Prepare a summary of this article without distorting the message it wanted to convey For farmers, pesticides save labor and generally provide a higher yield: they can mean the difference between saving a crop and losing it to disease. Some farmers, especially those who grow produce at a smaller scale, use pesticides sparingly. For example, fruit trees are susceptible to disease in northeastern regions, especially at the blossom stage. An apple or peach grower may spray their fruit trees with a fungicide once in the spring to ensure that the fruit sets, but use no further chemicals for the rest of the season. For many large row crop farmers, on the other hand, regular pesticide use is as much a part of farming as planting seeds. Spraying Roundup on a field of corn genetically engineered to withstand the chemical kills! the weeds without affecting the corn. In comparison to mechanically weeding hundreds or thousands of acres, using pesticides is a game-changer. Some farmers spray their…

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 about rain forests illustrates the negative effect of their destruction on the environment? 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.

4. Maple syrup is harvested from many species of maple trees, Acer sp, but in order to tap into the syrup, one must drill 2 to 2.5 inches into the tree trunk. Furthermore, the syrup can only be collected after a time of hard freeze, followed by several sunny days with temperatures in the 40s, early in the spring. Based on this description, what part of the tree is specifically being tapped and why it can only be tapped under these conditions?
