These agencies have definitely made their fair share of mistakes/coverups and have had plenty of corrupt staff, but the overall quality of our health, food, air, and water would be significantly worse without them. I hate cliches, but we can’t let perfect be the enemy of good. For the most part, the scientists and bureaucrats that work at these agencies do their best with the extremely limited resources we give them. Their best is not perfect, but it is SO much better than nothing.
