Hellooooo please help :)


how do countries meet the needs of populations?
Answer with at least 3 sentences.

Answer: China, perhaps more than any other country, faces many important and difficult population challenges: reproductive health and reproductive rights, rural-urban migration and reform of the hukou system, and imbalances in the sex ratio at birth. And two deeply connected population issues, the rapid aging of the population, on the one hand, and the low birth rate and the family planning policy on the other, are of great significance to China's future development.

China's population is aging as rapidly as anywhere in the world and its low birth rate means it faces a significant population decline in the not too distant future. In part, China's population will age because people are living longer, an important dimension of China's great progress. But the country's low birth rate is the most important reason for population aging, leading to a very top-heavy age structure with many elderly, fewer workers, and even fewer children.

The low birth rate and population aging mean China faces two important economic challenges. The first is maintaining economic growth and poverty reduction, while the second is ensuring economic security for hundreds of millions of elderly.

Since the beginning of economic reform in 1978, changes in age structure have been very favorable in China. Because of the decline in the birth rate, only partly a consequence of the family planning policy, the number of children in China has decreased and the proportion of the population that is of working age increased. This led to a demographic dividend in China that provided an important boost to efforts to increase economic growth. Experts disagree about the size of the demographic dividend, but scholar Wang Feng and I believe that it added about 1.3 percentage points to economic growth between 1978 and 2000, smaller than some have argued, but still an enormous effect.

China's first demographic dividend is coming to an end as the size of working age population is peaking and will soon begin a rapid decline. Over the next 40 years, China's support ratio, the effective number of producers per effective consumer, will decline by about 0.4 percent per year. As compared with the dividend phase, this changing age structure of the population could lead to a downward swing in economic growth of 1.7 percentage points per year. That would be a very serious development and a great setback to China's efforts to join the ranks of high-income countries.

A second demographic dividend could be the answer to China's economic growth challenge, but it is far from automatic. First, as countries' birth rates decline they substitute child quality for child quantity. People around the world are having fewer children but they are spending more on each child. In particular, they are spending more on health and education for children. Countries end up with fewer workers, but workers who are healthier, more educated, and more productive. China's recent emphasis on improved human capital investment is an important step toward realizing this second demographic dividend.

hydrothermal, geothermal, and wind

Hydrothermal, taped from the biggest river on the state contributes approximately 60% of the energy in the state. Geothermal is second,approximately 30% while wind power contributes approximately 10%.

The costs of the electricity in the state are relatively cheap compared with states whose main source of energy is hydrocarbon fuels. Geothermal power is the cheapest (even though initial investment is prohibitive). Hydrothermal is slightly expensive than geothermal due to the maintenance required and also is prone to fluctuations of the river regime. Winds are also cheap but initial investment if the wind farm is high.

Hydrothermal energy has the biggest environmental impact compared to the other two. Due to the walls of the dam on the river, migration of some aquatic species is impeded. The reduced flow of water (and sediments) downstream of the dam also impact these ecosystems. Geothermal and wind energy sources have a very minimal environmental impact on the environment .

The state could increase electronics with low power consumption (such as LED lights) in the market for availability to the population. This would be followed by a sensitization campaign on the ideal use of power in the household to conserve power when not in use.

excessive pollutants. Before the land and pond were disturbed by the construction
of the playground, hiking trail, and parking lot, you counted the number of fish in
the pond. At that time, Cypress Pond contained 100 trout and 100 catfish. Now you
need to design an experiment to monitor the park’s impact on the populations of
trout and catfish over the next 12 months.
1. What is the purpose of your experiment?
2. Develop a hypothesis for the experiment.

Monitoring the Biodiversity of Cypress Pond
Procedure
In this section, you will create a step-by-step procedure for testing and monitoring
the number of trout and catfish in Cypress Pond. You must monitor them once per
month for 12 months after the park is built.
Data from Monitoring the Biodiversity of
Cypress Pond
Listed below are the results of your hard work. You monitored the populations of
trout and catfish in Cypress Pond every month for a year after the park was
developed. For each month, add the amount of both types of fish together. Write
this total in the Total Number of Fish column. Present these results by creating a
line graph.

Analysis
1. What is the relationship between biotic and abiotic factors?
2. How did the construction of a parking lot, hiking trail, and playground affect
the fish populations in the pond?Conclusions
1. How would the ecosystem’s carrying capacity for a species change if the
species cannot adapt to changes in its habitat?
2. Why are biologists concerned about ecosystem disruption?
3. If you were conducting this experiment in the real world, what might be
some possible sources of error in the experiment?
