Jenny F.
Compare the growth rate to population
doubling times.
-What do these two terms tell us?
-Do they share the same trend?
What is the carrying capacity?
What impacts do humans have due to increasing
population size?
What is net primary productivity?
How do humans use NPP?
• 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 resources
2. Humans haven’t altered the atmosphere
3. 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.
