Planting trees, reducing pollution, and protecting wildlife are all examples of what?

The correct answer, conservation, encompasses a wide range of activities focused on the protection and management of natural resources and ecosystems. Planting trees contributes to the restoration of habitats and improves air quality, while reducing pollution directly benefits the health of various ecosystems. Protecting wildlife ensures that species remain viable and contributes to biodiversity, which is crucial for the resilience of ecosystems.

These actions collectively aim to sustain natural environments for future generations, addressing environmental challenges and promoting ecological balance. In contrast, the other options—engineering, manufacturing, and urbanization—do not inherently focus on the sustainable management of natural resources or the protection of ecosystems. While they may intersect with conservation efforts, they are primarily oriented towards development, production, and human-centric improvements rather than the safeguarding of the environment.
