Final answer:
A social benefit of sustainable waste management is the conservation of natural habitats for wildlife, which results from reducing the need for landfills and preserving biodiversity.
Step-by-step explanation:
The statement that describes a social benefit of sustainable waste management is that there will be more land available for wild animals. By managing waste in a sustainable way, such as through composting, methane capture, and waste-to-energy processes, the need for expanding landfills decreases, which helps in preserving natural habitats for wildlife. This is crucial because the removal of waste often requires the destruction of such habitats, leading to a decrease in biodiversity. Therefore, sustainable practices contribute not only to waste reduction but also to the conservation of ecosystems.
