Sveta_85 [38]

Answer: Ultimately, a beach erodes because the supply of sand to the beach can not keep up with the loss of sand to the sea. Most sand is transported from inland via rivers and streams. The damming of most waterways in the US has thus prevented a major supply of sand from getting to our beaches.

If you were to look at the age structure of a population of an endangered species and determine that there are mostly older individuals you could say that the population is declining and could be in danger of extinction.

<h3>What are endangered species?</h3>

An organism that faces extinction is referred to as an endangered species. The two main factors that cause a species to become endangered are habitat loss and genetic diversity loss.

Because it prevents our native fish, plants, and other animals from going extinct, the Endangered Species Act is crucial. There is no turning back once they are gone they are lost forever.

Endangered species are those that are at risk of going extinct and must therefore be safeguarded and conserved. Extinct species are those that no longer exist on the planet.

It's Important to Save Endangered Species because:

From antibiotics to anti-cancer medications, they are the sources of those substances.
They are the earliest indication of significant environmental problems.
They support the well-being of crops (and, indirectly, people).
They help the economy grow.
