4.4 Genetic diversity and mass extinctions It is for this reason that there are now international agreements on the need to work together to retain genetic diversity in all species and, more generally, biological diversity (species and habitat diversity). From a Introduction This unit is from our archive and it is an adapted extract from Human biology and health (SK220), which is no longer in presentation. If you wish to study formally at The Open University, you may wish to explore the courses we offer in this curriculum area. To be able to understand the importance of the environment for our health, we need to know a little about the interdepende Acknowledgements The material acknowledged below is Proprietary, used under licence and not subject to Creative Commons licensing (see terms and conditions).

One such model was developed in the 1950s and 1960s by Abraham Maslow. Although it exists in many variants it is generally known as Maslow's hierarchy of human needs. In the most common interpretations it places the fundamental material needs of survival, such as food, shelter and safety at the base of a triangle, rising through social needs of belonging in human society, to 4.6 Global climate change continued
Record global temperatures
The global mean surface temperature of our planet has been rising steadily for 30 years. According to climate scientists, who have constructed a reliable global temperature series from 1860, nine of the ten warmest 2.4 Changing environmental attitudes So, from the start of the Industrial Revolution, people have been aware that the development of an industrial economy brings problems as well as benefits. But the benefits, in terms of productive capability, mobility, convenience, cheap consumer goods, and profits, were usually felt to outweigh the disadvantages, particularly by those in positions of power. Many of the accompanying negative factors, such as poverty and unemployment, or the creation of more destructive machines of war, if they 2.1 Environment and technology A central concern of environmental studies is the relationship between technology and our environment: how people use technology to transform materials into forms which can meet our needs and wants. In the process of doing this we inevitably change the environment which provides these materials but which also supports all life. A few moments ago I went to my fridge and took some milk out to add to a cup of coffee. I used this common example of a modern domestic appliance without a secon 1 Introductory advice There are two ways to approach this Introduction. The first is the more natural one: to read it straight through to get a general feel for its style and content, and to see whether you are going to find the unit and the issues it raises interesting; in short, to get an overview. There is nothing wrong with this at all. You will find as you read through it, though, that the Introduction covers a wide range of topics. In part this is because the unit authors takes a broad vi 8 Further reading For a wide-ranging, accessible and powerful defence of the idea of universal human rights and their role in the international system, see Chapters 1, 5, 6 and 7 of Beetham, D. (1999) Democracy and Human Rights, Cambridge, Polity Press. For a brilliant feminist discussion of the claims of culture and the claims of universal rights, set in a context of a range of concrete, contemporary examples, see Benhabib, S. (2002) The Claims of Culture: Equality and Diversity in the Global 6.1 Introduction The international level can be viewed as an arena of politics in its own right and not just as a context for states and other actors. If we think of the international world in this way, how should relations between states, and other actors on the international stage, be constructed? To what extent should those relations be regulated? We can ask whether relations between states, and states' policy making, should be dictated by allegedly universally shared human rights principles, or by other o 5.2 Human rights in the international arena The UN's 1948 Universal Declaration of Human Rights asserted that the ‘recognition of the inherent dignity and of the equal and inalienable rights of all members of the human family is the foundation of freedom, justice and peace in the world’. It further affirmed that human rights should be protected by the rule of law, that they were ‘essential to promote the development of friendly relations between nations’, that these fundamental human rights include the equal rights between men 4.1 Distributive and commutative justice Justice is commonly thought to have two applications which Aristotle distinguished as ‘distributive’ and ‘commutative’ justice. The first, distributive justice, is concerned with the distributions of things (rights, goods, services and so on) among a class of individuals. 2.2 The origins of a rights discourse In some form, the ideas of ‘rights’ and ‘justice’ could probably be found in all societies and cultures. They are moral concepts because they are concerned with moral ideals; with how things should be rather than describing how things are. However, the notion of rights now has a prominence in political debate in a way it has not had in other times and places. In the political thought of the ancient world, for example, a key question was how individuals could best contrib 1 International human rights: an introduction There are many examples of claims for rights in the international sphere. One example was reported in September 2002. The British government was asked to make efforts to have a British man held by the Americans at Guantanamo Bay deported to Britain to face charges of terrorism there in connection with the attacks on 11 September 2001. Concerns were expressed about the denial of this man's human rights at Guantanamo Bay. Are alleged terrorists entitled to human rights? Can the denial of 2.2 Climate change in a globalised world As you will recall from Reading 1A, the people of Tuvalu are now arguing that larger and more affluent nations should take responsibility for the climatic changes threatening their country. As Paani Laupepa from the Tuvalu environment ministry put it: ‘We are on the front line … through no fault of our own. The industrialised countries caused the problem, but we are suffering the consequences’ (Lynas, 2003). Before we look more closely at this charge, and the scientific evidence that is 1 Dividing the planet A good globe can set you back quite a lot of money. Of course, I don't mean the little moulded plastic planets or the globes you can blow up as if the world were a beach ball, but the decent sized ones that sit solidly on turned wooden bases and quietly emanate authority from the corner of a room. Yet these days, it hardly seems worthwhile making such an investment. Countries appear to change their colour, their shape or their name with remarkable rapidity.

This means that the people who most need a share in global prosperity are still those least likely to obtain it.

This section of the unit will help you to think about how you can turn the very familiar, but usually passive, process of watching a video into the active process of learning. Watching the video will involve the skills of engaging with the material and making sense of it for yourself, just as if it were written materials. The advantage o 1.6 Defining global markets Global markets for manufactured goods, as opposed to, say, primary commodities such as oil and timber, arose largely in the second half of the twentieth century as trade between countries intensified. The lowering of transport costs and the relative fall in trade barriers enabled firms in one country to compete wit
