Question

In what ways humans affect animals population?

Answer 1

Answer:

People affect animals through four broad types of activity: (1) people keep companion, farm, laboratory and captive wild animals, often while using them for some purpose; (2) people cause deliberate harm to animals through activities such as slaughter, pest control, hunting, and toxicology testing.

(3) people cause direct but unintended harm to

animals through crop production, transportation, night-time lighting, and many other

human activities; and (4) people harm animals indirectly by disturbing ecological systems

and the processes of nature, for example by destroying habitat, introducing foreign

species, and causing pollution and climate change. Each type of activity affects vast

numbers of animals and raises different scientific and ethical challenges. I

Answer 2

Humans are now responsible for causing changes in the environment that hurt animals and plant species. We take up more space on Earth for our homes and cities. We pollute habitats. Human activity often changes or destroys the habitats that plants and animals need to survive.
