Question

students are investigating carbon geoengineering, also known as carbon dioxide removal (cdr) of carbon dioxide from the atmosphere. they wonder how this technology can be used as a by activity. which action can cdr help reverse in order to improve biodiversity in the environment? a air pollution due to the use of fossil fuels b invasive species introduced to control pests c water pollution due to use of fertilizer runoff d species loss due to hunting and habitat destruction

Explanation:

Carbon dioxide removal (CDR) is related to addressing issues caused by human - made activities. Air pollution due to fossil fuel use releases carbon dioxide. By reducing air pollution (which is a major source of carbon dioxide emissions from fossil fuels), CDR can be effectively implemented. Invasive species introduction (B) is about ecological disruption not directly related to carbon dioxide from the atmosphere. Water pollution due to fertilizer runoff (C) is a water - related issue. Species loss due to hunting and habitat destruction (D) is a biodiversity issue mainly related to human activities on land and wildlife, not directly to carbon dioxide removal in the context of air pollution from fossil fuels.

Answer:

A. air pollution due to the use of fossil fuels
