Our Priorities for Saving the World:
Yet another great TED video. Bjorn Lomborg takes a very interesting approach to improving our world. There are many, many very large problems that our world faces today; However we cannot help everyone with everything and must prioritize and focus on the problems where we can make the biggest difference. He and his team look at the big problems we face today in our current environment and prioritize them into categories (bad ideas, fair ideas, good ideas, and great ideas)to establish which ones we should avoid for now and which ones we should try to act on immediately. Starting at minute 6:30 Bjorn Lomborg lists these categories starting with the bad ideas. While all the problems that are brought are still very big ones, there is issues about how much costs must be made to get what benefits. With bad ideas it costs a very large amount of investments to get very little benefit. Great ideas on the other hand have incur huge benefits from very little costs. At minute 10:20 Bjorn mentions the number one priority we should focus on, Aids, $27billion will prevent 27 million new cases over the next few years. It is apparent that disease and malnutrition are our top priorities while climate change is at the bottom of the list in our current environment.
