Public Service Announcement: The Affects of Deforestation on Biodiversity By: Mariel Sass and Abby Spector

What Is The Problem? • deforestation is decreasing the biodiversity on Earth • deforestation: removal of a forest or trees to build a building or to be used for paper • biodiversity: variety of organisms in an ecosystem that can be used to determine the health of an environment • the forest is home to many animals • food chains will greatly be affected • without one animal, its predators will run out of food and the animals it eats will grow as a population.

Is There Anywhere In Particular That Is Being More Heavily Affected? • rainforests are greatly affected by deforestation • destroys the natural habitats of 50 -90% of all organisms • tropical rainforests: home to over 50 million organisms & 50 -100 of the different organisms are lost everyday.

How Are We Causing It? • building roads • malls • houses • resorts • supplies (paper and wood)

Possible outcomes if not stopped or prevented? • organisms that live in forests and rain forests will be wiped out • trees and plants won’t be there to give us oxygen • animals can go extinct If we do stop… • there will be a lot more organisms living because we are the main source of deforestation

What is the environmental impact of deforestation on biological diversity? • we cut down numerous trees to build resorts and roads • animals eat plants and leaves on trees • forced to move somewhere else • chain reaction • Stewart Smith who wrote “The Effects of Deforestation on Animals” claims that when deforestation happens: increases the chances of the species becoming extinct • the value of a tree alive is greater than when it is dead • trees have a never ending cycle of taking in carbon dioxide and putting out oxygen • snowball into a bigger problem: animals move into different areas and possibly mix in with suburban or urban life when they don’t belong there.

Other human interferences • factories and other big buildings are opening up more opportunity to create more air pollution • if roads are created it makes more air pollution with emission from cars

Ways We Can Help in Our Dayto-Day Life 1. Reduce Your Consumption of Paper Products • buy organic • buy reusable 2. Think Twice before Printing • email! 3. RECYCLE • recycle paper

How Does Deforestation Impact Natural Biogeochemical Cycles? Carbon • trees take in CO 2 in order to do photosynthesis • there isn’t as much carbon intake • creates more of a “greenhouse” effect • carbon traps heat in our atmosphere. • Trees help regulate the carbon and oxygen levels, and without them, the levels are abnormal
