Document Summary

Class 2: ethics, values, and sustainability & how we think about the environment. Factors in the collapse of easter island society. Island environment: very clear limits on availability of resources, growth and movement of population. Highly stratified society unwilling or unable to adapt to changing environmental conditions. Introduction of alien chemical & organisms into the environment. Cumulative: changes of similar nature in multiple regions have global consequences. A number of small changes over time combine to have a large impact. Ancient civilizations were all keenly interested in how environmental processes affect human activities and well-being. Science breaks from creationism in 19th century. Lamarck, darwin, agassiz humans evolved from non-human ancestors. Malthus: human population numbers governed by food supply. Suggests that human activities are dictated by the environment. Reaches apogee in early 20th century when some geographers argue that racial stereotypes are manifestations of environmental conditions (semple, huntington)

c) Are there other factors besides population size that can have an impact on resource consumption and environmental conditions in a country?

Please Help. Thank you very much.

Ecology is the study of how organisms interact with their environment. Thus, a central question in ecology concerns how organisms respond to environmental variation. The flip side of this question is to ask whether the variation in characteristics of organisms is the result of variation in features of the environment. This variation can occur in space or through time.

1. Make a list of all the environmental variables that you can think of that are likely to be important to organisms. Think about plants and microbes as well as animals.

1A. One environmental change of great concern to us is climate change, specifically the prospect of human-caused global warming, a topic to which we will return. How do organisms respond to this spatial and temporal variability in the environment?
