4.7 Summary

Human activity has been responsible for some extinctions and othe deleterious changes to habitats. These changes have not always been the result of thoughtless or selfish behaviour; often intentions were worthy, but outcomes were not as predicted. The importance of genetic diversith is demonstrated here in relation to Dutch Elm disease. The need to retain genetic diversity in plants, used for food and medicine, is recognized in such initiatives as the Kew Milennium Seed Bank Appeal.
