What environmental action is focused on preserving natural habitats?

The environmental action that focuses on preserving natural habitats is controlling surface erosion. This process plays a crucial role in maintaining the integrity of ecosystems. By preventing soil erosion, we help ensure that natural habitats remain intact, which is vital for various plant and animal species that depend on these environments for survival. Erosion control measures, such as planting vegetation, using erosion control blankets, and implementing sustainable farming practices, contribute directly to protecting the natural landscape and promoting biodiversity.

The other options, while important in their contexts, do not specifically address the preservation of natural habitats. Access to housing pertains more to social issues, worker safety and training are focused on labor conditions, and hours of work relate to employment practices, none of which are directly linked to environmental actions or the preservation of habitats.
