With roughly 7.9 billion people living on Earth, human consumption of the world's natural resources has become a hot topic.

地球上生活著大約 79 億人，人類對世界自然資源的消耗已成為一個熱門話題。

The more people there are, and the richer their lifestyles, the more resources are consumed.

人越多，生活方式越豐富，消耗的資源就越多。

We need food and water to survive, but what if these resources disappeared?

我們需要食物和水才能生存，但如果這些資源消失了呢？

The Global Footprint Network wants to raise awareness of this concern.

全球足跡網絡希望提高人們對這一問題的認識。

To do so, it started the Earth Overshoot Day, EOD, project.

為此，它啟動了 "地球超重日"（EOD）項目。

EOD is the date each year when our ecological footprint exceeds the quantity of resources the Earth is able to provide.

EOD 是每年我們的生態足跡超過地球所能提供的資源數量的日子。

The date of EOD changes every year.

EOD 的日期每年都有變化。

Scientists determine it by studying several factors.

科學家通過研究幾個因素來確定它。

First, they measure how long it takes the Earth to regenerate these resources.

首先，他們測量了地球再生這些資源所需的時間。

This is called world biocapacity.

這就是所謂的世界生物能力。

They divide that number by our human footprint, or how much of these resources we regularly consume.

他們用這個數字除以我們的人類足跡，也就是我們經常消耗的這些資源的數量。

In the end, they reach the date of EOD after multiplying the result by 365.

最後，將結果乘以 365，得出 EOD 日。

In 2020, we reached EOD on August 22, which was later than in previous years.

2020 年，我們在 8 月 22 日達到 EOD，比往年晚了一些。

In 2021, it came on July 29.

2021 年是 7 月 29 日。

Every year, Global Footprint Network hopes to push EOD further into the year.

每年，全球足跡網絡都希望將排爆活動推向新的一年。

Every time we hit EOD before the end of the year, we're taking up resources that should be saved for the future.

每次我們在年底前進行 EOD，都會佔用本應留給未來的資源。

To help people move the date later into the year, the Global Footprint Network's hashtag MoveTheDate campaign promotes ways of reducing our footprint.

為了幫助人們將這一日期延後到今年，全球足跡網絡發起了 "移動日期"（MoveTheDate）活動，宣傳減少足跡的方法。

Think about where your impact on the environment comes from.

想想你對環境的影響來自哪裡。

Try eating local foods, using more public transportation, and buying greener products.

嘗試食用當地食品，更多地使用公共交通工具，購買更環保的產品。

It will take action around the world and at every level of society to take on the problem of climate change, but with your participation, we can start pushing EOD a little later each year.

要解決氣候變化問題，需要全世界和社會各個層面的行動，但有了您的參與，我們就能每年晚一點開始推動排爆。

That way, we'll make sure there's enough to go around and have some left over for future generations.

這樣，我們就能確保有足夠的食物，併為子孫後代留下一些。
