  1. (E) While deforestation threatens ecosystems across the globe, it’s
    particularly destructive to tropical rainforests. In terms of Earth’s
    biodiversity, rainforests are hugely important; though they cover only 7% of
    Earth, they house more than half of the world’s species. Through logging,
    mining, and farming, humans destroy approximately 2% of Earth’s
    rainforests every year, often damaging the soil so badly in the process that
    the forest has a difficult time recovering. In recent history, deforestation has
    led to approximately 36% of all extinctions, and as the habitat loss
    accelerates, that number is bound to increase.
