**** Rainforests by Michael G. 2001 In an average year the climate in a tropical rain forest is very humid because of all the rainfall. A tropical rainforest gets about 150 cm of rain per year. It gets lots of rain because it is very hot and wet in rain forests. The hotter the air, the more water vapor it can hold.
Brazil is the worldâs biggest coffee grower and exporter, and the size of its annual harvest can have a strong effect on world prices. Coffee exports generated $5.15 billion in revenue for Brazil in 2013, a decline from $6.36 billion in 2012, when the price of coffee was higher.
Coffee is a major export commodity: it was the top agricultural export for twelve countries in 2004, the world's seventh-largest legal agricultural export by value in 2005, and the second most valuable commodity exported by developing countries, from 1970 to circa 2000.offee cultivation first took place in Ethiopia. The earliest credible evidence of coffee-drinking appears in the middle of the 15th century in the Sufi shrines of Yemen. In the Horn of Africa and Yemen, coffee was used in local religious ceremonies.
