The proof is obvious that one of the major reasons of the bees’ decline is by the ingestion of GMO proteins. This is problematic, as there is such an increase of indigestible foods in humans and bees. The situation of colon cancer in humans is somewhat similar in occurrence.
One part good news. But there are trials of GM wheat and potatoes that have been going since 2011 and are still continuing.
GMO crops are believed to be a major cause of disease among bees.
