The distribution of plants and animals around the world corresponds closely to global patterns of temperature and rainfall. This is why two forests half a world away from each other will often have very similar organisms living in them. In this ZOOMSci video segment, a cast member of ZOOM creates a self-contained biome and explores evaporation, condensation and precipitation.

There are times when our role as energy consumers is clear. For instance, when we fill our cars' fuel tanks, the amount of money we spend makes it obvious how much gas we are using. But what we seldom think about is the energy we consume by simply living our lives in a developed society. In this video segment adapted from NOVA/FRONTLINE, experts estimate the amount of energy that is burned during daily activities, and how much CO2 those activities contribute to the atmosphere.
