Area deforested (square kilometers) chows the area of land deforested in square kilometers for each year from 1995 to 2013. (i) Determine the year in which there was the greatest decline in deforestation, based on the graph shown. (ii) Determine the percent reduction in the amount of land deforested during that year. (ii) Identify and discuss TWO reasons why tropical rainforests might be under pressure of deforeslation in Brazil. (iv) Identify and discuss TWO benefits, either ecological or economic, of leaving forests intact. h) Forest fires are a part of the natural life cycle of a forest. Surface and crown fires can affect forest ecosystems. (i) Identify and discuss TWO ecological benefits of surface fires. (ii) When fires are suppressed for long periods of time, a crown fire can result. Explain why a crown fire is especially devastating. (iii) Discuss ONE strategy that could be used to prevent crown fires. Brazil Deforestation Rates 35,000 30,000 25,000 20,000 15,000 10,000 5,000 2015 2010 01 2005 2000 1995 Year
