How is biodiversity threatened and how can we protect it?Land use

All organisms depend on other organisms and the environment to live. Human activities can result in ecosystems being damaged. Conserving biodiversity will make sure we have the resources we need.

Land use

The larger the human gets, the more land we require. More houses must be built, more resources found, more food must be grown and more waste is produced. This often means less space and fewer resources for other animals and plants.

Often is significantly reduced when land is cleared for human uses, such as building, quarrying, farming and waste disposal. Think about the reduction in biodiversity that occurs when an area of rainforest is cut down to grow crops.
