You are all volunteers and your action counts!
Everybody is already a volunteer for a sustainable future. Every single person is acting for sustainable development, by helping friends and family, by recycling waste, by teaching the kids how to turn off the tap. Most people are already volunteering without being aware of it. Some people volunteer further, and get involved in development or environmental action for a day, for a week, for a year. Their work, big or small, might sometimes go unnoticed to the world. But their actions count in the communities that have benefited from their hard work.
