This is a guest post from Matt Link, Vice President of MapHook, a location-based social networking app dedicated to helping users explore their surroundings For the past few years, MapHook has partnered with the World Wildlife Fund (WWF) on several social-good initiatives through the use of “geo-activism.” The opportunity to use our mapping app to bring about legitimate change –in this case helping to reduce the amount of harsh and often dangerous activities that can hurt animals or destroy their natural habitats –is something that MapHook is passionate about; we know our efforts have great potential to have a valuable impact. Together, MapHook and WWF created two crowd sourced maps to help bring attention to the thousands of people around the world advocating for two very specific causes – the destruction of the Sumatran tiger’s habitat and the threat that certain fishing methods posed to the survival of the vaquita porpoise. Both campaigns are great examples of the power of “geo-activism” and something we will continue to do in the near future.
