After hearing about all the horrible things we have done to these creatures, you must feel pretty horrible (or not, but then if that's the case, then are you even human?). But if you are one of those that are NOT some sort of alien spawn with no heart, then this might make you feel better about yourself.
When I first heard the word 'Cobalt', my reaction was, "Huh? What is Cobalt?". I had no idea what I was doing to the environment either. Just under a year ago, if you asked me what cobalt was, I would shrug and keep talking about some sort of horse camp story. But enough about me. My point is, I didn't always save the world either. But now that you know what is going on, you don't have to wait for some school project. You can do it entirely on your own! Here are some things that you can do to help.
Just remember, that everything you do, is important. It can be hard to save the world. But with a little bit of effort, there would be a big difference.
