Name a benefit of maintaining biodiversity for humans.

Maintaining biodiversity is crucial for humans because it provides a wide array of resources essential for survival and well-being. Biodiversity encompasses the variety of life forms and ecosystems that contribute to ecosystem services, which include the provision of food, medicines, and clean water. A diverse array of species can improve agricultural productivity by enhancing soil health, pest control, and pollination processes, all of which are vital for food security. Additionally, the genetic diversity found within and among species is essential for developing new medicines and maintaining healthy ecosystems that regulate water quality and availability. The complex interactions among various organisms in a biodiverse ecosystem help ensure resilience against diseases and environmental changes, further supporting human needs.

In contrast, other options highlight negative aspects that do not align with the benefits of biodiversity. For instance, decreasing agricultural productivity and limiting access to clean water are detrimental outcomes, while creating more waste in ecosystems also poses challenges rather than aiding human welfare. Thus, the choice highlighting the provision of resources encapsulates the significant benefits that biodiversity offers to human populations.
