Q: I am under the impression that monocropping and not specifically GMOmonocropping is responsible for agricultures threat to the environment. My impression is that land management practices such as beneficial insect attractors, crop biodiversity and...

A: Your question reflects a common view that “monocropping” and the use of agrichemicals damage the environment, and that alternative diversified cropping systems can reduce these threats. This is clearly an over simplification of the reality, as all agricultural production systems are complex and balance a number of trade-offs between economic productivity and environmental sustainability. Very few agricultural systems are true “monocrops,” except for perhaps at scale of individual fields,... Continue Reading

A: What a great question! It even caused me to put down my breakfast of coffee and mixed GMO and non-GMO grain cereal. Note in passing that, worldwide, coffee is being devastated by coffee rust disease: resistance has been discovered, but one way to protect our crops from disease in the future will be biotechnology. An example of this is GMO blight-resistant chestnut, where a gene from wheat destroys the plant-damaging toxic chemical produced by the fungus, so rendering the tree disease-resistant...

A: Earthworms, along with other soil macroorganisms, provide essential ecosystem services. In the most important book written on earthworms in the last 100 years, Edwards and Bohlen (Biology and Ecology of Earthworms, 1996) examined the potential impact of many agricultural products on earthworms. The authors rank the toxicity of active ingredients to earthworms using a scale of 0 (relatively nontoxic) to 3 (extremely toxic). Glyphosate, the active ingredient in Roundup formulations, is ranked 0... Continue Reading
Q: Would growing GMOs in a highly contained, enclosed environment be the ethical, scientific and responsible thing to do for the first 100 years or so, or do you consider this planet to be an open laboratory where you're entitled to do anything...

A: Humans have been manipulating their own environment and that of other species closely related to them for thousands of years. These changes have given rise to domesticated and human-dependent animal species, such as cows and sheep, as well as the many varieties of dogs and cats. In the same manner, most agricultural food crops are very different from their “wild” ancestors because of human intervention. Intervention in the domestication of food crops has given rise to higher-yield, less toxic... Continue Reading
Q: Has there been any cases where gmo crops have harmed bees or other wildlife where non gmo crops have not? Also are there any studies on the affects of gmos on bees or other important insects?

A: All plants genetically modified to be insect resistant or herbicide tolerant undergo a risk assessment, which includes evaluating potential adverse impacts on nontarget arthropods (insects and related animals). Major groups tested include pollinators (e.g., honey bees and bumble bees), predators (e.g., lady beetles and green lacewings) and parasites (e.g., Diaeretiella rapae, an aphid parasite). In addition, soil-dwelling animals, like earthworms, isopods, Collembola, nematodes and protozoa,... Continue Reading
