Cultural adaptation has made humans one of the most successful species on the planet.Through history, major developments in technology, medicine, and nutrition have allowed people to reproduce and survive in ever-increasing numbers.The global population has risen from 8 million during the Ice Age to about 6 billion today.
However, the successes of culture adaptation can also create problems in the long run.Over the last 200 years, people have begun to use large quantities of natural resources and energy and to produce a great amount of material and chemical wastes.The global population now consumes some important natural resources—such as petroleum, wood, and minerals—faster than nature can produce them.Many scientists believe that in the process of burning fuels and producing wastes, people may be changing the global climate in unpredictable and possibly harmful ways.Thus, the adaptive success of the present-day global culture of production and trade may be temporary.
