Why follow animal advocacy groups on social media? Social media is becoming (and in the minds of many, already has become) the fastest and easiest way to transmit up-to-date news and information. Following animal rights and advocacy groups on twitter or facebook will keep you informed of daily trends and topics that could affect your practice as it relates to animal law. Though these groups have very clear agendas, most do legal work relating to animals and frequently render updates and opinions on the most recent animal law events. As time goes on, the savvy lawyer will become accustomed to social media use and the ability to use it to stay informed on the topics that affect his or her practice.
