Aim How is Deforestation and Direct Harvesting Harmful

Aim: How is Deforestation and Direct Harvesting Harmful to Earth’s Ecosystems? DO NOW This is a Columbian parrot. 1. Would you bring it with you, to the U. S. , to have as a pet? Why or why not? 2. Would this parrot suffer, if moved from its original location?

Deforestation • Destroying forests or plowing through meadows Why do this? • Space for apartment buildings, stores, parking lots, farms

Effects of Deforestation • Reduction in Biodiversity organisms killed or will have to migrate or move to another location • Ecosystem & Food Web Disruption, whether it be a forest or a meadow • Increase in the amount of CO 2 being released into the atmosphere • Increases amount of soil erosion & makes soil less fertile • Change of climate : decreased rainfall

Solution to Deforestation • Try not to destroy the habitat (forest or meadow) • Cut down fewer trees • Replant trees that have been cut down

Direct Harvesting • Destroying or removing a species from its habitat Why do this? • Humans exploit wild plants & animals for their products • Using them as pets

Examples • • Elephants or walruses for their ivory tusks Baby Seals for their pelts Tropical rainforest trees for plywood Columbian parrots for pets in U. S. passenger pigeons for hunting purposes Dodo birds for hunting purposes Blue whale for hunting purposes
