my worst fear is that all of the pollution that we make will continue and all of the trees will die, which will lead to no oxygen, and no more life on earth eventually. I also fear needles.... I had to get a tetanis shot a few weeks ago and I almost punched the lady in the face when she reached for the needle... she stepped back and had a really surprised look on her face and my mom, who was sitting next to me, had the same look..
