World Conservation Problems - The Future

Can the world's problems be overcome? Is there a future for humans on Earth? Will they be able to feed the expected 8 billion people by the beginning of the 21st Century? Is the human race heading for self destruction? These are difficult questions to answer with any certainty. We can only speculate. We do not know the real limits of population expansion which the world's resources can support. We are still assessing the role of all living organisms in our technological age. There is still much to be learned about nature and its potential for serving our needs in a sustainable way.
