5、生物多样性受到有史以来最为严重的威胁。 地球不属于人类，而人类属于地球!,生物经历过的5次自然大灭绝 奥陶纪-志留纪之交大灭绝 时间：4.39亿年前 原因：全球气候变化 后果：约有100个科的生物灭绝 晚泥盆纪弗拉斯期-法门期之交大灭绝 时间：3.67亿年前 原因：气候变冷，浅水中含氧量下降 后果：70%物种消失海洋中无脊椎动物损失惨重,二叠纪-三叠纪之交大灭绝 时间：2.5亿年前 原因：气候变化或天体撞击？ 后果：物种数减少90%以上 三叠纪-侏罗纪之交大灭绝 时间：2.08亿年前 原因：起因不详 后果：灭绝程度相对较小，恐龙崛起 白垩纪-第三纪之交大灭绝 时间：6500万年前 原因：小行星

6、或彗星坠落地球 后果：恐龙时代在此终结,Population explosion,1.1 billion people on the planet dont have access to safe, clean drinking water.
