Parth Patel Mr. Herzog pr.6 11/6/15 Apes Chapter 23 questions 1. Public Lands are classified as (1) multiple-use, (2) moderately restricted-use, (3) restricted-use, (4) multiple use lands, and (5) National Lands. Wise-Use movement is a loose confederation of individuals and groups that coalesced in response to the increasing success of environmental advocacy. 2. Old growth forests are uncut or regenerated forests that have not been seriously disturbed by human activities or natural disasters for at least a couple centuries (Willamette National Forest). Second-growth forests consist of a stand of trees that resulted from natural secondary succession, because of human activities or natural forces (Stanley Park, Vancouver, Canada). A tree farm is a managed tract with uniformly aged trees of one or two genetically uniform species that are harvested by clear cutting (Calusa Creek Tree Farm). 3.Forests are important because 1. fuel wood 2. logging (buildings and what not) 3. commercial trade 4. creation of biodiversity 5. erosion prevention of soil and mudslides 1.to prevent soil erosion. 2.To reduce pollution. 3.To protect wild life. 4.Gives food & medicine. 5.protect from global warming. 4.Estimates of global tropical forest loss vary from 50,000 square

kilometers (19,300 square miles) to 170,000 square kilometers (65,600 square miles) per year. This rate is high enough to lose or degrade half of the world's remaining tropical forests in 35-117 years. A 2006 survey found that less than 5% of the world's tropical forest are managed sustainably. The primary causes of tropical deforestation and degradation are population growth, poverty, environmentally harmful government subsidies, debts owed to developed countries, failure to value their ecological services, and secondary causes explain why there is so much variation among estimates since the environment for the seeds within each tray is identical, the genetic diversity of the seeds must account for the observed height differences, so the heritability within each tray is very high, probably close to 1. Yet the heritability between the trays is very low since the environments are so disparate and the genetic material is similar. The large observed differences in height between the trays are due to environmental differences. list 5 ways that tropical forests touch lives in the temperate zones 1. medical benefits such as herbal remedies 2. home to many animals which become extinct with deforestation 3. create and maintain moisture in the amazon

4. chemicals needed to create everyday things such as sanitary toothpaste 5. prescription drug needs summarize the impact of deforestation on some of the world's indigenous cultures Deforestation fails to provide a sufficient number of trees to effectively absorb and release water, so waterways dry up, soils erode, crop yields shrink and famine results.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
