The researchers further warn that increasing temperatures in this vital, globally-extended ecosystem could “reduce the transfer of primary produced organic matter to higher trophic levels” (e.g., such as those that sustain corals and the many species that use them as habitat), interfere with the global carbon pump, and possibly set up a positive feedback mechanism, further increasing atmospheric carbon dioxide.

Unrestricted expansion of rubber tree plantations in South East Asia could lead to “devastating environmental effects”, according to authors Ziegler, Fox and Xu writing in a May, 2009 perspective article in Science.

Throughout the “montane” (foot hill and low mountainous) mainland of South East Asia (inclusive of Thailand, Vietnam, Cambodia, Laos, Myanmar, and China), rubber plantations are expanding. So far, an estimated half million hectares have been planted, and by 2050, that land mass area could triple. This expansion will come at a cost to broad leaf, evergreen forests and “swidden” areas (with vegetation from older slash and burn efforts).
