- Abstract：
In many respects New Zealand is a very young country. Its economic history has been short. But, short though it is, the transformation achieved is profound. What Europe took in twenty centuries, and in North America four, has been accomplished in New Zealand within a single century—in little more than one full lifetime. Although extensive and achieved with remarkable speed, this accomplishment can scarcely be regarded as permanent. Destruction of natural vegetation, animal life, and soil properties has been widespread, and nature’s revenge is already in evidence—and at an ever accelerating rate.
