The Earth is changing rapidly, faster than anyone could comprehend. As the days pass by, more forests are burned, and more glaciers melt. As a result, the evidence of the world’s ancient cultures disappear quickly.
Change of some kind is, of course, inevitable — but it is happening more quickly and more severely because of the effects of human-caused climate change. And that has some scientists worried: The quicker Earth changes,the less time there is to learn from its past and understand its mysteries.
In hopes to preserve a record of our planet in its present state, two researchers proposed that lasers be used to create a high-resolution, 3D map of the entire world. In other words, we would need a lot of lasers.
