When the Gust Passes

It is kinda hard to imagine a nuclear bomb going off halfway around the world. What it would feel like over here. I think nuclear testing is bad to do on earth in the places they test at. I just wonder about water table problems when they do it underground. The water tables connect way underground where there is an ocean underneath the surface where we receive all the water. We don't want these deep wells tampered with underwater. I think nuclear testing should be done deep in space, where we can build prevention methods for larger cataclysmic asteroids they have the capability of hurting the earth. It may cost more but blowing that stuff on earth is dangerous to the environment as a whole.
