In modern times the introduction of the motor car has allowed populations to slowly spread outwards from existing urban ...

Covering about 70% of the earths surface, the oceans are a highly productive system which continuously recycles chemicals, nutrients and water through the “hydrological cycle”, which powers climate and weather, and which regulates global temperature by acting as a giant heat reservoir from the sun. About two-thirds of the world’s population live within 60 kilometres ...

Lakes are one of the planet’s most important freshwater resources providing water for domestic, agricultural and industrial uses for much of the world’s population. We are all familiar with the image of Earth as the “blue planet” when seen from space. It gives the impression that water is plentiful and indeed it is. However, pictures ...

Although it has often received bad publicity, many people argue that nuclear power has a significant part to play in maintaining a balanced energy policy.
