Document Summary
Environmentalism: 1) activism focused on protecting the natural environment, particularly from the impacts of human activities; 2) activism- public education programs, advocacy and legislation. Ecology: scientific study of the relationships between organisms and their environment. Environment- all external factors that influence its survival, growth, and/or reproduction, directly or indirectly: habitat: the surroundings that the organism lives, abiotic: non-living, biotic: living component that the organism interacts with. Environmental factors are either resources or conditions. Resources: consumed by the organism, making them less available for others, eg. food, water, mates. Conditions: influence the organism but are not consumed, eg. temperature, acidity. Hazards: negatively affect the organism, eg. substances or natural disasters. Note: environment is defined relative to the individual. 1. 2 history of ecology: ecology is rooted in many scientific disciplines.
