Changing Human Geographies 01:42 Global Challenges: A World Without Us?
Changing Human Geographies 01:42 Norton, Chapter 3 History of humanity = a history of human impacts on the environment (is humanity a part of nature?) These impacts are, in part, a direct result of the survival instincts of the species impacts; also, result from negligence, greed, etc. Some/many impacts pose serious threats to the survival of the species and the future of the planet/ Human impacts: the consequences of any human activity on the physical environment Examples: deforestation, climate change, pollution, desertification, habitat destruction, species extinction, etc. Question: how/why do these impacts occur? Anthropocentric view – human existence is the source of all value; resource are for human use Example: Why is there pollution? Environment movement - product of 1960s Rachel Garson - Silent Spring Human impacts dependent on: Population (numbers) Affluence (per capita income)  how people are living Technology (labour vs. Energy intensive) The Evolution of Human Impacts Palaeolithic Period (early Stone Age) 1.5 million years B.P Possible Impacts - use of fire for hunting
Changing Human Geographies 01:42 Large scale destruction of vegetation; extinction of megafauna Neolithic Period (late Strong Age) Up to early Holocene Possible impacts -origins of agriculture (breeding plants/animals) Wild species lost to domestication Holocene – Anthropocene Most recent 10,00 years Population and affluence increase, technology increased variety of impacts Industrial Revolution 18 th century to present Earth’s Vital Signs (Norton, pp. 115-117) Catastrophists ( Pessimistic- doom and gloom ) vs. Cornucopians ( Optimistic- we have a change to make difference and save world) Who is right Who should we believe ... it is difficult to separate the many very real problems from the numerous exaggerated claims” (Norton, p.115) Question: is global warming (p. 108- 115), a “very real problem” or an “exaggerated claim”? How can we respond to an uncertain future? New technologies to counteract impacts Adaptation to environmental change Conservation New philosophy ( see table 3.2, p.95)
Changing Human Geographies 01:42 Sustainability/ Sustainable Development Defined as: development that meets the needs of the present without compromising the ability of future generations to meet their needs (p.118) But, is this possible? Is this realistic? Does it make sense? Dr. Peace is very sceptical about this definition Summary Complexity of human-environment relations Complex interdependence of factors which underlie human impacts (political, economic, social, etc.) 3 Contentious issues (p. 93) What is the relationship between environmental quality and the economy?
