Title of notes: Loss of biodiversity p. 24 RS

I’ll know I’ve got it when… Learning target I can determine what causes the loss of biodiversity. Today I am… Learning about what threatens biodiversity . So that I’ll be able to… Understand the impact of biodiversity being lost. I’ll know I’ve got it when… I can explain the impacts of biodiversity loss on Trevor Browne campus and connect it to the world.

Biodiversity Loss Biodiversity being lost happens naturally Extinction occur one by one Fossil record shows 1 in every 1000 mammals would go extinct every 1,000 to 10,000 years Five mass extinctions have occurred in Earth’s history Mass extinction: global decrease in the diversity of life forms

Other causes of biodiversity loss….. Habitat change and loss Invasive species Pollution Overharvesting Climate change

Habitat change and loss Clearing forests by logging companies Removes food Removes shelter Removes other resources that organisms need to survive

Invasive species Introduction of non-native species to an environment Thrive in new environment Over populate because lack of predators and competition Cause some native species to go extinct Can cause economic damage Zebra mussel

Pollution caused by industries Chemicals, heavy metals, pesticides, and toxic chemicals Pollute water and air Poison and kill humans and wildlife Pollution caused by industries Cough! Cough!

Overharvesting Hunt, fish, or harvest a species quicker than it can replenish Poaching overfishing Siberian Tiger population decline due to hunting Upset Siberian Tiger Poaching: illegal capture or killing an organism.

Climate change Effects habitats Extreme weather events Warming temperatures Increases the chance of plants and animals going extinct Environments are changing to quickly for organisms to adapt. Sad Polar Bear

Something to ponder…… Are we looking at a sixth mass extinction?
