What Is Sustainability?

Req 1 — Defining Sustainability

1.
Describe the meaning of sustainability in your own words. Explain the importance of sustainability to society and how you can contribute to fulfilling the needs of current generations without compromising the needs of future generations.

What Does Sustainability Mean?

At its core, sustainability is about balance. Imagine a bank account. If you keep withdrawing money without ever making deposits, eventually you run out. Earth’s resources work the same way. Sustainability means using resources — water, soil, energy, forests, minerals — at a pace that lets them replenish, so future generations have what they need too.

The most widely used definition comes from the United Nations’ 1987 Brundtland Report: “Meeting the needs of the present without compromising the ability of future generations to meet their own needs.” That single sentence shaped how governments, businesses, and communities think about the future.

But sustainability is not just about the environment. It rests on three connected pillars:

When all three pillars are strong, a society is sustainable. When one is weak, the others eventually suffer too.

Why Sustainability Matters to Society

Think about the resources you used just today. The water in your shower came from a river, lake, or underground aquifer. The electricity powering your phone was generated by burning fuel, splitting atoms, or capturing sunlight. The food on your plate traveled an average of 1,500 miles to reach you.

Now multiply that by 8 billion people. Every day, humanity uses enormous quantities of water, energy, and materials. Some of those resources — like solar energy and wind — are renewable. Others — like fossil fuels and certain minerals — are not.

Sustainability matters because:

How You Can Contribute

You do not need to be a world leader or a scientist to make a difference. Sustainability starts with everyday choices:
