"Environmental Degradation and Deforestation in Thailand and Cambodia"
Alan Kolata is Neukom Family Distinguished Service Professor of Anthropology, The University of Chicago. There is little doubt that climate change, deforestation, erosion, and the unequal distribution of natural resources around the globe are of pressing importance everywhere, but these problems are perhaps most acute in Asia, home to 64 percent of the world’s population. Much of this population (1 and 1.3 billion, respectively) is concentrated in India and China, two countries with rapidly g

3.2.1 What is the difference between government and governance?

Governance is from the Greek words kybenan and kybernetes, meaning ‘to steer’ and ‘pilot’ or ‘helmsman’. It is the process whereby ‘an organization or a society steers itself, and the dynamics of communication and control are central to the process’ (Rosenau and Durfee, 1995, p. 14). Of course, you could read these words as a pretty sound definition of government but that would be missing the point. Government describes a more rigid and narrower set

2.1.1 Loss of submerged plant communities

One of the symptoms of extreme eutrophication in shallow waters is often a substantial or complete loss of submerged plant communities and their replacement by dense phytoplankton communities (algal blooms). This results not only in the loss of characteristic plant species (macrophytes) but also in reduced habitat structure within the water body. Submerged plants provide refuges for invertebrate species against predation by fish. Some of these invertebrate species are phytoplankton-grazers an

2.1 Introduction

In all the analysis of stellar properties discussed so far we have made an implicit assumption - that light emitted by a star is not changed between its emission and its arrival outside the Earth's atmosphere, except by the inverse square law (i.e. it is reduced by a factor of d2, where d is the distance to the star) and by the Doppler effect. However, this may not be the case.

1.6 The human impact on the atmosphere: the coming of the industrial age

There is no doubt that CO2 is accumulating in the atmosphere. The record from Mauna Loa charts a continuing rise in CO2 concentration since measurements began in 1958, when the level was 315 ppm; the value had reached about 370 ppm by the end of the 20th century, and hit more than 378 ppm in 2004. Important as changes in atmospheric CO2 undoubtedly are (see below), we need to be aware that this is not the whole story of human-induced greenhouse forcing. In par

5.2 Air pollution

There are many popular beliefs about air quality and health. As a child you might have been exhorted to, ‘go out and play in the nice fresh air’. Mountain air is often regarded as being particularly beneficial, especially for those who are recuperating from or suffering some types of respiratory diseases.

2 Your own mathematics

It is crucial to remember that you are a learner of mathematics as well as a teacher. In this course you will be asked to undertake some mathematical tasks. The aim of these tasks is not to improve your mathematics, but to give you experience of doing mathematics for yourself—experience that you can reflect upon subsequently. The reflection is used to develop your awareness of the ways that learners deal with mathematical tasks, and how learners' mathematical thinking is influenced by the w

Schoolhouse Rock! Interplanet Janet
This classic music video from School House Rock sings about the solar system and individual planets.  The song will address many facts such as which planet is known as the red planet, which planet has a funny tilt, and what is the largest planet. Although the song is outdated (naming Pluto as the 9th planet) it is still an enjoyable and informative song.  (03:06)
