Which of the following is an example of human modification to the physical environment that has a negative global impact?

Building terraces is a sustainable agricultural practice that helps prevent soil erosion and enhances water retention. While it modifies the physical environment, its primary aim is to improve land use efficiency and sustainability, thus having a generally positive environmental impact.

The catch and release technique is designed to minimize harm to fish populations and support sustainable fishing practices. Although it modifies the environment by temporarily disturbing aquatic ecosystems, it promotes conservation and the health of fish populations, making it a less impactful choice on a global scale.

Planting native trees is a beneficial practice that restores ecosystems, improves air quality, and enhances biodiversity. This modification positively contributes to the physical environment and helps combat climate change, making it a proactive approach rather than a harmful one.
