There are many explanations for overpopulation worldwide. Firstly, medical advances contributes to overpopulation. Health services are developing day by day, people get better services every day, we get better care and treatment than before. Therefore, People will live healthier and live longer. From there the death rate will decrease. Moreover, scientific inventions in medicine make it easier for people to have children, which will lead to a higher birth rate. Secondly, nowadays, there is no more war in the world so the death rate is decreasing. In the past, hundreds of millions of people died because of the war, especially in world war. Finally, in some parts of the world, people do not have enough knowledge about family planning and birth control, so they tend to have a lot of children in their family.

In some part of the world, people do not have enough knowledge about family planning and birth control, so they tend to have many children. In many countries, sex education and family planning is not paid enough attention. Consequently, the rate of early marriage and unprepared child birth is higher.

There are several effects of overpopulation. Firstly, the more people live on the Earth, the more the environment is impacted. When too many people live at the same time, the amount of land and resources, which is limited, will be used more for our life. It leads to exhausted resources. As a result, people may face lack of food and water…(đây là ý khác ko phải ý môi trường) Moreover, population explosion means that more emissionS from vehicles, factories is emitted, causing pollution, global warming or natural disasters. Secondly, overpopulation is a contributing factor to reducing quality of life. People not only suffer from environmental pollution but also suffer from noise pollution which has negative effect on mental health when population density is higher. In addition, it is be difficult for the Government managing ^{to manage} security and welfare when overpopulation happens. Finally, overpopulation is the cause of the rising unemployment rate. There are not many^enough job opportunities for everyone. Moreover, machines are gradually replacing humans in many tasks. So, in the future, if overpopulation occurs and no measures to prevent it, there will be a high rate of unemployment.

There are several causes of overpopulation. Firstly, nowadays the world is stable and peaceful, there number of people who died because of war is decreasing while the quality of life is rising. Therefor, more people tend to get married and have children, the results is the birth rate is more increasing. Secondly, advances in medical give people more opportunities to get medical care. Nowadays, people have found many types of vaccines and new methods to cure. Many diseases which in the past can't be treated but now have been cured by scientists. This leads to a fall in the death rate and a longer life expectancy. Finally, in some countries people still have the belief that having many children is a blessing so they tend too have as many children as possible.

There are several effects of overpopulation. Firstly, environmental pollution is the most affected area(En pollution can result from population explosion/En pollution is one consequence of overpopulation) . When the population on the Earth increases, people need more land for living and work(building houses, doing farming and building factories) so they expand the area???) by burning forests and destroying forests to make workspaces (to take land). This leads to (worsens air pollution and global warming ~~in the world~~. In addition, domestic (industrial) emissions(?) are often not treated and reach streams, rivers and oceans, which causes water pollution. Secondly, overpopulation causes social problems. There are too many people so there is not enough work for all, which leads to the high rate of unemployment around the world. Moreover, a place where there is a high rate of unemployment, usually has a high crime rate too. Finally, the quality of life of people living in metropolitan areas is reduced. They always feel uncomfortable because of air pollution from transports, factories.., some of them face a lack of clean water... (viết tiếp: slum, lack access to education and healthcare)

There are several causes of overpopulation. Firstly, the population increase because of medical advances. Developed medical services help life expectancy increase. Many serious diseases have been prevented because medical science invented many kinds of medicines. So the elder can live longer. Secondly, a time of stability and peace leads to decreasing death rate. In the past, many people died because of war. Hundreds of millions of people died, especially in world war. But after the world war, fewer people die. As a result, the married rate grows and many children are born. Finally, in some parts of the world, especially developing countries, people do not have enough knowledge about family planning and birth control. In poor countries, a family often has many children to maintain the family line. Besides, some young people do not have knowledge about sex education. It leads to having unplanned children very early.

Cause:
There are several causes of overpopulation. The first reason is advances in the medical field. More and more vaccines, penicillin, antiviral drugs,... have been developed to help cure fatal diseases, control epidemics. Thus, the rate of fatality and prolongs human life expectancy reduces. The second reason is a time of peace and stability. It is true that there are no wars in most parts of the world today. As a result, fewer people die because of war, contributing to a decline in the death rate. Another reason is the lack of access to education. In some parts of the world, sex education is rarely offered in schools. Therefore, people have little or no knowledge about family planning and birth control methods, leading to leading to many children being born

There are several causes of overpopulation. Medical advance is one of the reasons that contribute to overpopulation. In the past, medical technology hasn’t developed yet, the number of people who die from fatal disease is very high. However, the development of medicine allows us TO find and come up with many treatments. Therefore, death rate decreases and people live longer. Another reason for overpopulation is the lack of education. People aren’t taught about sex education, especially in rural areas. They don’t know about birth control and family planning. This is one of the reasons for the high birth rate. The last reason is that We live in peace and stability for a long time. It means we don’t have to die on battlefield. Before the worldwide II, people’s life expectancy only reached about 40-50 years. From after the worldwide II to present, people’s life expectancy can reach about 70-80 years. It also leads to overpopulation.

There are many cause of overpopulation. Firstly, development science especially medical science. Today, medical science is more advanced than in the past. For example, many kinds of vaccines and antibiotics are created so they help people reduce death rate when people get diseased. Besides, today the medical industry also has many health care services and healthy products to help people live helthier. So, people live better, they live longer and the death rate decreases. Secondly, there are not as many wars today as in the past. One of the reason why so many people died in the past was war. For example, during WW2, 85 million people died in this war. Howerver, today most of country dont want war, so the world is at peace. Thus, a decrease in the number of deaths from war means that the death rate is lower than in the past.

there are several causes of overpopulation. the first reason of overpopulation is medical advances. science and technology are developing day bay day, vaccines, antibiotics and other modern treatment are invented, and constantly advanced. thank to that, many disease are prevented and cured lead to people live longer. Secondly, overpopulation is the result of belief in some areas. Many people say that having many children will create a lot of labor for families, most of which come from the agricultural areas. besides, some people beliefs that family must have a son. therefor, although having a lot of daughters, some parents continue to having a son.

there are several effects of overpopulation. firstly, when population explosion^explodes, natural resources will be reduced. because of overusing them for people needs, such as coal to make fuel, land for farming and living while ~~they just has~~ there is only a certain amount of them in the nature. (câu quá dài không viết câu dài thế này em nhé, có rất nhiều vế--> tách ra 2 câu) if we don't reasonable use them ^{use them reasonably}, they will run out soon. secondly, overpopulation is contributing factor to pollution. population explosion means that more trees are cut down, more vehicles are used, more factories if founded to serve more people. As a result, having a lot of emission impact on environment, make the pollution. (chưa rõ nghĩa)(em nên viết: nhiều khí thải gây ra ôi nhiễm, rồi Global Warming..)

overpopulation nowaday is becoming quite a serious problem, these are some main reason for that. firstly, the development of medical condition (medical field) lead to the decreasing of death rate. human now is able to cure almost every disease that we couldn't cure in the past, and so do preventing many diseases. the number of people who died from diseases IS now smaller than in the past. secondly, a time of peace in most parts of the world make the number of people who died by war decrease, people are likely to get married and so that grow the birth rate dramatically (birth rate grows) the last reason, but also important that in some countries, IS THAT people still prefer son rather than daughter, then they keep giving birth until they have a son. this is an outcome for lacking knowledge of family planning.(bỏ)

There are several causes of overpopulation. Firstly, the world is developing more and more which means we have more medical advances. We have create vaccines, antibiotics, and other modern treatments that can cure diseases and prevent diseases so humans have longer life expectancy. Another reason for overpopulation is beliefs. In many countries, people still have the belief that having a son or having many children is a blessing. The fact that not everyone can fulfill their wish in the first time, so the women have to give birth until a son is born, and until the family have about three or four children to stop having children.

There are several causes of overpopulation. The first reason for the population explosion is medical advanceS. Medicine is increasingly evolving as (bỏ) researchers have created many types of vaccines and antibiotics that were not available before. Modern treatment methods have been widely applied so the patient was cured to prevent diseases. people have lived longer, the world's average life expectancy has also increased. The second reason is that during a time of peace in most parts of the world, fewer people die because of the war like in the past so the death rate decreases. a time of peace and stability, people will get married and have more children.

Effects
Overpopulation affects the environment and society ^{has several consequences}. The first consequence for the that is it causes environmental problems. A rise in population leads to more emissions from vehicles and factories, people cutting trees, clearing forests to make land for housing, building factories. Those things will put pressure on the earth, the effects of global warming will cause sea levels to rise, every year there are record-breaking storms that cause a lot of damage.(Chỗ này em cần nói từ từ: những việc như trên sẽ làm tăng pollution, gây ra Global Warming, Climate Change rồi disasters...) Second, it affects the society. When the population explosion occurs, the Society will increase the (there will be higher demands for )demand for jobs, causing unemployment, underemployment, low living standards. people with low living standards will live in slums, lack of education and health care for the elderly and children, creating more social evils.(cấu trúc ngữ pháp, chỗ này lack of... đi với cấu trúc gì?

Causes
There are several causes of overpopulation. Firstly, the reason for the population explosion is medical advances. People are creating more vaccines, antibiotics, modern treatment methods to cure diseases that couldn’t be treated in the past such as cancer, white blood,… and prevent diseases again or reduce it slowly (bỏ) . Secondly, nowadays we are having a time of peace in most parts of the world. Fewer people die because of the war like its used to in the past so the death rate decrease, life more stable and the average life expectancy is increasing, people will tend to marries and get birth. Finally, there is a lack of education in some parts of the world. Especially in developing countries and poor countries, where people do not have any knowledge about family planning and often have many children as possible to maintain the family line
Effects
There are several effects of overpopulation. Firstly, a rapidly growing population leads to a shortage of environmental resources (cần giải thích ý này chứ không chỉ đưa ra để đấy). Emission from vehicles and factories directly affects air pollution and the ozone layer. Waste from humans and industry leads to soil and habitat pollution degrades ecosystems and climate change (đã liên quan đến overpopulation chưa hay chỉ là hoạt động con người nói chung?--> chỗ này cần nói từ overpopulation, dân đông nên làm sao làm sao...) . Secondly, too many people mean not enough places to live, people have to cut down forests to have a place to live, which leading ^{which leads/leading} to landslide erosion and wildlife habitat impact (hơi trùng với ý trên). Finally, in overpopulation countries, too many people mean the chance of getting a job is reduced and the rate of unemployment will increase rapidly. As a result, the crime rate increasing as thieves, rob.

There are several effects of overpopulation. It is only logical that an increase in the world’s population will cause additional strains on resources. More people means an increased demand for food, water, housing, energy, healthcare, transportation, and more. And all that consumption (all of those demands) contributes to ecological degradation. An increase in population will inevitably create pressures leading to more deforestation to take land for housing and working, decreased biodiversity, and spikes in pollution and emissions from vehicles or factories, which will exacerbate climate change and global warming (câu này quá dài, phải tách và lại nói ý mới không liên quan đến ý resources: ý resources cạn kiệt là một ý, môi trường bị ôi nhiễm là một ý). The second of these is the depletion of resources. The Earth can only produce a limited amount of water and food, which is falling short of the current needs.^{(trùng ý trên)}Even human beings are destroying nature for their economic purposes. Finally, when a country becomes overpopulated, it will rise to unemployment as there are fewer ^{not enough} jobs to afford for a large number of people. ~~As a result,~~ the crime rate may also increase because of unemployment.

There are several effects of overpopulation. Firstly, the world population is increasing day by day which means more and more food is consumed. However, the Earth can only produce a limited amount of water and food, which is currently short of current needs. At some point in the future, we will face resources exhausted (nếu em nói chung về resources thì nên chú ý support liên quan đến resources. Ở trước mới chỉ có food thì chưa đủ bao gồm resources). Secondly, Research shows that much of the environmental damage is due to the increasing number of people on the planet. Overpopulation means more and more trees are being cut down to make way for land for housing, agriculture and factories. This causes climate change and global warming. They (chưa rõ they là gì) have a negative impact on human life. Second, when a country becomes overpopulated, it leads to unemployment because there are fewer^{(not enough)} jobs to support a large number of people. The rising unemployment rate also gives rise to crimes, such as theft, murder, … making society worse and worse.

Effects:
There are several effects of overpopulation. Firstly, overpopulation can have adverse impacts on the environment. As the population rises, there is an overuse of coal, oil and natural gas, which are nonrenewable, leading to the quicker depletion of natural resources ~~quicker~~. Moreover, population explosion can pose a serious threat to the world’s wildlife. The destruction of natural habitats, such as chopping down forests, becomes common to take land for houses, farms and factories. Therefore, many of the world’s wildlife species will be put on the edge of extinction, which interrupts the food chain and creates a decrease in biodiversity. Secondly, overpopulation has some damaging consequences on society. When a country becomes overpopulated, there will be a higher unemployment rate as there are fewer jobs to support the growing population^{(as there would not be enough job position for the growing number of people)}. Moreover, low-skilled workers can be out of work if they cannot compete with high-skilled job seekers in the market. In addition, high densities of population results in a higher risk of disasters and pandemics. For instance, the high population places often have a high rate of people infected Covid-19.

As a result, the number of unemployed people also increases.

Effects

There are several effects of overpopulation. To start with, growing human populations rapidly can lead to pollution. There are more industrial sites to meet employee demands. Industrial waste will be more and more, contributing to air pollution. Besides, population explosion means that people don't have places^{(have little space to live)} to live. For this reason, humans destroy forests to take land for living and farming. This leads to global warming, and climate change. Secondly, population booms are driving the running out (?)(ok nhé) of natural resources. Demand for energy is increasing rapidly, because of the growing population. Humans are highly exploiting resources. Finally, overpopulation causes unemployment rates to increase. In big population (populous) areas, they can’t get the opportunity to work because the job competition rate in that country is high ^{(cần giải thích rõ ý này hơn: nhiều người hơn, lượng công việc vẫn vậy (high job competition rate) -> more people being jobless)}. Moreover, the lack of jobs leads to increased crime rate …^{(cần giải thích thêm)}

Causes

There are several causes of overpopulation. The first reason for the population explosion is a time of peace in most parts of the world. In the past, there were many people who died because of the war. However, nowadays, there is no war so the death rate decreases. When life stabilizes, people are more likely to get married and have many children. Secondly, thanks to medical advances, vaccines, antibiotics, and other modern treatments have been developed day by day. , serious diseases may be cured and people can prevent diseases. People may be living longer than before. Moreover, people can take better care of themselves. This helps the world's average life expectancy increase. Finally, there is a lack of education in some parts of the world. Communicating family planning and birth control methods is limited. They have little or no knowledge about family planning, so they tend to have many children. As a result, the birth rates are growing rapidly in these countries.

There are several effects of overpopulation. First of all, it requires too many resources to support the population, so the government can not help all the people , leading to the gap between rich and poor. Secondly, overpopulation also makes (causes/worsens) environmental pollution. The increase of people living in one place means the increase of vehicles, factories with ~~that~~ emission coming from both these things contribute to global warming. Besides, it also leads to deforestation when people cutting down too many trees to take land for housing, farming, factories. Finally, another drawback of overpopulation is the high rate of unemployment, the more people we have, the lower the chances of getting a job.

there are some effects of over population. Firstly, overpopulation is the cause of environmental pollution, especially air pollution. Overpopulation will cause the number of vehicles to increase. It means emissions into the environment have increased ^{(increase - dùng hiện tại đơn thôi)} compared to the past. Besides, overpopulation will make the population too large and people will have to deforest to build cities. Earth without trees will become a dead planet because humans and animals will have no oxygen to breathe (chỗ này nói rằng vấn đề sẽ trầm trọng hơn, worsen pollution, contributing to Global Warming and Climate Change). Secondly, Overpopulation will make many people unemployed. nowadays, many modern machines have been produced which make people have fewer jobs. So if the population is too large, the unemployment rate will be even higher and higher

in the near future, overpopulation will be a very big problem , and it will bring a lot of troubles. firstly, when the world becomes so populous, there will be problems with ~~jobless~~^{(the source of labor)}, . Limited job opportunities but too many people may raise unemployed rate. secondly, too many people ~~that~~ demands more product and food for us that the earth's resources can't afford, if we keep increasing using it, our planet will run out of resources oneday soon. lastly, many people lead to many vehicle
