This non-profit alliance of more than 200,000 citizens and scientists uses scientific evidence to lobby governments, corporations and consumers to act responsibly for the benefit of society. They often commission their own research into topics such as global warming or GM crops. Their interest in antibiotic resistance focuses on reducing the use of antibiotics in food animals. They advocate better treatment of animals — by using grass-fed systems, for example — to lower the need for drugs. The union encourages the public to get involved by writing to political representatives and signing petitions. The website also has a news section and links to related networks.
