In other words, Nye says that GMOs could be potentially dangerous, because the effects of GMOs on our planet are difficult to pin down since the variables in our environment are constantly changing. Emily Glass, author of “The Environmental Impact of GMOs,” presents one of the main problems with genetically modified agriculture. Glass writes that “GMOs can be toxic to non-target organisms” like bees and butterflies. The American Museum of Natural History reports that bees have suffered a "rapid and recent population collapse" and Katie Valentine also reveals that the monarch butterfly population has "declined by 90% over the past two decades" due to loss of plant biodiversity. as well as pesticides that harm pollinating insects. Since Monsanto created its seeds in the laboratory, biodiversity has been lost because all crops are identical copies created in mass production. This style of monoculture farming makes it more difficult for bees and butterflies and even some species of pollinating birds, like hummingbirds, to pollinate. Modern agriculture affects all living things, including humans, because "irrigation used to grow genetically modified foods naturally carries all of these problems into water sources and into the water.
