The history of the country is destroyed Bad policy is implemented as a result Children’s educations are wrecked by feeding them intellectual garbage The economy is damaged by taxes and destructive policies to restrict CO2 Science itself is wrecked.

Amazing how a small handful of unscrupulous people can wreak so much havoc.
