According to the Stockholm Resilience Centre, the two core boundaries of the nine planetary boundaries are:
选项：
A.
biosphere integrity and climate change
B.
climate change and land-system change
C.
biosphere integrity and land-system change
解释：
A is correct. The Stockholm Resilience Centre has identified nine planetary boundaries within which humanity can continue to develop and thrive. Two of these—climate change and biosphere integrity—are deemed core boundaries, for which significant alteration would “drive the Earth system into a new state.”
Stockholm Resilience Center 的 Nine Planetary Boundaries包含Climate change, biosphere integrity, land-system change. Nine planetary boundaries are
1. Climate change
2. Change in biosphere integrity (biodiversity loss and species extinction)
3. Land-system change (e.g. deforestation)
4. Freshwater change
5. Biogeochemical flows (phosphorus and nitrogen cycles)
6. Ocean acidification
7. Atmospheric aerosol loading
8. Stratospheric ozone depletion
9. Introduction of novel entities (emissions of toxic compounds, such as synthetic organic pollutants and radioactive materials)
