Just about all of Southeast Asia is warm and wet. Rainforests and tropical grassland cover most of this region. Over time, much of the rainforest has been cleared to raise crops that do well in the tropics. People grow rice, sugarcane, tea, and rubber.
Many types of bamboo grow well here. Bamboo is a grass. But unlike most grasses, it can grow to huge sizes. Some types of bamboo may reach over 100 feet high and have stems a foot in diameter. Bamboo stems are made into everything from houses to tools. Bamboo probably has more uses than any other plant in tropical areas.
