Veterinary science has an increasingly important role to play in addressing the global challenges of the 21st century, particularly in working towards worldwide disease control and food security. This contribution will be vital in the face of pressures resulting from a rapidly expanding, increasingly mobile human population and climate change. Globalization will, conversely, also see world affairs impacting upon veterinary practice globally as never before. The advances of the 21st century have led to a world that is extensively interconnected. People, information and resources move around the globe at unprecedented rates and with ever more complex interactions. Yet despite these advances today’s globalized world also faces unprecedented challenges, not least the pressures on the environment, health and livelihoods brought about by rapid population expansion and climate change. These factors have not gone unnoticed by the veterinary profession, which has recently begun to place increased importance upon its global role in animal, human and environmental health, and in sustainable development. Human health is intrinsically linked to that of animals and of the environment, and that many of the answers to the pressing health and welfare problems of the 21st century can be found through interdisciplinary collaboration between professionals working in a wide variety of fields. Contemplating the above facts, we believe that organizing veterinary conferences worldwide would be an expedient platform in addressing and overcoming the current issues.
