It's an information problem because we base much of our behavior on feedback loops. When we get a big electricity bill, we take a closer look and perhaps rely less on our heaters or air-conditioner. When we see the odometer on our car hitting big numbers too soon (and repair bills looming), perhaps we look into a job closer to home. There's thousands of examples, many of which have an impact our our environment.
So if we focused on developing a tool whose sole purpose was to give us quantified feedback on the consequences of our actions - much like how we use utility bills - we might be able to make a real dent in the big problem of climate change and others like it. We already have the pieces for a tool like this (Internet, computers everywhere, software libraries) along with the skills of technologists, so what's needed is the vision and the demand.
