In the previous section there has been a discussion of the sensitivity of CFT species and communities to changes in the natural environment. The environment may also be changed as a result of human activities - anthropogenic impact - and one of the concerns of management is to distinguish the two. There are two broad categories of human impact which can affect natural communities. One is the addition of substances to the environment, broadly classified as ‘pollution’. The other is human activity in the marine environment, such as fishing and diving. The two will be considered in turn. However, not all human activity is necessarily negative in its impact on CFTs - see section E.
