Biodiversity
the formation of new species through the process of evolution.
Speciation
National parks, nature reserves are examples of this strategy
In Situ - Habitat based conservation
__________ & __________ are in the physical category of measuring water quality
Temperature and Turbidity
Provide energy for freshwater and marine food webs
Phytoplankton
The value that a thing has in and of itself because it exists
Intrinsic Value
occurs because genetic diversity within a population gives rise to variation among individuals.
Natural Selection
Zoos, botanical gardens and seed banks are examples are of this strategy
Ex Situ - Species Based Conservation
occurs when water bodies receive an excess input of nutrients, such as nitrates and phosphates. Can cause algae blooms
Eutrophication
Largest long term catch that can be sustained without depleting fish stocks
Maximum Sustainable Yield
The ability of a biological area to provide on going natural resources, while naturally absorbing waste and production
Biocapacity
Process by which species change over time through mutation, genetic drift, gene flow and natural selection
Evolution
Measures the amount of oxygen required by microorganisms to break down organic matter
Biochemical Oxygen Demand (BOD)
Farming of fish, molluscs, crustaceans and aquatic plants in controlled environments
Aqua Culture
Environmental Justice
Zones that is strictly protected for biodiversity with no human activity
Pristine Core
The complete absence of dissolved oxygen in water, due to algae blooms
The reliable access to sufficient quantities of safe, clean water to meet the needs of individuals, communities and ecosystems.
Water Security
The area of land and water required to sustainably provide all resources at the rate of consumption by a given human population
The three main levels of Biodiversity
Genetic, Species, Habitat
Responsible travel to natural areas, which conserves the environment and sustains the well being of local people.
Ecotourism
Industrial waste, sewage, agricultural runoff, Garbage, oil spills and burning of fossil fuels
4 examples of Water conservation techniques
Water Rationing, metering, grey water, low flush toilets, rainwater harvesting, greenhouses, drip irrigation, drought resistant crops
a concept that defines the environmental limits within which humans can survive and develop
Planetary boundaries
