Document Summary
Env - session 3: introduction to environmental science (ii) (14-9-15) Laws usually when the theory is impossible to prove wrong (ex gravity) Our perception is influenced by worldviews: (do not memorize specific types) Ex affluence vs. poverty we think ddt (pesticide) is bad (hurts eagles/ biodiversity) but in places like south africa poor people will think its good because it defends against malaria. Over the past 50 years, humans have changed ecosystems more rapidly and extensively than in any comparable period of time in human history. This has resulted in a substantial and largely irreversible loss of diversity of life on earth. Ecosystem services chart: ecosystems are provisioning and provide us with things like water. They regulate carbon in the atmosphere and recreational use, and much more. Population, poverty, and over-consumption are root problems. Sustainable development: use of resources to satisfy current needs without compromising future availability of resources.
