Answer :
Final answer:
Unregulated fishing disrupts ocean food webs, deforestation impacts the carbon cycle, agriculture alters landscapes
Explanation:
A negative environmental effect is that unregulated fishing in the ocean can disrupt the interactions between organisms in existing food webs. Overfishing can lead to the extinction of fish species and disrupt the balance in aquatic ecosystems, impacting biodiversity and overall ecosystem health.
Deforestation reduces the number of trees that use carbon dioxide and store carbon in plant fibers. The burning of wood or carbon-based energy sources releases carbon back into the atmosphere, contributing to climate change and disrupting the carbon cycle essential for regulating the earth's temperature.
One characteristic example of human impact on the environment is through agriculture, where native vegetation is cleared for farming and combustion, altering landscapes and affecting biodiversity. This practice can lead to changes in ecosystems, soil quality, and land use patterns, influencing environmental sustainability.
