Our world is changing, the climate is changing. Species that have long existed on our planet are disappearing and resources are becoming scarce. People are slowly realizing that development is not always good. We are exploiting our earth, but we should be looking after it, because we only have this one. Slowly, however, a rethink is taking place and people are trying to undo past mistakes. Attempts are being made to reduce CO₂ emissions, conserve the earth's resources and pay more attention to nature. But once we have become accustomed to a certain standard of living, it is difficult to give it up again or change our habits.

This book addresses the main problems facing our planet, discusses topics such as climate change, agricultural use, the energy transition and the extinction of species and gives advice and tips on how each individual can help to do something good for nature and the environment. It is up to everyone to make the world a better place.
