Has pesticides contributed to loss of biodiversity at all?

    Yes – there are links below that address this problem.  Insects, bird species, butterflies, bees, amphibians, plants and humans are affected by pesticides, as well as our air, water and soil.  Different animal and plant species perform vital functions in the environment and those areas with greater biodiversity tend to do much better.  The species that we are trying to eliminate with pesticides, will have some survivers and they may pose even worse problems as they will be immune to the current pesticide which then forces us to create something even stronger.

    A great historical example of pesticide direct effect on biodiversity was the population decrease of multiple species of birds in North America in the 1960s. DDT became a notorious symbol of detriment to biodiversity, causing nervous system shut down and the development of thin eggshells and low levels of reproductive hormones. Peregrine falcons, ospreys, bald and golden eagles, kestrels, and other predatory birds suffered localized disappearances and overall population decline.

    The Bald Eagle is a great animal example of how dangerous pesticides can be – they had some major issues with them in the 1960s. Scientists back then noticed that eagles were laying super thin eggs that cracked under their mothers’ weight. It turned out that DDT, a super-powerful pesticide, was the cause. DDT was banned in Canada in 1985 and the eagles have been making a comeback ever since.
