5.5 Emergency planning as an organisational management function

If emergency services' EPOs plan to respond to other people's emergencies, people managing a business activity with major incident potential have a different perspective. They have to respond to emergencies within their own organisation. In effect, if an incident occurs, the organisation is itself in a crisis, with functionality impaired. All of this comes into the corporate governance area and the implications of internal control. This requires companies to ensure that they have a sound syst

4.2.1 Comparing the management systems

One approach to BS 8800 follows the ISO 14001 model, and the ISO 14001 system itself was closely modelled on the previous ISO 9000, with the 2000 revision of ISO 9000 following ISO 14001 principles. As a result, you may imagine that there are similarities between the standards. Many of the elements are similar, and some are nearly identical. Management systems share common elements, including developing and documenting procedures, training, record keeping, auditing, and corrective action. Fig

3.2 Multiple causes

Now we will explore multiple causes using an example familiar to us all – road accidents. The deaths of about 10 people each day on the UK's roads are less dramatic than, for example, the capsize of the Herald of Free Enterprise, but one feature that links them both is the element of risk associated with everything we do – and even with inaction.

We have just seen that many factors contribute to the risks which result from the inherent hazards associated with something we do.

8 Summary

  • We are biologically predisposed to provide for our offspring and may try to ensure that this provision continues after our death. However, our interactions with other members of society are wide-ranging and many people leave legacies to benefit the wider community.

  • All species alter their environment to some extent because they do not live in isolation from one another. The study of the interactions between plants, animals and their environ

6 Population growth

Earlier it was stated that three factors check population growth. These are predation, disease and insufficient food supply. For much of our history, our ancestors’ numbers were indeed limited by wars, disease and famine. The world population remained relatively stable until around 300 years ago. Then at the beginning of the 19th century (100 years after population growth started its geometric increase), the demographer Thomas Malthus predicted that population growth would outstrip food pro

5.4 The ozone hole

Another group of greenhouse gases, the chlorofluorocarbons (CFCs), are double villains because they are also implicated in the destruction of the ozone in the upper atmosphere. CFCs are synthetic gases used in aerosols, as solvents and as coolants in refrigerators. They are also used to make a light insulating material called Styrofoam, from which packaging for hot take-away food containers can be constructed. It has been relatively easy to get international cooperation to ban further product

5.3 Global warming

Media attention has been such that it would be hard to have missed the fact that global warming is considered to be a ‘bad thing’. Why should this be so? What is so wrong with being a bit warmer? Anyway, is global warming really occurring and, if it is, what are the causal factors responsible for it?

Let us deal with this last question first. As we sit on a beach in summer, or in a sunny window seat in winter, we are aware of the Earth being warmed by the Sun. In fact the Earth is w

5.1 Pollution and loss of biodiversity

Unfortunately, halting the disappearance of species cannot be achieved simply by measures such as putting fences around special habitats and asking people not to pick the flowers or disturb the breeding birds. Many species are vanishing because of pollution. You probably have a good understanding of the meaning of this term, but it is variously defined. The Open University has a course on environmental control and public health, in which pollution is defined as the introduction into th

4.1 Human predation and extinctions

There are a number of ways in which humans have altered ecosystems, that have led to the decline of particular species. We will leave to one side any major interference such as felling forests to provide land for agricultural and urban development, and instead begin by looking at examples where we have eroded or eradicated stocks of particular species. This has notably been a consequence of the over-exploitation of food species (prey items). Predators do not normally eliminate their prey (see

3 3 Present energy sources and sustainability

What are the principal energy sources at present, and how sustainable are they?

About 80 per cent of the world's energy is currently supplied by fossil fuels such as coal, oil and gas. Present estimates suggest that, at current consumption rates, there are over 200-years' worth of coal left, 60-years' of gas, and 40-years' of oil. Fossil fuels are hydrocarbons, and their combustion releases carbon dioxide into the atmosphere, one of the main causes of the human-induced

6.4 Technology and environment

At the start of this unit I asked a simple question: am I damaging the environment by using my fridge? I warned that it wasn't my intention to give a simple answer that we should all stop using refrigerators or all carry on regardless. Instead, we have explored the issue more widely, calling on a range of ideas and background information in the Case Studies. It is time to review some of the concepts we have been using.

5.4 Discussion

We seem to have travelled a long way from the Industrial Revolution in Europe, but many of the impacts on New Zealand's ecosystems described here can be traced, in part at least, to reverberations from these developments.

What lessons can be drawn from this example? Perhaps I should start by emphasising this is not meant to be a complete account of the environmental history of New Zealand. For example, I have not discussed any responses from the population once they realised that harm w

5.1 Food preservation and the development of refrigeration

Most societies have had traditional methods of preserving food: drying, baking, pickling, salting, smoking, the use of sugar, and in cold climates, freezing or chilling, with the use of ice houses in the summer. These techniques were usually carried out at a local level, which meant that most perishable food was consumed near to where it was produced, and any food processing was usually small-scale and localised. Cattle and livestock, for example, were moved ‘on the hoof’ from their pastu

4.4 Discussion

In this second case study, I have described two different trends in energy use by cold appliances over the last few decades. On the one hand the efficiency with which appliances use electrical energy has improved but, in spite of this, their consumption of electricity has increased significantly in recent decades. Since 2000 consumption has started to decline, probably as a result of the introduction of minimum energy standards. The trend will only continue if we demand and use the most energ
