Transcript of SI Bio 211 Thursday, December 11, 2008 Jenny F.. Compare the growth rate to population doubling...
Compare the growth rate to population doubling times.
-What do these two terms tell us?-Do they share the same trend?
• Describe what we know about number of species.– How many are there?– How many are estimated?– Are we still discovering new phyla, species, etc.?
True or false:1.Humans are monopolizing Earth’s resources2.Humans haven’t altered the atmosphere3.It is very likely that humans have decreased
species extinction rates.4.The climate is changing.5.Natural species and ecosystems directly
benefit human societies in many ways.
