The rubber tree is one of the crucial plants in Indonesia which is widely found in Sumatra. Indonesia is the largest rubber-producing country globally, contributing 26% of the world's total natural rubber production. In addition to producing latex as the main ingredient for making tires, rubber trees also absorb exhaust gases and have much more optimal oxygen. This plant also absorbs carbon dioxide gas which is processed into a carbon source for photosynthesis. This natural process is beneficial in reducing the greenhouse effect such as global warming and environmental damage.
