A few threats to biodiversity include urbanization and the construction of new roads, the increasing human population, the transportation industry and owning exotic pets. Biodiversity may also be threatened by introducing non-native species into an environment, poor human health, activities of large corporations, consuming meat, not recycling and eliminating insects.
The construction of new roads destroys animals' habitats. An increasing human population means that more land must be converted for food production. Cars in the transportation industry give off emissions that contribute to pollution. Large corporations produce chemicals that leach into the soil and water. Introducing non-native species into an area may causes the destruction of the native habitat, threatening species that are native to the area.
