    Humans have changed all of Earth’s ecosystems.

    • Huge areas of forest have been converted to cropland

    • Between 1960 and 2000, reservoir storage capacity quadrupled, and as a result the amount of water stored behind large dams is estimated to be three to six times the amount of water flowing through rivers at any one time

    • Almost half of the planet’s mangroves have been lost in the last two decades

    • 20% of known coral reefs have been destroyed and another 20% degraded in the last several decades

     Roughly 10–20% of current grassland and forestland is projected to be converted to other uses between now and 2050, mainly due to the expansion of agriculture and the expansion of cities and infrastructure. Globally, the net rate of conversion of some ecosystems has begun to slow but in most cases this is only because little habitat remains for further conversion.
