Remember that recent SpaceX rocket that exploded on the launchpad? That pollutes the area and could have been predicted by any actual expert.
It did not explode on the launchpad. It exploded 4 minutes into flight, at an altitude of 39 kilometers.
There was no "pollution" in the area. A bunch of pulverized concrete and sand got thrown around. They actually did expect the pad to be damaged by the launch, just not quite to that extent; they already knew they would need to rebuild it with a more robust design but figured it would survive one test launch so they delayed the planned renovations until after the launch.
Even if it had exploded on the launch pad, it would not have polluted the area, Starship is fuelled with liquid oxygen and liquid methane. Whatever didn't burn would have simply evaporated away.
If you're going to criticize Elon Musk or SpaceX you should use criticisms that are actually based on real facts, otherwise you end up hurting your position.
