 - 農業に必要な水の使用量
- 家畜の生産 - 肉や乳製品を得るための動物の飼育
- 食料エネルギー - 食品から得られるカロリー
- 持続可能な農業 - 環境に優しい方法で農作物を生産すること
- 反応する社会的傾向 - 食生活の変更に対する人々の行動の変化
練習のコツ
このビデオのペースやトーンに合わせてシャドーイングの技術を使用することで、効果的にスピーキング力を向上させることができます。以下のポイントを考慮してみてください：
- ビデオを見ながら、話者の発音やリズムに合わせて声に出してみてください。特に、重要な語彙やフレーズを強調して繰り返すことが鍵です。
- ビデオのスピードが速い場合は、一時停止してゆっくりと繰り返すことが有効です。これにより、表現の自然さを保ちながらスピーキング力を鍛えることができます。
- 他の学習者と一緒に練習するとお互いにフィードバックを出し合えます。シャドースピーチを通じて、協力して言語スキルを改善しましょう。
- 英語を母国語とする友人やオンラインのパートナーと一緒に練習するのも良い方法です。彼らの発音を真似ることは、シャドースピークの技術を磨く助けになります。
シャドーイングとは？英語上達に効果的な理由
シャドーイング（Shadowing）は、もともとプロの通訳者養成プログラムで開発された言語学習法で、多言語習得者として知られるDr. Alexander Arguelles によって広く普及されました。方法はシンプルですが非常に効果的：ネイティブスピーカーの英語を聞きながら、1〜2秒の遅延で声に出してすぐに繰り返す——まるで「影（shadow）」のように話者を追いかけます。文法ドリルや受動的なリスニングと異なり、シャドーイングは脳と口の筋肉が同時にリアルタイムで英語を処理・再現することを強制します。研究により、発音精度、抑揚、リズム、連音、リスニング力、そして会話の流暢さが大幅に向上することが確認されています。IELTSスピーキング対策や自然な英語コミュニケーションを目指す方に特におすすめです。
