Climate%20change%20%u2018is%20the%20most%20important%20problem%2C%u2019%20former%20Reddit%20CEO%20says: YISHAN WONG: Well, trees are simple, reliable, cheap, and well understood. And so if there's one thing I learned in Silicon Valley when you want to solve very, very large problems, most of the complexity is actually in the scaling. And so in order to accomplish that, you want your unit solution to be as simple as possible. Every solution that's been proposed for climate change has to be done at enormous planetary scale.
