  1. Destruction of their habitat

  2. Increasing human population

  3. Introduction of new species

  4. All of the above

Show answer
Correct Option: D
Explanation:

  • Habitat destruction occurs when natural habitats are no longer able to support the species present, resulting in the displacement or destruction of its biodiversity.
  • The growth of the human population has impacted the planet and affected biodiversity. The need for food, space and raw materials has resulted in the destruction of habitats and pollution.
  • Introduction of invasive species causes harm to wildlife in many ways. When a new and aggressive species is introduced into an ecosystem, it may not have any natural predators or controls. Invasive species can also alter the abundance or diversity of species that are important habitat for native wildlife.
So, the correct answer is 'All of the above'.
