If 1970 is our baseline, the world is on track to lose an estimated two-thirds of its wild animal populations by 2020.而且并没有停止。如果1970年是我们的基线,到2020年世界将失去估计三分之二的野生动物。But the extinction rate shouldnt be a surprise. Well-known species like eastern and western Gorillas are both critically endangered. Poaching is decimating elephant populations. And you can count the number of northern white rhinos on one hand.但灭绝率不该是什么意外。众所周知的物种,如东部和西部的大猩猩都极度濒危。偷猎正在减少大象的数量。你可以用一只手数清北方白犀牛的数量。The declines are caused by habitat loss from urban development, over-hunting, pollution, disease and climate change,all of which are tied to humans.数量下降是由于城市发展带来的栖息地丧失、过度狩猎、污染、疾病以及气候变化,所有这些都与人类联系在一起。The point is this: Earth is becoming inhospitable,both to animals and to humans. The plus side? Were getting better at recognizing our negative contributions, and researchers say thats one of the ;first steps; to fixing the problem.关键的一点是:地球正变得不适合居住,对动物和人类都一样。另一方面,我们正更好的认识我们负面的影响,研究人员称,这是解决问题的“第一步”。译文属。201611/476168In fact, you know what?事实上 你知道吗The remains of this paraglider and a bit of breeze that there is out in the lake,降落伞剩下的部分 加上湖面上的徐徐微风theres no reason why I shouldnt make something much cooler to cross this with.我可以弄出点辅助工具 让横渡行动变得轻松些Yeah, lets get this going.Im gonna try to make a kite.说干就干 我要做个大风筝First job is to modify the shape of the chute and attach the control lines.首先要调整一下降落伞的形状 再接上控制方向的丝线Leaves stuffed into each corner create a solid point to secure them.在伞盖的各个角落塞点小东西 用来固定它At the end of this, just put a clove hitch in it one turn, two turns and then in front of themselves.在这头打一个双套结 绕一圈 两圈 然后把它套进去The good thing about this is itll tighten on itself,and that then cant come undone.这种结绳法的优点在于它的两圈之间 可以相互压紧 而不会松开The lines are in place,next I fashion a makeshift control bar to help maneuver the kite.搞定绳子以后接下来要做个简易船舵 用以控制风筝的方向With the kite positioned downwind just off the shoreline,its time to get it airborne.把它安置在顺风方向的海岸线上以后 就是时候乘风而行了Lets see if we can try and get this thing launched from the water.看看能不能让风筝从湖面上飞起The wind is out, and the lines are tight.Give it a good pull.起风的时候 适时拉紧绳子 拉一把试试But the first two attempt dont work,on my third try, it catched just right.前两次尝试都没有成功 第三次它终于迎风而上Success.There we go.Up it goes.成了 好了 扶摇直上啊201608/459256TED演讲集 那些匪夷所思的新奇思想201611/478377
