the  formation of new species through the process of evolution.

Speciation 

100

National parks, nature reserves are examples of this strategy 

In Situ - Habitat based conservation 

100

__________ & __________ are in the physical category of measuring water quality 

Temperature and Turbidity 

100

Provide energy for freshwater and marine food webs 

Phytoplankton 

100

The value that a thing has in and of itself because it exists 

Intrinsic Value 

200

occurs because genetic diversity within a population gives rise to variation among individuals.

Natural Selection 

200

Zoos, botanical gardens and seed banks are examples are of this strategy 

Ex Situ - Species Based Conservation 

200

occurs when water bodies receive an excess input of nutrients, such as nitrates and phosphates. Can cause algae blooms 

Eutrophication 

200

Largest long term catch that can be sustained without depleting fish stocks 

Maximum Sustainable Yield 

200

The ability of a biological area to provide on going natural resources, while naturally absorbing waste and production 

Biocapacity 

300

Process by which species change over time through mutation, genetic drift, gene flow and natural selection 

Evolution 

300
This strategy works on restoring natural processes in ecosystems by reintroducing key species 
Rewilding 
300

Measures the amount of oxygen required by microorganisms to break down organic matter 

Biochemical Oxygen Demand (BOD) 

300

Farming of fish, molluscs, crustaceans and aquatic plants in controlled environments 

Aqua Culture 

300
The right of all people to live in a pollution free environment and have equitable access to natural resources, regardless of race, gender, socio-economic status. 

Environmental Justice 

400
Capacity of ecosystems to withstand and recover from disruptions 
Resilience 
400

Zones that is strictly protected for biodiversity with no human activity 

Pristine Core 

400

The complete absence of dissolved oxygen in water, due to algae blooms 

Anoxia 
400

The reliable access to sufficient quantities of safe, clean water to meet the needs of individuals, communities and ecosystems. 

Water Security 

400

The area of land and water required to sustainably provide all resources at the rate of consumption by a given human population 

Ecological Footprint 
500

The three main levels of Biodiversity 

Genetic, Species, Habitat 

500

Responsible travel to natural areas, which conserves the environment and sustains the well being of local people. 

Ecotourism 

500
Major sources of pollutants 

Industrial waste, sewage, agricultural runoff, Garbage, oil spills and burning of fossil fuels 

500

4 examples of Water conservation techniques 

Water Rationing, metering, grey water, low flush toilets, rainwater harvesting, greenhouses, drip irrigation, drought resistant crops 

500

a concept that defines the environmental limits within which humans can survive and develop 

Planetary boundaries
