Human Impact on Ecosystems
Chapter 5 Vocabulary air pollution emissions photochemical smog ozone acid rain ozone layer chlorofluorocarbons (CFCs) greenhouse effect global warming.
Energy Resources Essential Question: How do energy resources affect the environment?
Overpopulation ~7 billion people Many natural resources are nonrenewable More people means: –1) More forests removed –2) More resources consumed –3)
AND SOLUTIONS! Environmental Issues. The environment is all connected! (p.87) Environmental issues fall into three general categories: 1. Human population.
Introduction to Environmental Engineering. What is Environmental Engineering? Definition: The application of science and engineering knowledge and concepts.
CHAPTER 6 HUMANS IN THE BIOSPHERE
How do we influence the environment?
HUMANS IN THE BIOSPHERE. A Changing Landscape Growing populations depend on the limited natural resources of earth for survival. Humans rely on ecological.
Biomes and Conservation
The main cause of climate change is the greenhouse effect. This is the warming of the surface or lower atmosphere of a planet. This is caused.
Pollution. Smog smog – mixture of chemicals that forms a haze in the air (Nitrogen Oxides etc) smoke from cars and factories release the chemicals.
Vocabulary 6-2 Renewable resources --- Resources that are naturally replaced. Ex. sunlight, wind, and trees. Non-renewable resources --- Resources that.
Global Change and the Human Impact. Environmental services and goods Q: What are some services you get from the environment? Renewable They can be used.
Unit 4 Human Impact on the Environment. Population Three factors that affect population: –Number of births –Number of deaths –Number of individuals that.
