A country has a lengthening life expectancy and a declining birth rate. Which of the following solutions might it need to implem
ent in the future to solve its demographic problems? I. Subsidized family planning II. Raising the retirement age III. Paid maternity leave IV.Building more schools (3 points) I and III I and IV II and III III only
The answer is III, raising retirement age and building more schools will not affect this situation very much, while paid maternity leave will help raise the birth rate.
For a country in order to increase the population by increasing the life expectancy and increase the birth rates needs o implement programs that provide more time for the families to raise their kids and so that the country has younger population in the future and increase the health and medical facilities so that demographic problems can be solves in the future. Maternal leaves allow the family to take care of the child, like china.
The Earth is a "closed system" which means that the amount of rocks, carbon, metals, nitrogen, water and oxygen on earth remains constant.
So it is essential that "biogeochemical cycles renew these materials" as they move through the Earth's subsystems.
<u>Explanation</u>:
The Earth's only source of extra-planetary energy is the Solar radiations received by Earth.
The biogeochemical cycles on the planet are responsible for processing the same old rocks, metals, carbon, nitrogen, oxygen, water, and other abiotic substances on Earth in order to naturally renew them and make them available for reuse.
No naturally occurring element on Earth is newly produced. It is only renewed through biogeochemical processes.
