Question
Which of the Planetary Boundaries we have already breached?
- a. All of the above
- b. Freshwater use
- c. CO2 concentration in atmosphere
- d. Biosphere integrity
Solution
To determine which of the Planetary Boundaries we have already breached, we need to evaluate the options provided:
-
Freshwater use: There is significant evidence that freshwater resources are being depleted faster than they are replenished in many areas.
-
CO2 concentration in the atmosphere: The atmospheric CO2 levels have surpassed 400 ppm, indicating a breach of this boundary related to climate change.
-
Biosphere integrity: The loss of biodiversity and ecosystems suggests that we have also breached this boundary.
Given that all three boundaries are critical in assessing the health of the Earth's systems, and based on current scientific consensus, one could deduce that:
Final Answer
a. All of the above.
