And when those days get particularly hot, water is also lost on a massive scale. New research shows elephants can lose as much as 10% of their total body water (that’s almost as much as two full bathtubs) a day when temperatures soar. It’s nothing to worry about so long as lost stores can be quickly replenished … but in a world that’s rapidly warming and on a continent increasingly plagued by drought, life-giving water holes and water-rich plants are becoming ever more scarce. For an iconic giant with water needs to match, this spells trouble ahead. #elephants #endangeredspecies #climatechange #waterislife」12月28日 16時39分
