Who constructed a theory that focused on population size?

1 answer:

4 0

According to Malthusian theory of population, population increases in a geometrical ratio, whereas food supply increases in an arithmetic ratio. This disharmony would lead to widespread poverty and starvation, which would only be checked by natural occurrences such as disease, high infant mortality, famine, war or moral restraint. His main contribution is in the agricultural sector. According to this theory there are two steps to control the population: preventative and positive checks. Preventative means control in birth rate, and uses of different methods to control birth; and positive checks means natural calamities, war, etc. His theory was wrong because Malthus only considered two factors when he established his basic graph: food supply and population growth. Other factors such as improvements in technology proved him wrong. He was right at his time but development made him wrong. If it wasn't for outside influences on population growth and food supply, his mathematical reasoning which proved his theory and was right. I HOPED THIS HELPED

Technological improvements and reduced equipment costs have made converting solar energy directly into electricity far more cost

Natali [406]

Hello. This question is incomplete. The full question is:

"Technological improvements and reduced equipment costs have made converting solar energy directly into electricity far more cost-efficient in the last decade. However, the threshold of economic viability for solar power (that is, the price per barrel to which oil would have to rise in order for new solar power plants to be more economical than new oil-fired power plants) is unchanged at thirty-five dollars. Which of the following, if true, does most to help explain why the increased cost-efficiency of solar power has not decreased its threshold of economic viability?

(A) The cost of oil has fallen dramatically. (B) The reduction in the cost of solar-power equipment has occurred despite increased raw material costs for that equipment. (C) Technological changes have increased the efficiency of oil-fired power plants. (D) Most electricity is generated by coal-fired or nuclear, rather than oil-fired, power plants. (E) When the price of oil increases, reserves of oil not previously worth exploiting become economically viable."

Answer:

Explanation:

Economic viability is able to reveal the degree of acceptance of consumers in relation to a specific product. This viability is important to understand how the product will be received in the market and how profitable or not it can be for those who produce it.

Economic viability is usually greater when the cost and benefit ratio of the product or service is favorable, however this is not always the case.

Regarding the use of solar energy, although technological changes have made the installation and equipment of this type of energy more cost-effective, these technological changes have also increased the efficiency of oil plants. As a result, the economic viability of solar energy has declined.

Ethnicity

Ethnicity is a social group that shares the same culture, language , ancestry or religion. Ghana is a multi-ethnic society. it has a diversify ethnic groups. The Akan ethnic groups are the most numerous ethnic group . Other ethnic groups are the Ewe, Ga, Gonja, Dagomba, Guan, Kyerepong etc. Understanding and respecting the ethnic diversity of the Ghanaian population is a good step in uniting the society.

Religious belief

The major religion in Ghana are Christian , Muslim and the traditional religion. Understanding the spiritual affiliation of the Ghana society is a good rallying point to unite all Ghana. The government needs to adopt policy that will benefit and align with the spiritual practice of the Ghana community.

Educational Background

Education plays a major role in the society. An educated society improve standard of living , improve cohesion among the populace and also encourage brotherhood. The Ghanaian population have a tiny group of people that had the opportunity to attend higher institution . The educational disparity among the populace is a major factor to adopt in order to unite all Ghanaian society.

History

History means studying the past - specifically the people affairs, events and problems. If one does not consider the history of a society especially if the history of the society was a problematic one , they are likely condemned to repeat it. Therefore the history of the people is a major factor to adopt in order to unite a society. Moreover, Ghana have had major history of war among ethnic groups and this is something the government won't love to ignore.

Other factors to adopt in order to unite Ghanaian are demography , political stance of the people.
