How do humans cause extinction?
Humans can cause extinction of a species through overharvesting, pollution, habitat destruction, introduction of invasive species (such as new predators and food competitors), overhunting, and other influences. Explosive, unsustainable human population growth is an essential cause of the extinction crisis.

These experts calculate that between 0.01 and 0.1% of all species will become extinct each year. If the low estimate of the number of species out there is true – i.e. that there are around 2 million different species on our planet** – then that means between 200 and 2,000 extinctions occur every year.
Are dinosaurs extinct?
Other than birds, however, there is no scientific evidence that any dinosaurs, such as Tyrannosaurus, Velociraptor, Apatosaurus, Stegosaurus, or Triceratops, are still alive. These, and all other non-avian dinosaurs became extinct at least 65 million years ago at the end of the Cretaceous Period.
What is the 6th extinction?
The Holocene extinction, otherwise referred to as the sixth mass extinction or Anthropocene extinction, is an ongoing extinction event of species during the present Holocene epoch (with the more recent time sometimes called Anthropocene) as a result of human activity.
How do humans hurt animals?
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.
How much longer can we live on Earth?
The planet could remain at an obliquity of 60° to 90° for periods as long as 10 million years.
