With the struggle to adapt comes the struggle to make CA grow across the globe. CA has not spread as quickly as most conservationists would like. The reason for this is because there is not enough pressure for producers in places such as North America to change their way of living to a more conservationist outlook. But in the tropics there is more pressure to change to conservation areas because of the limited resources that are available. Places like Europe have also started to catch onto the ideas and principles of CA, but still nothing much is being done to change due to there being a minimal amount of pressure for people to change their ways of living (FAO 2006).
