In many recent years, the difference between the developed, developing and underdeveloped country tends to increase dramatically. To discuss about this problem, there are a number of reasons why. In my opinion, there are three main causes and three solutions respectively.
First of all, although the world is living in peace these days, some countries still face wars and terrorism. The unstablity makes people injured and homeless. Its effects are the lack of food, water, the destruction on buildings, landcrops,... All those cause poor economy to the nations. To solve this difficulty, the government should avoid unnescessary wars, promulgate serious laws about terrorism, and also improve the national defence. Peace should be recommended highlier in order to guaranteed the citizen's happiness.
Secondly, education is extremely essential in every countries. In poor nations, people often do not pay much attention to this. For instance, in recent years, India has approximately 47 millions children who do not go to school, which means that a half of Indian children are illiterate. Meanwhile, some countries like Neitherland, Finland, Australia promote the educational policies years by years. The illiteration causes variety of serious problems related to the national development. Therefore, the authorities should have some solutions. They can organise free classes for poor students, encourage volunteer teahcers, give books to children,.... When education has a steady place, the society can develop more than ever.
Last but not least, population is a key to a nation's success. As the development of the world, the population increases everyday, especially in poor nations. We can take Vietnam as an example, in 2021, its population is 98 millions and the land area is approximately 360,000 square kilometres, which means that about 317 people live in 1 square kilometres. Large population affects much on the economy. Facing this problems, we should have family planning, comply the population policies in order to encourage the country's development.
In conclusion, the peace, education and population are three main factors which can change the poverty. If any countries conceives this, they can gradually become a developed nation, and the gap will be narrowed soon.
