自1970起短短40年，野生動物的數量竟下降了52%，當中最嚴重的是淡水動物，而人類的數量卻增加了一倍。因為砍林、地球暖化、過分捕魚及捕獵等人為因素，有團體批評野生動物的消失是人類所害。依現時地球能提供的資料已超過人類的需求，我們必須要改變現時的消費及生活模式，減少浪費，不能讓情況持續惡化。
since 1970, the number of wild animals has dropped 52%. while 76% of freshwater wildlife have disappeared, human population has doubled. deforestation, global warming, overfishing and hunting, are samples of human destroying our planet and causing wildlife to disappear. humans are consuming more resources than the planet could sustain, and we must change the way we are living and consuming; create less waste and don’t let the situation get worse.
