The soil half-life of glyphosate is approximately 47 days (with a range of 2 to nearly 200 days depending on soil type and various environmental conditions). But it is not active for a vast majority of that time. In order for glyphosate to be active as a herbicide, it must first (obviously) enter the plant. But glyphosate binds very tightly to soil particles almost immediately upon reaching the soil, and pesticides are not absorbed by plants while they are bound to the soil. Glyphosate is degraded relatively quickly by soil microorganisms, so there is almost never enough available glyphosate in the soil to cause plant injury. So although glyphosate can be detected in the soil for quite some time after application, it has no practical soil activity as a herbicide. We can spray glyphosate to control emerged weeds and plant a new crop on the very same day in most cases without risk of injuring the crop.

Could the decline of bees possibly be from all the hummingbird feeders that people have in their yards? I dont know about everyone else but my hummingbird feeders are always full of dead bees.

Hummingbird feeders often contain a sugar solution that is similar to plant nectar. Therefore, bees are attracted to these Hummingbird feeders, because similar to hummingbirds, the sugar/nectar attracts them. There are some hummingbird feeders on the market that are designed to prevent bees, ants, and other insects from getting in. Bee decline is complex and often misunderstood by the public.

If no proof has been found that GMOs are harmful to humans, then why are they banned in some countries?

GMO crops are not "banned" in any countries around the world in the normal sense of that word. Usually when something is banned for consumption, etc., it is because some problem emerged that needed a response. The history of regulation for biotech crops is quite different in that there were regulatory approval processes developed long before any such crops were commercialized. The goal was to try to anticipate any potential health or environmental issues and to make... Read More
Do GMOs cross pollinate with non GMO selective breed crop hybrids ? How can we prevent transgenes from entering the gene pool of non GMO crops or wild varieties if GMOs can breed with non GMO varieties?

A species is defined by the ability to reproduce viable offspring, so any two plants within a species generally have the potential to cross pollinate. Like any good successful mating, it requires the union of male and female contributions at the right time, same place. So absolutely, GE crops have the potential to cross with non-GE crops of the same species—if they manage to get it on through time and space. So the rules that apply to dogs and teenagers also apply to... Read More
