How Global Population Growth is Creating Serious Environmental Problems

Today's worldwide human population of 6.6 billion is expected to grow to more than 9 billion by 2050. And with each new person added to the total population, the competition for finite resources such as food and water increases, the lack of those resources in many parts of the world becomes more deadly, and problems such as global warming become more difficult to solve.

Knowing the changes required to achieve a sustainable balance between human population and available resources is easy, but finding a way to make those changes--and to make them stick--is one of the great environmental challenges of the 21st century. Find out more about population growth, its impact on the environment, and what can be done to create a better world.
