Sustainable development is one of the buzz words of the new century. Almost everything we do nowadays we have to think about sustainable development. It is incredibly important. It’s a concept at the heart of the Earth’s survival. It’s not rocket science. There are so many people on Earth and so many resources. If there are too many people, there won’t be enough resources to sustain us – to provide us with food, water, shelter and other basics. Experts are trying to figure out how we can develop and sustain the human population. This is tricky. Anyone can see this is difficult. How can there be enough water, farmland, trees and raw materials for us to maintain our luxury lives? We can’t.
