4. How human threaten biodiversity… Human activity in habitats can create ecological hot spots. These are areas which have traditionally had lots of biodiversity but have lost much of that biodiversity due to human activity.

5. How humans threaten biodiversity… DIRECT THREATS: Unregulated sport hunting Accidental killing Commercial harvesting Harassing Poisoning Collecting

6. How humans threaten biodiversity… INDIRECT THREATS: Pollution Invasive species Damming Deforestation Urbanization Agriculture conversion

7. Why is it bad to have small populations? 1.Environment unpredictability: population is so small that natural catastrophes, weather, resource shortages, and predators could cause an extinction 2.Genetic unpredictability: population is so small that inbreeding occurs 3.Demographic unpredictability: population is so small that opposite genders are difficult to find

8. New roads are built and cut off small populations from one another Inbreeding increases in the isolated populations Fewer individuals are born and more die because of inbreeding depression Isolated populations Become smaller

9. An increased proportion of the population is killed by hunters Fewer individuals are left in the population Fewer animal are around to be hunted Fewer new animals are born
