Human exploitation of other mammals has passed through three histori cal phases, distinct in their ecological significance though overlapping in time. Initially, Homo sapiens was a predator, particularly of herbivores but also of fur-bearing predators. From about 11 000 years ago, goats and sheep were domesticated in the Middle East, rapidly replacing gazelles and other game as the principal source of meat. The principal crops, including wheat and barley, were taken into agriculture at about the same time, and the resulting Neolithic farming culture spread slowly from there over the subsequent 10 500 years. In a few places such as Mexico, Peru and China, this Middle Eastern culture met and merged with agricultural traditions that had made a similar but independent transition. These agricultural traditions provided the essential support for the industrial revolution, and for a third phase of industrial exploita tion of mammals. In this chapter, these themes are drawn out and their ecological signifi cance is investigated. Some of the impacts of humans on other mammals require consideration on a world-wide basis, but the chapter concen trates, parochially, on Great Britain. What have been the ecological consequences of our exploitation of other mammals? 2. 2 HISTORICAL PHASES OF EXPLOITATION 2. 2. 1 Predatory man Our nearest relatives - chimpanzees, orang utans and gorillas - are essentially forest species, deriving most of their diet from the fruits of forest trees and the shoots and leaves of plants.

Our relationships with marine mammals are complex. We have used them as resources, and in some places this remains the case; viewed them as competitors and culled them (again ongoing in some localities); been so captivated and intrigued by them that we have taken them into captivity for our entertainment; and developed a lucrative eco-tourism activity focused on them in many nations. When we first envisaged this special topic, we had two overarching aims: Firstly, we hoped to generate critical evaluation of some of our relationships with these animals. Secondly, we hoped to attract knowledgeable commentators and experts who might not traditionally publish in the peer-reviewed literature. We were also asking ourselves a question about what responsibility mankind might have to marine mammals, on our rapidly changing planet? The answer to the question; can, or should, humans have responsibility for the lives of marine mammals when they are affected by our activities? - is, in our opinion, ‘yes’ – and the logical progression from this question is to direct research and effort to understand and optimise the actions, reactions and responses that mankind may be able to take. We hope that the papers in this special issue bring some illumination to a small selection of topics under this much wider topic area, and prove to be informative and stimulating.
