A recent paper suggests all of the worlds' big animals will be extinct within 80 years. The study is part of a new initiative focused on New Zealand fauna, but global conservation also on their agenda.
The paper, published July 27, says that our non-human megafauna (large animals) are at risk of complete extinction by 2100.
The threat is particularly dire in sub-Saharan Africa and Southeast Asia, where much of the world's biodiversity resides.
Associate professor of conservation biology Jacqueline Beggs joined Paul Henry to explain.
