With the rapidly growing human population and constant new pressures on the environment it gradually becomes more difficult to maintain sustainability. Choose the sentence which best explains what sustainability is.
The exploitation of resources at such rate which allows for their natural replenishment and the recovery of the ecosystem affected by their use.
The maximum population size that an area can support without detrimental effects.
Engaging in the prevention of negative effects of human activities on the Earth’s resources through localised actions (recycling of waste, reduction in electricity consumption etc.).
The area of land needed to provide all of the resources for a person’s lifestyle and to dispose of all their wastes.

ecocentric
anthropocentric
technocentric
Nature-centered value system that views people as being under nature's control rather than in control of it.

Murphy's Law
This is also known as dynamic equilibrium and is a stable form of equilibrium that allows a system to return to its steady state after a disturbance.
steady-state equilibrium
unstable equilibrium
feedback
static equilibrium
This is the tendency of a system to maintain stability and resist tipping points.
resilience
entropy
feedbacks
static equilibrium
The minimum amount of change within a system that will destabilize it and cause it to reach a new equilibrium or stable state.
tipping point
resilience
sustainability
feedback
particular world view or set of paradigms that shapes the way individuals or societies perceive and evaluate environmental issues
environmental movements
environmental value systems
