Science - Helium.

This blog is about Helium, and how it is beginning to be rare on earth.

I think that the reason that helium is so rare on earth, and very common in the universe, is because we are using so much of the helium on earth, that there just is not enough of it.

We need helium for many different things like for example testing rockets safely, or something even more important, like using medichal MRI machines. If we don't have anymore helium on earth, then things that have taken humans many years to figure out, we will soon either not be able to develop, or use at all.

We could start researching for alternatives, that we could use instead of helium in some cases. If we started using alternatives, for some of the things where we would usually use helium, then we'd be able to use less of our helium, and in that way, we could maybe have helium for longer than we thought. We would also already have alternatives, that we could use for some of the things that we would need to do, when helium is gone.

I think we could get stuck in the same situation with other elements too, espiacially with the elements that are most important to us, and that we use the most. We might get stuck in a really bad situation, if we ran out of something that we use even more than helium.
