But what's good is that the technology we've developed and we're working with in South Africa, for example, is allowing us to map every single tree in the savanna, and then through repeat flights we're able to see which trees are being pushed over by elephants, in the red as you see on the screen, and how much that's happening in different types of landscapes in the savanna.
值得欣慰的是我们开发的那些用在南非的技术 比如 可以使得我们对热带草原上的每一棵树进行成像 通过反反复复的飞行 我们能够 通过屏幕上的红色标识 看到那些被大象推倒了的树 以及这些在草原上的不同风景区发生到什么程度
