RUBBER TREES Meaning and
Definition
-
Rubber trees are tall evergreen plants primarily cultivated for their sap, which is the primary source of natural rubber. Scientifically known as Hevea brasiliensis, rubber trees belong to the family Euphorbiaceae. They typically grow up to 100 feet (30 meters) in height, exhibiting a straight, cylindrical trunk with a dense, rounded crown of glossy green leaves.
The latex sap from rubber trees is extracted through a process called tapping, where an incision is made in the bark to allow the milky fluid to flow into collection cups. This sap consists of a complex mixture of organic compounds, primarily polymers of isoprene, which solidify upon exposure to air, forming the familiar rubber material. Known for its elasticity, durability, and resistance to water, rubber is a versatile material widely used in the production of various consumer and industrial goods.
Rubber trees are native to the Amazon rainforest in South America but are now extensively cultivated in tropical regions around the world, including Southeast Asia and Africa. These trees prefer humid and tropical climates with well-drained soils. They typically require temperatures between 68-95°F (20-35°C) and high annual rainfall for optimal growth.
In addition to their economic importance as a source of natural rubber, rubber trees also provide environmental benefits. The vast plantations of these trees contribute to carbon sequestration and help combat global warming. They also support diverse ecosystems, providing habitats for numerous species of plants and animals.
Etymology of RUBBER TREES
The word "rubber trees" is derived from the material they produce, known as "rubber". The term "rubber" comes from the English term "rubber", which was initially used to describe the action of rubbing or erasing pencil marks. In the late 18th century, English chemist Joseph Priestley discovered that the sap of the South American tree Hevea brasiliensis was an effective eraser and named it "rubber". The name "rubber" eventually expanded to refer to the material produced from the rubber tree itself, and the term "rubber trees" emerged as a result.
