Final answer:
Two crucial ecosystem services are water purification by wetlands and climate regulation by forests. Industrial pollution can degrade wetlands' water filtration capacity, while deforestation negatively impacts the carbon absorption capacity of forests, leading to climate change.
Step-by-step explanation:
The question pertains to the identification of two ecosystem services and the description of one anthropogenic activity that negatively impacts each service.
Ecosystem Service 1: Water Purification
Wetlands perform an essential ecosystem service by filtering pollutants from water, thereby maintaining water quality. An anthropogenic activity that negatively impacts this service is the release of industrial pollutants into water bodies, which can overwhelm the natural filtration ability of wetlands and lead to water degradation.
Ecosystem Service 2: Climate Regulation
Forests play a critical role in climate regulation by absorbing carbon dioxide from the atmosphere. Deforestation, often driven by the conversion of forests to agricultural land, is an anthropogenic activity that severely undermines this service, leading to increased greenhouse gas concentrations and global warming.
