The issue of safety in the classroom is rarely considered at such a foundational level. Considering that a participant on a playground can break a leg, or worse, safety occupies a central role in a designerâs thinking.
The Amazon basin is the largest drainage basin in the world, about 7,050,000 square kilometres (2,720,000 sq mi), and accounts for approximately one-fifth of the world's total river flow.he Amazon River and its tributaries are characterized by extensive forested areas that become flooded every rainy season. Every year, the river rises more than 9 metres (30 ft), flooding the surrounding forests, known as varzea (vÃ¡rzea flooded). forests
The effects of the Amazonâs continued destruction could be especially severe in southern Brazil, where much of the countryâs agriculture, industry and population is based. About 40 percent of the precipitation there comes from moisture evaporated off the rain forestâs thick tree cover. Cutting back more of the Amazon could mean starving the area of water. âThe hydroclimatic cycle of the Amazon really depends on having forest there,â said Thomas Lovejoy, president of the U.S.-based H. John Heinz III Center for Science, Economics and the Environment.
