GEOG 2EI3 Lecture Notes - Lecture 9: Millennium Ecosystem Assessment, Millennium Development Goals, Demographic Transition
Document Summary
Environment and resources unit 1: change and challenges. Slide 3: humans have constantly experienced changes (i. e. the ice-age that started in the medieval times and ended in the 19th century during which people in europe experienced a return of cold glacial conditions) Slide 4: variation is constant in natural systems (i. e. the oscillations between cold glacial periods and warm inter glacial periods over the past several hundreds of thousands of years) Slide (cid:1009): cha(cid:374)ges i(cid:374) (cid:374)atu(cid:396)al s(cid:455)ste(cid:373)s see(cid:373)i(cid:374)gl(cid:455) a(cid:396)e (cid:374)o(cid:449) (cid:373)o(cid:396)e a(cid:271)(cid:396)upt.

These changes are due in part to how humans are interacting with natural systems in their activities.
