A variable that the scientist measures during and after the experiment in order to determine the results is called this
What is a dependent variable?
Marks placed on products that explain how the products were grown, harvested, or manufactured are called this
What are ecolabels?
This type of tax is imposed on companies that participate in activities or produce products that are harmful to the environment
What is a green tax?
This type of feedback loop increases the amount of change in the environment, which drives it out of balance
What is a positive feedback loop?
When the oxygen in water is depleted by decomposition of an algae bloom, this type of zone can form in the water
A testable idea that attempts to explain a phenomenon or answer a scientific question is called this

This field of economics that argues that economies are unsustainable if resource use is not made more efficient
What is environmental economics?
