Dinosaurs are good examples of animalsthat are extinct and no longer roam Earth. Animalsand plants that are at risk of becoming extinctbecause of threats from changing environments or predators are considered threatened or endangered.https://wonderopolis.org/wonder/how-does-a-species-become-endangered]]> 2017-12-11 19:50:43 UTC https://padlet.com/rniemann_2025/37c7yuv8qqa1/wish/215198475 rniemann_2025 https://padlet.com/rniemann_2025/37c7yuv8qqa1/wish/216631921
he earth teems with life: thousands of species of vertebrate animals (mammals, reptiles, fish and birds); invertebrates (insects, crustaceans, and protozoans); trees, flowers, grasses and grains; and a bewildering array of bacteria, algae and other single-celled organisms, some inhabiting scalding-hot deep-sea thermal vents. And yet, this rich profusion of flora and fauna seems paltry compared to the ecosystems of the deep past: by most reckonings, since the beginning of life on earth, a whopping 99.9 percent of all species have gone extinct. Why? You can get some idea by perusing the following 10 slides.

When we demolish a forest in a certain area, we have doomed all the living things thriving in that environment. When we cut off rivers with dams or build roads through a forest, we are destroying ecosystems. www.theworldcounts.com/stories/Why-Do-Species-Become-Extinc
