BIOLOGY - Environment - Sustainable development
Like all living organisms, humans need resources to live. We need food, clean water and a shelter to live in. A few thousand years ago, this is all we would have wanted - a full stomach and a warm, dry home. But, as the human race has...

BIOLOGY - Environment - What is organic farming
As populations have grown, farming practices have become more intensified to maximise crop yields and ensure we can feed the ever growing population. Fertilisers and pesticides are used on crops, and animals may be kept inside in more...

BIOLOGY - Evolution - Mutations and Natural Selection
The way we grow and develop in the womb is controlled by our DNA. Small sections of DNA, called genes, carry the code telling the body how to build itself. Usually this works fine, but sometimes those genes carry mistakes in their code....

The Pros and Cons of Organic Farming
Organic farming isn’t all good. The yields are lower because more produce is damaged by pests, and carefully selected chemical pesticides cannot be used. With an ever-growing world population, we have limited land to feed everyone from....
