- What is the connection between natural capital, natural income, and an environmentally sustainable societyoner Alt oX an H2 tre qu de ult ap m © Sally A. Morgan/Ecoscene/CORBIS b 29. According to the Costa Rica Rainforests Outward Bound School, the rain forests of the world are disappearing at a rate of 80 acres per minute, day and night. In December 2000, 53,694,993 acres of rain forest were destroyed. Which of the following facts illustrates the negative effect of their destruction on the environment? p a about rain forests A. The soil of the rain forest is low in nutrients, so farmers cannot reuse the same land every year. B. Ranchers clear and use the land for pastures for their cattle because land is inexpensive. C. Trees from the rain forest are used to supply the growing population with lumber for homes and furniture. D. The release of carbon dioxide into the air during the burning of the rain forests adds to the greenhouse effect. E. Almost half of the tropical rain forest deforestation occurs in South America.This conceptual model to the right shows the flow of energy through a spring ecosystem in Silver Springs, Florida from Figure 46.8 in your textbook. 7a.
