This conclusion presents some closing thoughts of the concepts discussed in preceding chapters of this book. The book outlines a unifying theory, which is based on Hutchinson's concept of the ecological niche, which integrates genetic, molecular and physiological processes that are difficult to parametrise in classical approaches because of the large number of parameters that need to be estimated and issues associated with oversimplification and assumptions. The funding needed to monitor the marine environment is often dependent on private support gained as part of local studies on the impact of human activities. Monitoring should become global, and sharing of biological data is an absolute prerequisite to better understand how ecosystems and their biodiversity will respond to global environmental change. The book shows a large part of the arrangement of biodiversity and its responses to environmental and climate changes are quasi-deterministic, and can therefore be anticipated.
