global problem

I think that David Keith may have valid solution to the problem. At least it appears this way, for emitting the particles into the atmosphere, may cause the heat to deflect off the particles and lower the effect of global warming. David seemed to be a very influential speaker. The fact is that nothing much is being done about this problem. People know about the topic however I don't believe they know how serious it is. Some may not even be worried because they will be dead and gone. I think that something needs to be done about the problem. David Keith presents a cheap but possibly effective way. He needs help from other people however, for he is almost alone, in researching solutions to the warming of the world. With more people, more research and more discoveries could be made , therefore leading to a solution if David Keith's proposal is not the answer.
