Why rubber is called equatorial crop?

Rubber is called an equatorial crop because it thrives in the warm, humid climates found near the equator, typically between latitudes 30°N and 30°S. These regions provide the optimal temperature, rainfall, and humidity levels necessary for the rubber tree (Hevea brasiliensis) to grow and produce latex. The consistent climate in these areas supports the tree's growth cycle and enhances latex yield, making equatorial regions ideal for rubber production.
