Until recently, birth rates and mortality rates were the same, keeping the population stable. Man has many children, but a large number die before age five. In the Industrial Revolution, a period of history in Europe and North America, where science and technology progress, success in reducing mortality is due to antibiotics), along with improving the quality of education and living standards in many developing countries.
Without these attributes present in the lives of many children, they cannot survive. Common diseases like measles or influenza. People were able to fight and cure the deadly germs that killed them. In addition, because of this technology, people can produce more food. Gradually, these discoveries and innovations spread throughout the world, reducing mortality and improving the quality of life for most people.
Distribution of food production
The notable events of the past 150 years are the ability of farmers to increase food production in some places. Agricultural activities have improved in the United States over the last two centuries. The majority of the world has experienced agricultural success, especially in the last 50 years. For example, between 1950 and 1984, the amount of cereals harvested worldwide increased from 631 million tons to 1.65 billion tons. This is an increase of 2.6 times while the world population increased only 1.9 times.
In recent years, this technology has created a variety of technologies: new seeds, chemical fertilizers, pesticides and more sophisticated machines. The use of technology has made the rapid expansion of cultural agriculture in the United States and other MDCs and LDCs. The use of pesticides in less developed countries, for example, is expected to increase from 400 to 600 percent in the last 25 years of the twentieth century.
In the past 10 years, world food production has increased by 24%, far exceeding population growth. However, this increase is uneven across the world. In Africa, for example, food has declined, while population has grown. And according to FAO, FAO predicts food shortages in 20 countries in 1994. However, most experts agree that there is no shortage of food, and that fair distribution must be sufficient to meet all future needs. Lack of food is a problem of malnutrition.
Poverty is effectively replacing the world into national and local deficits. In families, men and boys are given priority to whatever food is available, while women and children, especially girls, are the first to experience malnutrition. There are less resources available to women, although they are often responsible for providing food.
Improve public health
People are concerned about their daily lives, such as meeting basic needs: food, water, and housing. First, access to safe drinking water is linked to the incidence of epidemics such as cholera and survival of children. Less than 50% of the population had access to safe drinking water before 1990. By 1990, safe drinking water had risen by 75%. But between 1990 and 2000 the number of people without clean water increased. More and more developed and developing countries are moving towards sustainable water use restrictions based on their own renewable resources.
Second, the pressure to provide adequate housing increases as the population increases. More than half of the developing world population will live in urban areas by the end of this century. This growth far exceeds the ability to provide housing and services to others. In some countries, finding a place to live is very difficult, especially for women. Some women and children are forced to live in the poorest communities where they are open to exploitation and abuse.16Priorities for getting out of poverty, improving food supply, stopping malnutrition, and providing adequate housing at all points with demand for balanced population growth.
Conquest of Disease
The biggest population story in 100 years has been the conquest of disease. Scientists have learned a great deal about the prevention and treatment of many diseases. Thus, millions of people have died from illness a century ago that is more likely to live to an older age. The most effective tools in identifying illnesses have been improved nutrition knowledge, immunization, community health care and the development of new drugs17.In the late 1980s, a child born in Iceland was able to live up to the age of 32.
