What we lose when animals go extinct?
The Biggest Threat: Humans. Habitat loss — driven primarily by human expansion as we develop land for housing, agriculture and commerce — is the biggest threat facing most animal species, followed by hunting and fishing. Even when habitat is not lost entirely, it may be changed so much that animals cannot adapt.
Where did people come from?
Humans first evolved in Africa, and much of human evolution occurred on that continent. The fossils of early humans who lived between 6 and 2 million years ago come entirely from Africa. Most scientists currently recognize some 15 to 20 different species of early humans.

Emergence of Earth At first, it was thought that the Earth’s atmosphere consisted of hydrogen compounds—methane, ammonia and water vapor—and that life began under such reducing conditions, which are conducive to the formation of organic molecules.
Why are animals endangered?
Species become endangered for two main reasons: loss of habitat and loss of genetic variation. A loss of habitat can happen naturally. Human activity can also contribute to a loss of habitat. Development for housing, industry, and agriculture reduces the habitat of native organisms.
What would happen if all animals went extinct?
Wild forests and grasslands would die because they are adapted to rely on animal decomposers as well as pollinators and seed dispersers. This would cause abrupt loss of rainfall, atmospheric change and climate change. Widespread starvation combined with lack of decomposition would cause rampant disease.
Why should we save endangered animals essay?
Healthy ecosystems depend on plant and animal species as their foundations. When a species becomes endangered, it is a sign that the ecosystem is slowly falling apart. Each species that is lost triggers the loss of other species within its ecosystem. Humans depend on healthy ecosystems to purify our environment.

Why endangered animals should be saved?
Plants and animals maintain the health of an ecosystem. And, when species become endangered, it’s a sign that an ecosystem is out of balance. But the balance within an ecosystem isn’t always easy to maintain: the loss of one species often triggers the loss of others. …
Are humans monkeys?
Humans and monkeys are both primates. But humans are not descended from monkeys or any other primate living today. But humans and chimpanzees evolved differently from that same ancestor. All apes and monkeys share a more distant relative, which lived about 25 million years ago.
