Document Summary
Human impact 1: population growth has affected resource availability, current pop. It is necessary to educate people and bring about laws (legislation) if the public is not ready to change themselves: western culture (capitalism) has different ethics in regards to the environment than native culture (more holistic view) What is an environmental problem: an undesirable change, what constitutes undesirable change depends on perception, varies with age, culture, education level, worldview, ex. Pesticide ddt: thought safe in 1945, known to be toxic today, still used widely in africa to combat malaria. Global warming = effects of gases releases by factories melting of ice. Alternative energy sources (less pollution but can be costly) around large bodies of water. Deforestation: unusable trees are burned (source of co2) Habitat loss and species endangerment: the arctic is effected the most by global warming, permafrost is beginning to melt; more co2 + gases released.
