The Rubber Tree, also known by its scientific name Hevea brasiliensis, is a tropical tree native to South America. It is most commonly found in Brazil, but it is also found in other parts of South America and in India. The tree produces a milky white sap called latex, which is used to make rubber. The ULE is an acronym for the United Nations Environment Programme, which works to protect the environment and promote sustainable development. HULE stands for High-Performance Liquid Chromatography, a technique used to separate and identify components of a mixture. India is the world's largest producer of natural rubber, with over 90% of the world's rubber coming from India.
