The first rubber tree only grows in South America. After repeated experiments conducted by Henry Wickham, this tree was successfully developed in Southeast Asia, where it is currently widely developed. Now Asia is a source of natural rubber.
The green nature is filled with rubber trees, we visit many rubber trees in Kalimantan, the rubber trees in Borneo as a money changer for some people.
