Unit 3 Life on Earth

Unit Introduction

In this final unit of the course we step back and consider the question 'how do we fit in?' We'll start off by learning about species and ecosystems, how these can be studied, and how they have come about. We'll then conclude by considering ways in which we as a species have impacted upon our environment. 

As you're hopefully aware, the impact of humans on the planet's ecosystems couldn't be more relevant or pressing. It is crucial that we therefore learn about these issues, but we also need do something about them too.
