But not everyone has found a better life in the city, and homelessness has become a problem in many urban areas. Habitat for Humanity is one organization that helps make sure people in the cities have houses. So far, the group has helped build more than 300,000 homes for people in 59 countries. In some countries, many children do not have access to basic education. This means they do not even learn to read and write.
Basic education helps countries to develop economically, reducing poverty.
And countries where more people are educated tend to take better care of their environment, too. As you can see, we are facing many issues as our population reaches the 6-billion mark. Fortunately many organizations and citizens worldwide are working to solve these problems. The way you live makes an impact on our environment, and you can do your part to make the world safer for Child 6 Billion. Help keep the air clean by being smart about the energy you use.
