GEOG 106 Lecture Notes - Lecture 32: Water Cycle, Parks Canada, Habitat Destruction
Document Summary
Produce rapid and long- term increases in abundance, diversity and productivity of marine organisms. Lessen the livelihood of extirpation of species outside of marine reserves: Can create a spill over effect when individuals of protected species spread outside reserves. Allow larvae of species protected within reserves to seed the seas . Canada = marine reserves are managed by parks canada through the national marine conservation areas programs: water resources. Groundwater 0. 6% (major source of fresh water) Salt water - > cooled fukushima nuclear (core) water. Available fresh water: 0. 003% of total supply. 40 times more available from groundwater than from surface water (lakes, rivers, wetlands, etc. ) Hydrological cycle provides 577,000 km3 fresh water per annum. Enough to supply the world"s population at 5- 10 times the current size. Water stress supplies of water less than 17000m3 water per year per person ; expected to increase from 2. 3 billion people to 3. 5 billion people.
