Except that you blame contrails as a source of pollution and poison, while ignoring cars, industry, common chemical use in small and large applications at ground level. These surface sources exceed anything the planes could "dump" by orders of magnitude.

There's a helluva lot of folks living on this planet, and the industrialized portion creates a lot of byproducts in sustaining their lifestyle...I feel these are the pollution sources you should be concerned about, not some yet unproven chemtrail business.

Again, where is some real data showing the actual makeup of these "chemtrails"...this is a large black hole of missing information that can't be addressed with "it looks like...". Someone needs to get up there and gather some material in a scientific fashion.
