There is no correlation between asthma and fracking. There is not even a plausible mechanism for such a causal relationship. That is a very odd point to make.
The video mentions a variety of hydrocarbons emitted from fracking sites (and a noticeable smell), which would be a plausible cause, no? That said, I don't have a dog in this fight and no strong opinions, and happy to be educated with better facts.
