A 3D Map of the Whole World Before Climate Change Ruins It

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.

What are your thoughts on this one?
