Understanding Sustainability: From Definition to Reality

Four short lessons explore what sustainability really means — from widely accepted definitions to the real-world challenges we face today. A balanced, practical take on the pressures, deficits, and goals shaping our world.

🌍

Lesson Overview

Sustainability is often treated as a buzzword — but at its core, it’s about balance.

In this four-part microlearning lesson, we explore:

  • 📌 A practical definition of sustainability — and why “balance” captures it best
  • 📌 How today’s challenges stem from the design of our economic system
  • 📌 What Earth Overshoot Day reveals about the rate we consume natural resources
  • 📌 Why the SDGs are off track — and what that says about global follow-through

These lessons are designed to help you grasp the essence of sustainability — clearly, and without the noise.
