Explanation:
Detailed explanation-1: -5 ways in which humans are affecting biodiversity are: accidental introduction of alien species and thus native species displacement (local extinctions), habitat fragmentation and loss of genetic diversity (inbreeding problems), climate change (ocean acidification, atmospheric temperatures).
Detailed explanation-2: -The main driver of biodiversity loss remains humans’ use of land – primarily for food production. Human activity has already altered over 70 per cent of all ice-free land. When land is converted for agriculture, some animal and plant species may lose their habitat and face extinction.
