Environmental Biology BSc

The unifying theme of this module is biogeochemical cycling - the production, distribution and cycling of materials on the Earth and their availability to, and use by, biological organisms. The module starts by covering the history of the universe, from the big bang to the evolution of the Earth's surface environment. Then you will explore the major global systems and their circulations as they are today - solids, liquids and gases. In the final section you will examine the major materials - including carbon, nitrogen, sulphur, oxygen and metals - and their budgets and cycles; and the interactions between biological and physical/chemical processes on a global scale. You will have a two-hour lecture once a week for this module. 

Starting with Darwin’s theory of evolution, you will learn how natural selection and other evolutionary forces have shaped the ways in which organisms interact with each other and their environment. In addition to lectures, practical classes will give you hands-on experience with a range of ecological and behavioural concepts in the laboratory and the field.

This module introduces you to the role and limitations of environmental science within the context practical environmental decision-making. During this module, we will look at how the degradation of our natural environment is creating unprecedented challenges for humans and society around the world. Science has a key role to play in helping us to understand and protect our environment. Public opinion of environmental issues and science is key to this, not least because the public funds 80% of scientific research. In this module, we will look at issues around scientific ethics, trust in science, denial, scepticism and science communication. Environmental problems are now very much part of the political agenda. We will look at the history of the environmental movement, environmental activism and environmental ethics. We will explore how and why we try to protect the environment through policy, legislation, international agreements and economic strategies.
