Would be interesting to analyze whatever rain you end up collecting down there. I do worry about you folks and hope you all (or like the rural folk say up here, "yous guys") are able to find ways to manage through this. It must be so horrible. Just imagining makes me cry and I can't express enough how much I feel for you.
Up here in Ontario, Canada, whenever strong storms hit the Gulf, they eventually make it up our way. The get a power boost when they hit the Great Lakes, and then head eastward along the north of the St. Lawrence Sea-way
Those of us forum members in Ontario, Quebec, and the maritimes will eventually be affected by the toxins as well. It doesn't take a rocket scientist (or theoretical physicist) to see how agriculture will soon be in peril from toxic rain, first in the US and then in Canada.
I was originally thinking I could grow my own veggies, but what would I water them with? I would need to get some heavy-duty purification/filtration systems going. As well, everything would have to be grown under plastic or glass, and planted in containers so the roots avoid the soon-to-be-contaminated water table.
But all that effort could be in vain if/when the hungry masses come and raid the garden.
Hmmm, I'm going to have to put more thought into how to protect and sustain my family while also providing help to others.
Might be time to get out of the city and move to the country, as it could take a couple of growing seasons before one can build up sufficient stockpiles of preserved food.
I was also thinking that, since oil holds heat longer than water, storms might pick up considerably more power than usual when they hit the oil-soaked Gulf.
I hate to think how intense the resulting storms could become. And that's before the consequences of a halted or even weakened loop current on global climate.
Easier sad than done, this anticipate-nothing,-prepare-for-the-worst-and-hope-for-the-best approach.
