George Guimaraes is a vegan dietitian and animal rights activist in Brazil. As a dietitian, his practice is dedicated to the research of vegetarian diets and counseling of vegetarian patients through NUTRIVEG Consulting on Vegetarian Nutrition. He is also a regular lecturer at universities and events for the general public and contributes regularly as a writer. Guimaraes is also a dedicated activist, founder and president of VEDDAS (Ethical Vegetarianism, Animal Rights Defense and Society), the most active animal rights organization in Brazil. VEDDAS promotes vegan outreach through educational activities and multimedia weekly interventions on the streets and organizes protests and events on issues ranging from vivisection to animal farming and animal entertainment. Also organizes the National Animal Rights Gathering congregating hundreds of activists from Brazil and abroad on a single location for four days to immerse, share and learn with one another. While enjoying relative liberty in spreading the word on animal rights, VEDDAS is actively engaged in the campaign to stop the construction of the Belo Monte dam in the Amazon, a campaign that has led to the assassination of tens of activists in recent years and is facing all forms of government repression. George frequently speaks at animal rights events worldwide and was part of the crew aboard the Steve Irwin on the 2010-2011 Sea Shepherd Antarctic campaign.
