At the same time that DDT was hailed as part of the "environment of tomorrow", worries ended up expressed about its probable to get rid of harmless and effective insects (specifically pollinators), birds, fish, and at some point human beings. The difficulty of toxicity was intricate, partly for the reason that DDT's consequences different from species to species, and partly simply because consecutive exposures could accumulate, leading to destruction corresponding to huge doses.
