Presentation transcript:

Warm-Up3/31/15   What is a catastrophic event?  Give 3 examples of natural events and 3 examples of man-made events.

 Destroys plants in the area  Kills animals or their habitats  Releases contaminated materials from buildings  Soil erosion, water pollution  Dangerous emissions from burning debris Effect on Ecosystem: Tornado

Effect on Ecosystem: Flood  Polluted runoff will be carried back into water  Plants and animals may drown, throwing off the food chain

 Aquatic (water) Ecosystems:  Mixing of salt and fresh water  Polluted runoff goes back into the water  Terrestrial (land) Ecosystems:  Soil erosion  Kill mangrove forests; birds cannot rest there anymore  Destroys sea grass beds Effect on Ecosystem: Hurricane

 Kills native plant species  Allows opportunity for invasive plants to take over  Increase carbon dioxide levels in the atmosphere  Increased soil erosion due to flash floods Effect on Ecosystem: Wildfire
