The energy resources available to our species was added to by natural gas, hydroelectricity, and nuclear power. The production of goods and services was immensely increased by modern science and technology. The natural order was always altered by human activity, but now the scale of that impact assumed geological and global proportions. The doubling of cropland was led to by the growing consumption of the rich and the growing numbers of the poor, which also led to dramatic increases in the rate of erosion. At the hands of humankind, massive species extinctions is happening. In environments shaped by human action is where 90 percent of all plant activity now occurs.
