Extinction

Extinction, a natural process that has occurred throughout world history, takes place when an organism is unable to adapt to a changing environment or to compete with better adapted species. In recent times, human have become the major threat to the survival of many plants. Technological developments in industrial nations and increasing pressure for agricultural land in developing countries, combined with the exploitation of timber, minerals and other natural resources, are causing rapid enviroment changes. Because destruction of habitat is now the principal cause of endangerment, habitat protection is the only effective way to save plants from extinction. John Morton said: “ Plants are a part of our natural heritage – a heritage that we have an obligation to preserve for the benefit of future generations of mankind.”. Therefore, we cannot let plants become extinct.(HOAI THONG)
