Photographer's Note

Despite being a native plant from Brazil, Asia produces about 90% of natural rubber today. The world largest natural rubber producer currently is Thailand, followed by Malaysia and Indonesia. Shown in this picture is the collection of whitish to yellowish Latex from the at least 5 years old rubber tree, which is the main ingredient of natural rubber. In contrast synthetic rubber is made from polymers.

Originally, rubber trees grew only in the Amazon region of South America -rubber trees can grow up to 30 meters high. When vulcanization was discovered in 1839, demand for rubber increased. Rubber tree seedlings were exported from Brazil to India in 1873 by the British to propagate the tree but the rubber tree seedlings did not survive. But future attempts to export the rubber tree seedlings to Ceylon, Singapore, Malaya (now Malaysia) were successful and today, most of the rubber tree plantations are in Southeast Asia, Central America and Africa.
