Quote:Synopsis
The tropics are not only the birthplace of humankind but also home to 10 percent of the world's population, including 5 of the 10 most-populated countries. However, the region is not solely defined by its location; rather, its uniform weather and climatic characteristics-hot and humid throughout the year; little seasonal variation in temperature or precipitation; large amounts of annual precipitation, with no period of pronounced drought; and the world's highest annual average temperatures-set it apart from other environments. Due to its wet climate, the tropical realm is also characterized by dense rain forest vegetation cover and agriculture that never requires irrigation.
