Why do we study environmental indicators?
Environmental indicators are essential tools for tracking environmental progress, supporting policy evaluation and informing the public . Since the early 1990s, such indicators have gained in importance in many countries and in international fora.
Which environmental indicators provides evidence for human impact on the natural world?
The indicators are biodiversity, food production, average global surface temperature and CO2 concentrations , human population, and resource depletion.
What is an example of an environmental indicator?
Environmental indicators can be measured and reported at different scales. For example, a town may track air quality along with water quality and count the number of rare species of birds to estimate the health of the environment in their area.
What are the main environmental indicators?
We will focus on five global-scale environmental indicators: biological diversity, food production, average global surface temperature and carbon dioxide concentrations in the atmosphere, human population, and resource depletion . These key environmental indicators help us analyze the health of the planet.

Why do environmental scientists study chemicals?
Environmental chemists study how chemicals – usually contaminants – move through the environment . This is referred to as chemical “fate and transport”. They also study the effects of these contaminants on ecosystems, animals, and human health.
