4.2 Capitalism – naturally

Business can learn to integrate ecological thinking into the core of its thinking and become the hub of a sustainable society. This is the claim of the business learns position. As environmentalists have spent over 30 years portraying business as the arch-villain of the piece, this is a grand claim. One of the people who have stated it most clearly is Ray Anderson, head of the US carpet giant Interface (Author(s): The Open University

Ms. Latitude and Mr. Longitude
Students often confuse latitude lines and longitude lines.  They can remember that the terms are lines on a map, but can't remember which is which.  This brief video clip shows a trick that Mrs. Matthews students use to help them remember the difference. They create artwork showing Mr. or Ms. Latitude (with an attitude) and Mr. or Ms. Longitude (with everything long).

7.1 Climate models

To understand climate change it is necessary to construct climate models, to explore and predict interactions between different factors. Models are tested for accuracy against known sets of data, before being run forward to predict future changes.

2.5.1 Quantum mechanics and chance

The real quantum revolution dates from the formulation of quantum mechanics by Werner Heisenberg (1901-1976) and others in 1925, and its physical interpretation by Max Born (1882-1970) in 1926. However, before attempting even the most basic sketch of quantum mechanics let's take a small diversion into the realm of philosophy.

The basic working philosophy of most scientists, including those who say they have no philosophy, is a kind of realism. (Philosophers recognise many

1.1 How has the human population grown?

For most of human history there have been relatively few people in the world. Figure 2 shows that only over the last 50 years have numbers really shot up, and that, at the turn of the century, the population reached over six billion.

2.5.2 Environmental indicators

The notion of a link between climatic conditions and the behaviour of plants and animals (e.g. the growth of trees or coral) and the composition of natural communities or ecosystems (the type of vegetation in a given area, say) is fundamental to the use of proxy data to reconstruct past climates. Some examples of biological responses to recent climate change were included in Box 9. Here we should be wary of jumping to conclusions. Such changes involve complex living systems that can respond i
