Interpreting Environmental Data

A 2020 report on the state of the global environment found two key trends: 1) The population sizes of mammals, birds, fish, amphibians, and reptiles fell by an average of 68% between 1970 and 2016. 2) Humanity's consumption of natural resources is 56% greater than the planet's ability to regenerate them. Based on these two findings, what is the most logical conclusion about their relationship?

Evaluating Global Environmental Trends

A major 2020 report on the state of the global environment concluded that, on average, the population sizes of vertebrate species (mammals, birds, fish, amphibians, and reptiles) saw a net growth of 68% between 1970 and 2016.

A 2020 report on the global environment presented several key findings. Match each key finding to its correct description.

A major 2020 report on the global environment stated that humanity's consumption of natural resources is overusing the Earth's capacity to regenerate them by at least ____%.

A 2020 report on the global environment detailed historical trends and projected future outcomes for biodiversity. Based on the report's findings, arrange the following events in the correct chronological and logical order, from the earliest historical period to the potential future recovery.
