The activity that might reduce habitat loss is:
spreading out the human population
This approach can help alleviate the pressure on specific habitats by minimizing the impact of concentrated human development, allowing for more natural habitats to be preserved and reducing fragmentation.
While removing invasive species can benefit specific ecosystems and replacing golf courses with farms can support local agriculture, spreading the population out generally provides more space for natural habitats to remain intact compared to concentrated human activity. Draining wetlands, on the other hand, would negatively impact habitats.
