Just about the worst population control method appears to be vaccines. Here in the US people are literally being vaccinated to death as they are the world over. I don't know about this Attenborough fellow, but I am convinced that Bill Gates' support of vaccinations, GMOs and soy alternate "meat" is straight forward depopulation. Picture related. U.S. vaccine risk aware people and groups have forced the U.S. HHS Department to admit it has failed to address vaccine safety as the law passed in 1986 required them to do. Expensive US drugs like Otezla, Humira and Cosentyx treat conditions that are most probably due to vaccines. The wicked make money off of harming us!
