Which of the following can contribute to biodiversity loss?

Constructing new highways through habitats can significantly contribute to biodiversity loss because it disrupts the natural environment where various species live. Such infrastructure developments can lead to habitat fragmentation, which isolates populations and makes it difficult for species to find mates, food, and shelter. This fragmentation can also create barriers for wildlife movement, affecting migration patterns and species interactions. Additionally, highways can increase the risk of roadkill for animals and can introduce pollutants, such as oil and debris, that further degrade the habitat. Overall, the impact of new highways not only diminishes the area available for wildlife but also can lead to ecosystem imbalances, promoting the decline of certain species and the potential loss of biodiversity in the surrounding areas.

In contrast, restoring native plant species, preserving wetlands, and enhancing crop genetic diversity are all actions aimed at supporting and maintaining biodiversity. These practices focus on encouraging the growth and resilience of ecosystems rather than hindering them.
