What do we call meeting the
needs of the present without
compromising the ability of future
generations to meet their needs?
Sustainability
What do we call a detectable change in global temperatures?
Climate change or global warming.
What are the three age group categories of dependency?

Sceptic (Br. spelling), or skeptic (US spelling).
What do we call government policies promoting childbirth?
Pronatalist policies.
What is primary ecological succession?
The process that occurs when newly formed or newly exposed land with no species present is gradually colonized.

Evolutionarily Distinct and Globally Endangered
What do we call algae found in the upper parts of the ocean?
Phytoplankton
Sampling technique where points of sampling are selected by chance rather than choice.
Random sampling
What do we call the study of how populations change in size and structure over time?
