Biocapacity is synonymous with ecological demand.
Answer: False
Biocapacity, also known as biological capacity, represents an ecosystem's ability to regenerate resources and absorb waste. Ecological demand, conversely, is measured by the ecological footprint. Therefore, biocapacity is not synonymous with ecological demand.
Biocapacity is utilized in sustainability studies to measure human impact on the environment when paired with the ecological footprint.
Answer: True
Biocapacity, when considered alongside the ecological footprint, serves as a critical metric for assessing human impact on the environment within the field of sustainability studies.
The United Nations developed the concepts of biocapacity and ecological footprint.
Answer: False
The concepts of biocapacity and ecological footprint were developed by the Global Footprint Network, not the United Nations. The UN, however, is a source for data used in their calculations.
Biocapacity is defined as the environmental demand of a regional ecosystem.
Answer: False
Biocapacity refers to the capacity of ecosystems to regenerate resources and absorb waste. The environmental demand of a regional ecosystem is represented by the ecological footprint, not biocapacity.

What does it mean when humanity is described as using "1.7 Earths"?
Answer: Humanity is consuming renewable resources at a rate 1.7 times faster than they can regenerate.
Describing humanity's consumption as "1.7 Earths" signifies that renewable resources are being consumed at a rate 1.7 times faster than the planet's capacity to regenerate them, leading to resource depletion.
An increase in the global human population generally results in an increase in biocapacity per person.
Answer: False
An increase in the global human population typically leads to a decrease in biocapacity per person. This occurs because the Earth's finite resources must be distributed among a larger number of individuals, thereby increasing per capita demand.
A biocapacity deficit is identified when the ecological footprint is less than the available biocapacity.
Answer: False
A biocapacity deficit occurs when a population's ecological footprint, representing its demand on nature, exceeds the biocapacity, which is the planet's ability to regenerate resources and absorb waste. Therefore, a deficit is indicated when the footprint is *greater* than the biocapacity.
Relying on net imports and overusing one's own ecosystems are two primary sources contributing to a biocapacity deficit.
Answer: True
A biocapacity deficit can arise from multiple sources, including the overuse of one's own ecosystems (overshoot) and reliance on net imports of resources.
The primary driver of global ecological overshoot is the reduction of carbon dioxide emissions.
Answer: False
The dominant factor contributing to global ecological overshoot is not the reduction but rather the *increase* in carbon dioxide emissions, primarily resulting from the burning of fossil fuels.
Climate change and ocean acidification are environmental stresses that can alleviate ecological overshoot.
Answer: False
Climate change and ocean acidification are identified as environmental stresses that *aggravate*, rather than alleviate, the problem of ecological overshoot. They represent consequences of exceeding planetary limits.
Consuming resources that should regenerate within one year over a period of one year and eight months signifies that humanity is living within Earth's biocapacity.
Answer: False
Consuming resources that require one year to regenerate over a period of one year and eight months indicates that humanity is consuming resources at a rate faster than they can be replenished. This signifies living beyond Earth's biocapacity, not within it.

If a population's ecological footprint is greater than its biocapacity, it signifies that the population is living sustainably within its resource limits.
Answer: False
If a population's ecological footprint exceeds its biocapacity, it indicates that resource demand surpasses the ecosystem's regenerative capacity, signifying unsustainable living and a biocapacity deficit.
How does an increase in the global human population generally affect the Earth's biocapacity per person?
Answer: It decreases biocapacity per person due to resource sharing.
An increase in the global human population typically leads to a decrease in biocapacity per person, as the Earth's finite resources must be shared among a larger number of individuals, thus increasing per capita demand.

If a population's ecological footprint is greater than its biocapacity, what does this indicate?
Answer: The demand for resources exceeds the ecosystem's ability to regenerate them.
When a population's ecological footprint surpasses its biocapacity, it signifies that the demand for resources and ecosystem services exceeds the environment's ability to regenerate them, leading to a deficit.
What does the term "overshoot" refer to in the context of biocapacity deficits?
Answer: The overuse of one's own ecosystems.
In the context of biocapacity deficits, "overshoot" refers to the condition where a population overuses its own ecosystems, thereby contributing to the deficit.
