Heat-trapping gases allow ecosystems to flourish. The atmosphere is what makes the Earth habitable. Scientists Paul Hoffman and Andrew Knoll look at these clues to help explain the rise of complex animal life. Ancient rocks provide evidence of the emergence of oxygen in the atmosphere and of a frozen Snowball Earth. The early Earth was a much different planet than the one we know today.

The unit textbook chapters provide core content reading that extends and deepens concepts introduced in the video case studies. Each unit is composed of a 30-minute video, each featuring interviews with two scientists who are carrying out important research in environmental science, and an online text chapter. The Habitable Planet is a multimedia course consisting of 13 units. Each of the 13 programs features two case studies following top scientists in the field. Topics include human population growth and resource use, increasing competition for fresh water, and climate change. Following this introduction, the course explores the effect that human activities have on the different natural systems. This course begins with an overview of the EarthвЂ™s systems - geophysical, atmospheric, oceanic, and ecosystems - as they exist independently of human influence. This course asks: What makes Earth unique among planets? How are life forms, namely human beings, sustained by the EarthвЂ™s overall ecosystem, and, in turn, what effects do humans have on its natural systems? What does EarthвЂ™s future look like? Given current trends, what can be predicted and what might be expected if we acted in concert to mitigate our impacts on the planet itself?

The conditions present on Earth are maintained within a reasonable range by a series of global cycles linking geological systems with diverse forms of life present in almost every available niche.

The Earth is probably unique in our solar system-a rare platform for complex life forms.
