摘要: Human activities have profound impacts on our planet, but these can be difficult to measure accurately. In 1986, an influential study used the fraction of Earth9s total plant growth or net primary production that is appropriated by humans as a measure. his Perspective, Field discusses reassessment this value by Rojstaczer et al . and highlights ways in which estimates human further improved.
