(22) Students’ presentation The threat to: FOREST WATER BIODIVERSITY (23) • Using up natural resources before they can be renewed (over-fishing in oceans, or over-harvesting trees on land) • Habitat destruction like clearing forests or draining wetlands for towns or agricultural purposes • Releasing invasive species into foreign ecosystems (like the cane toad in Australia or the zebra mussel in the Great Lakes or yellow snails in our country ) • Any kind of pollution (water, air, soil, etc) • Failure of food chains (24) Students’ presentation The solutions of: FOREST WATER BIODIVERSITY (25) • You can volunteer at a nature center, park, or a zoo (26) • Be careful not to buy coral, ivory, or products made from animals They come from endangered species (27) Buy organic produce (28) • Add mulch to soil to prevent erosion (29) • Don’t use pesticides; they can kill plants and animals (30) • Stop junk mail to save paper and protect our forests (31) • Use cloth napkins and cotton handkerchief instead of paper ones (32) • Recycle old newspaper and buy recycled paper products (33) • Use e-mail since it saves paper (34) • You should always use eco-friendly cleaning products (35) ow Can You Help? • You can volunteer at a nature center, park, or a zoo • Buy organic produce • Add mulch to soil to prevent erosion • Don’t use pesticides; they can kill plants and animals • Stop junk mail to save paper and protect our forests • Use cloth napkins and handkerchiefs instead of paper tissues • Recycle old newspaper and buy recycled paper (36) THE END (37)
