Why do African elephants need our help? African elephants, the largest terrestrial mammals on Earth, are found in 37 countries across Africa and their populations are decreasing at alarmingly high rates. The poaching and killing of elephants for their ivory tusks has caused some elephant populations in Africa to decline by more than 60%. But those aren’t the only threats elephants are facing, as human population continues to climb and land is converted for human use, their habitat is shrinking and becoming fragmented. This fragmentation is placing elephants along fringe areas where conflict with humans is much more likely.
