Lectures We'll View During This Session

Full course details:

5: Climate and Habitat—Twin Ecological Crises

Apply what you learned in the last lecture about the forces of change within the Earth's ecological system to understand two crucial aspects in today's world: climate change and habitat destruction.

6: Human Society as Ecological Driver

Human power structures, social organization, information flow, and cultural practices can profoundly change the shape of ecosystems. Examine the role of humans as "ecosystem engineers" as you look more closely at some of the social forces and practices that affect the ecology of our planet.

7: Movement of Energy through Living Systems

Begin your consideration of specific forces that cause ecosystem change by examining the flow of energy. You trace how energy moves through ecosystems, from sunlight through the transitions of food production, consumption, and decomposition.

8: Humans as Energy Consumers

Humans are the most voracious consumers of energy on the planet, and our appetite for energy produces enormous short- and long-term challenges to ecological sustainability. Investigate human energy consumption habits and examine alternatives to traditional ways of accessing energy.

Hope to see you there!

    I just saw this. Seemed relevant not to the topic, but to this meetup :-P

I decided to start Reno Motorcycle Riders Group because I wanted to be part of a group of people who enjoyed my passion... I was excited and nervous. Our group has grown by leaps and bounds. I never thought it would be this big.
