Shorting a stock can be fairly risky, and if you're not familiar with it then don't do it.
However, if you are willing to risk some money and think a stock will go down within a certain time frame, then you could buy a put. Owning a put will allow you to get some of the gains from the stock falling for a fixed price. The risk is defined because you can't lose more than you buy the put for. So if the stock price goes up, you will have a defined loss.
The other wrinkle with puts (or calls) is that they expire (which a short stock does not). So you need to be aware of how the price will change with time as well. It is worth doing some reading on this subject. Getting the basic idea isn't too hard, but it is necessary before you make a purchase.
Yeah, and stop having sex and listening to rock and role.
That's a solution that just isn't going to work. We as a society need to plan for using more and more energy. Therefore, we need to create cleaner and cleaner ways to generate that energy. If solar can be implemented until we scale up fission, that's great. We can then rely on fission for a few hundred years until we get to fusion.
People will complain about the dangers of fission only while they ignore the dangers of fossil fuels and aren't required to use them. As soon as fossil fuels start running out, then fission isn't going to sound so bad. Frankly, it shouldn't sound bad now.
