Today marks the 40th anniversary of Earth Day. Around the world, countries are renewing the call to protect and preserve the environment. The first Earth Day in the United States took place on April 22nd, 1970. It was initiated by Senator Gaylord Nelson and its events attracted nearly 20 million people who took part in demonstrations to demand the government take action in order to combat pollution. And while the world has certainly come a long way in addressing environmental issues, there is still much more to be done in local communities as well as globally.
World Health Day took place the week of 7 - 11 of April 2010. In the past, World Health Day has focused on issues such as the health workforce crisis, international health security, climate change, and resiliency and safety of health facilities and workers during emergencies. This year's World Health Day focuses on urbanization and health. The campaign organized events surrounding the theme "1000 cities - 1000 lives", calling on cities to open up their streets for health actitivities.
