There are currently 7.5 billion people alive on Earth,

現在地球上有 75 億人口，

of which 323 million live in the United States of America

其中有 3.23 億人生活在美國，

As a global powerhouse, many have an opinion on the American Lifestyle.

作為世界強國，許多人選擇過著美式生活。

But what do the statistics say,

但統計資料表示，

and what would actually happen if we all lived like Americans?

如果我們都像美國人一樣生活會發生什麼事？

First off you would be having more sex.

首先，你會有更多的性生活

Surveys indicate that Americans have sex 138 times per year on average

調查指出美國人平均一年會有 138 次性行為，

which is the second highest in the world behind France.

世界排名第二僅次於法國。

Porn would also be even more abundant as 73 percent of the world's porn is produced in America.

色情影片更是數不完，全世界 73% 的色情影片都是美國所生產。

Americans drive thirteen thousand four hundred and seventy-six (13,476) miles per year,

美國人每年開 13,476 英里的路，

which is the most in the world.

這是世界最多的。

This explains why they have the highest rates of vehicle collisions worldwide

這也說明為什麼世界車禍發生最多的是美國，

and number of meals eaten in a car.

還有在車上吃最多食物的。

Seriously. Statistics show that twenty percent of American meals are consumed in a vehicle.

認真說來，統計指出有 20 % 的美國食物是在車上吃的。

Americans eat eight ounces of meat per day on average

美國人平均一天吃下 8 盎司的肉，

which is almost double the world average.

這是世界平均的兩倍。

This leads to Americans killing and eating 10 billion animals annually,

這也導致美國每年會宰殺和吃下 100 億頭動物，

which is 15 percent of the world's total consumption.

是全世界總食用量的 15 %。

The average American also drinks 403 Coca Cola products per year

美國人平均一年也會喝下 403 罐的可口可樂，

compared to the world's average which is 92.

相比之下世界平均是 92 罐。

This all contributes to the U.S. having the highest total caloric intake, sugar intake, and fat intake compared to all of the other 16 wealthiest countries.

比起其他 16 個最富裕的國家，這讓美國在卡路里、糖、脂肪的攝取量上也是最高，

But consumption is similar in one category: fruit and vegetable consumption.

但是有一類攝取量是相似的：蔬果攝取量。

And all of this eating contributes to trash.

這些食物也導致出垃圾問題。

Americans throw out 1.6 billion pens and 220 million car tires per year.

美國人每年丟棄 16 億枝筆和 2.2 億個汽車輪胎，

An individual American produces 729 kilogrammes of garbage per year

一個美國人一年會丟 729 公斤的垃圾，

of which 544 kilograms is organic waste.

其中有 544 公斤是有機廢物。

This means that the population of America which is roughly 5% of the world, generates 40% of the world's waste.

這代表美國人口大約佔了世界的 5 %，卻製造了世界 40 % 的垃圾。

For most of the world, the American Lifestyle would mean living longer.

對世界上大多數人來說，美式生活代表的是長壽。

The U.S. life expectancy is 82.1 years for women, and 77.5 for men.

美國對於女性的預期壽命是 82.1 歲，男性則是 77.5 歲。

But it still only ranked 42nd in the world behind other industrialized nations like Australia and Canada.

美國只排在世界第 42 名，落後其他工業化國家像是：澳洲和加拿大。

This is likely because these countries have better publicly funded health care.

可能是因為這些國家有較好的公共醫療保健資助。

The median age in the United States is 37.9

美國的中位數年齡是 37.9 歲

meaning if you divided the whole population of America into two equal groups,

意思就是，如果把美國總人口平均分成兩個部分，

half of the people would be younger that 37.9,

一半的人會小於 37.9 歲，

and half of the people would be older.

另一半的人就會大於這年齡。

America is defined as having an ageing population in that the world's median age is lower at 30.1.

因為世界的中位數年齡低於 30.1 歲，所以美國現在確定人口開始高齡化。

Niger has the lowest median age at 15.3 years old,

尼日爾有著最低的中位數年齡 - 15.3 歲，

compared to Japan, where the ageing population could become an issue

與有人口高齡化問題的日本相比，

as their median age is 46.9.

他們的中位數年齡是 46.9 歲。

The lifestyle of an American requires about ten liters of oil per day.

美國人的生活方式每天需要十公升的油。

But some other developed countries consume even more on average, like Canadians, who use 10.2 litres per day,

但其他已開發國家消耗量就高於平均，像是加拿大人，一天就消耗 10.2 公升的油，

while some of the lowest consumers of oil are Bangladeshis who only use 0.1 litres per day.

然而孟加拉人一天消耗最少的油，他們只消耗 0.1 公升。

A direct way of measuring the impact of the worlds witching to an American lifestyle is using the global hectare.

有一個直接的方式可以測量美式生活對世界的影響，那就是用全球公頃。

This measurement looks at how much land, sea and other natural resources are needed to produce what each person consumes per year.

這個測量方式是看每人每年的消耗量，需要用到多少的土地、海洋或其他自然資源。

For example: the rice they eat, the shelving unit they buy, or the clothes they wear.

舉例來說：他們吃的米，他們買的架子，或是他們穿的衣服。

The average person in the world uses 2.7 global hectares per year.

世界平均每人每年會用到 2.7 全球公頃。

The highest is the lifestyle of those in Kuwait who use 8.9 global hectares annually,

科威特人是使用最多公頃的，每年會用到 8.9 全球公頃，

with the U.S. trailing slightly behind with 6.8 global hectares per year.

而美國每年用到 6.8 全球公頃，以些微差距緊跟在後。

With the amount of CO2 released from this,

大量的二氧化碳也從中釋放，

studies show that we would need another half of an Earth

研究指出，我們還需要一半的地球

in order to absorb it at a safe rate.

以安全的速率來吸收二氧化碳。

Although other studies suggests that these are underestimations.

然而，其他研究建議這些都還是低估了。

So you can imagine if we were all living like Americans,

所以你可以想像，要是我們都像美國人一樣生活，

it would be catastrophic.

一切都會變成災難。

In fact we would need 4.1 Earths in order to sustain everyone living like an American.

事實上，我們還需要 4.1 個地球，才能讓大家都像美國人一樣生活。
