12.102 Environmental Earth Science (MIT)
The geologic record demonstrates that our environment has changed over a variety of time scales from seconds to billions of years. This course explores the many ways in which geologic processes control and modify the Earth's environment and serves as an introduction to Environmental Earth Science Field Course (12.120), which addresses field applications of these principles in the American Southwest.

1.4 Caring for the consequences

The Light reading is an extract from the first part of a longer paper in which he goes on to argue for a more pragmatic approach from environmental ethicists to complement their important work on theorising over intrinsic value. Here you need register only the concern expressed by Light that ethicists should focus more on the immediate consequences of their endeavours in terms of being able to shape policy and action.

In thinking about such effects, Light might be regarded as following

6.6.2 Hibernation-induction trigger

Researchers have devoted much effort to the search for a possible blood-borne chemical messenger that might communicate a signal within the brain and to other body tissues, causing entry to hibernation. Serum from hibernating animals such as the woodchuck (Marmota monax; Figure 8), when injected into active animals, can induce torpor. Partly purified serum extracts are also able to induce hibernation-like behavioural changes in a variety of mammalian species. Chemical analysis of the s

7.1 The ascending auditory pathway

Up till now we have dealt with the anatomy of the auditory periphery and how the basic attributes of sound are coded within the auditory periphery. A great deal of additional processing takes place in the neural centres that lie in the auditory brainstem and cerebral cortex. Because localisation and other binaural perceptions depend on the interaction of information arriving at the two ears, we need to study the central auditory centres, since auditory nerves from the two cochleae interact on

2.5 Obesity and ageing

So, it seems that a part of the explanation for Ron's obesity, and the health problems that have led him to seek medical advice, may relate to the environment in which he is living, and more specifically the diet that he has chosen. It may also be a diet that is especially effective in activating the reward circuits in Ron's brain. However, Ron is also in his later middle age. A longitudinal study of people of this age in the USA suggests that average body weight increases by 1–2 kg per dec

1.4 Obesity

At the time of writing (2004) 20% of the adult population of the UK is classified as obese. The number of obese children has doubled since 1982, 10% of six year olds and 17% of fifteen year olds are now classified as obese. As shown in Table 4, obesity is recognized when the BMI exceeds 30 and occurs quite simply when energ

Are refugees fleeing persecution today generally seen as people who need help, or problems to be pushed away? Migration and refugee researcher Prof. Uma Kothari discusses how media representations of asylum seekers influence us in how we attend and respond to the plight of individuals and groups fleeing their countries in search of safety.

6.5 Changing patterns of energy use

Before considering the feasibility, and the plausibility, of radical changes in patterns of energy production and consumption, of the kind that will be needed during the first half of the twenty-first century if we are to progress towards sustainability, it is useful to recall the profound changes that have already occurred in our energy systems during the latter half of the twentieth century.

In Britain just after World War II most homes and other buildings were heated by coal. Most el

4.5 Sustainability of renewable energy sources

Renewable energy sources are generally sustainable in the sense that they cannot 'run out' – although, as noted above, both biomass and geothermal energy need wise management if they are to be used sustainably. For all of the other renewables, almost any realistic rate of exploitation by humans would be unlikely to approach their rate of replenishment by nature, though of course the use of all renewables is subject to various practical constraints.

Renewable energies are also relative

4.1 First aid

It is not required that students be trained in first aid. It is, however, important that a first aid kit is carried when you are likely to be away from immediate assistance. First aid must be rendered at once, and medical and relief help should be sought if necessary. It is important that appropriate first aid skills for use in the field are understood by those who might need them and that the procedures for enlisting help are known.

Introduction

This unit explores the topic of climate change and global warming. We will begin by exploring how the Earth’s global mean surface temperature is determined through a global “balancing act” of the rate of energy that comes from the Sun and the rate at which the planet returns that energy into space. We will also discuss the natural greenhouse effect, and how this contributes to a balanced global climate. We will then go on to consider the human impact on the atmosphere, including the imp

1.1.2 A balancing act: conservation and sustainable development

All around this coast are examples of efortsf to protect or enhance the environment. There are nature reserves, country parks and protected habitats, and the whole coastal fringe is designated as an area of scientific interest requiring special protection. There is also evidence of the need to manage the environment to ensure, so far as possible, compatibility between competing interests. Built development is prevented along the shoreline and restricted to existing settlements; caravan parks
