Understanding water quality
Water is arguably the most important physical resource as it is the one that is essential to human survival. Understanding the global water cycle and how we use water is essential to planning a sustainable source of water for the future. In the UK there are areas where water supplies are limited, shown by recent droughts. Globally, there are many areas that do not have enough water to support the current population adequately. Decisions will have to be made on the best way to use water in a worl

Aquatic mammals
Mammals come in a bewildering variety of shapes and sizes and yet all of the 4700 or so species have some characteristics in common, which justifies the inclusion of diverse types within a single group. Although mammals evolved on land, a number of species have become adapted to spending part or all of their lives in water and it is these mammals that you are going to concentrate on in this course. You will meet some aquatic mammals, find out how we can study them, consider their evolutionary hi

1.7 Summary

  1. Figure 12 summarises the ways in which the Earth's surface and atmosphere gain and lose energy. The main points are as follows:

    • A proportion (the planetary albedo) of the incoming shortwave radiation from the Sun is reflected (or scattered) directly back to space, mainly by clouds and the Earth's surface (especially snow and ice cover), but also by aerosols (e.g. dust, salt particles, etc.). Most of the rest is absor

1.3.1 The vertical 'structure' of the atmosphere

The atmosphere is not a simple, uniform slab of absorbing material. On the contrary, it gets progressively 'thinner' or less dense with increasing altitude (height above mean sea level); i.e. the total number of molecules in a given volume of air is lower, and so is the pressure. About 80% of the total mass of the atmosphere is within some 10 km of the surface; 99.9% lies below 50 km.

The important corollary is that the key greenhouse gas molecules (H2O and CO2

1.3.5 Corporate connections

As I mentioned in Section 2, what was happening in the factories of overseas contractors was said to have appeared remote to most, if not all, the chief executive officers of the clothing multinationals in the 1980s. Overseas contractors were selected on the basis of market price, quality and reliability, not on whether forced or child labour happened to be employed to stitch the product together. However, all that changed in the early 1990s when the geographical ties between the big retailer

1.3.4 Bringing remote sweatshops within reach continued

Another claim made by the movement is that we are all in some way connected to a market system which effectively allows sweatshops to exist in the first place. This is about more than targeting the big brand names and linking them directly to exploitation abroad; rather, it is about piecing together the global market machinery that ties the corporate buyer, the boardroom executive, the factory owner and the consumer into a system which establishes particular lines of responsibility (Ha

1.2.2 Offshore fragments of industry

The rise of global factories in the 1970s owed much to the rapid improvement in transport and communications technologies which took place at that time and which made it possible to keep in touch with, and control, production processes in different parts of the world. Just as significant was the fragmentation of industrial production whereby parts of the manufacturing process could be relocated over vast distances. Sewing in garment and footwear production, for instance, was among the

2.2 Economic valuation: towards ecological economics

The blue whale could have supplied indefinitely a sustainable yield of 6000 individuals a year.

This is one of the earliest references to sustainability in the literature, taken from the 1971 edition of the science journal Nature (cited in Senge et al., 2006, p. 45). Here, the blue whale is given instrumental value – a means of measuring not the survival of the blue whale for its intrinsic v

2.1 Accounting for the consequences of environmental harm

The ethical tradition of consequentialism informs not only what matters from the perspective of caring for the environment, but also what matters from the perspective of accountability towards it. In eighteenth-century Europe, the actual environmental consequences of rapid economic development, triggered by the industrial revolutions taking place at that time, prompted an increasing concern for accountability. The most evident expression of this came with ideas of sustainable development

1.2 The influence of narratives and spiritual traditions

In his 1974 publication Man’s Responsibility for Nature, John Passmore – an Australian philosopher who pioneered a concern for developing a change of attitude towards the environment – argues from an explicitly anthropocentric perspective. He suggests that the special ties between parents and children provide the basis for continual development of obligations amongst humans, which can then translate into a more responsible engagement with the environment.
