Review of problems for a population growth essay

Since the population is a social institution, it is important to highlight the problems that have prompted positive changes in the population in the last 50 years. The current size of the population, exceeding 7 billion, is too large. And the consequences are felt by the whole planet: the oceans and seas are devastated, all large areas of the earth suffer from mining and agriculture, the tropical forests and other ecologically important wild areas decrease catastrophically. Fields for cattle, areas for food and energy plants, as well as zones for planting fruit and other trees arise in their place.

For this reason, it is worthwhile to seriously think about reducing population. But it is not about radical measures infringing on human rights. The world community should resort to a reasonable limitation of population growth rates, as well as to encouraging spatial distribution of people.

Writing an essay on the ecological effects of increased population, you may describe the picture of the future world. The following features characterize a society that, in its development, goes beyond permissible limits, uses Earth reserves faster than they can be restored, is freed from production waste polluting the environment faster than the planet can absorb or recycle these wastes:

READ:  What is the analysis of the situation by the policemen and gi prisoners. By this time, both sides are familiar with the procedure of summary execution, rigorous interrogation and imprisonment. The regular practice is the simultaneous application of various psychological means (hacking, punching or shooting). A prisoner is squeezed out of the cell. The abdominal cavity is opened with one motion of the knife, and the heart is pulled out. The corpse is thrown into the fire.
  • the situation in the field of renewable resources deteriorates: a reduction in the supply of water, wood, fish, reduced soil fertility;
  • waste products accumulate and increasingly pollute the environment;
  • more and more investments, energy, materials, labor costs are needed for research, development, and operation of hard-to-reach sources of raw materials;
  • more investment, energy, materials, and labor costs are required to eliminate the negative consequences of using free resources: for sewage treatment, irrigation control, air purification, etc.;
  • a significant part of the capital, raw materials, and energy resources, labor costs are spent on solving the tasks of the defense industry;
  • the situation deteriorates in such long-term state programs as road construction, education system, culture, etc.;
  • investments in human resources decline, the situation with education and health deteriorates;
  • the balance between the use of raw materials, energy resources and the process of environmental pollution is disturbed;
  • there is less mutual understanding, more and more obstacles and discrepancies in the solution of these problems.
  • Thus, it becomes obvious that the Earth can withstand a much larger population than at the moment, but its existence will be accompanied by an irreversible oppression of the environment, a decrease in the total amount of resources. As a consequence, there will be a decrease in the comfort of living of each person on the planet in conditions of crowding, psychological and physical discomfort.

    When you’ll finish the research on population, conclusion (essay last paragraph) should lead the reader to the following idea: in order to prevent such phenomena, it is necessary to work out a set of measures (including various directions from the demographic to new energy policy) for implementation by the entire international community.

    READ:  What is something like food for the brain. Studies on human sexuality are focusing on the brain, nervous system, kidneys, digestive system, hepatus, nigra, and placentry. The brain is particularly important for the formation of sexuality. Therefore, the study of sexual activities in the laboratory and clinical studies is of great importance. In addition to these types, scientists are studying other areas of sexuality, including sex, pregnancy, and lactation.

    Problem of population aging

    Aging population argumentative essay topics are quite relevant today, because according to the UN, during 1994-2014, the number of people over 60 years has doubled. In 2014, the number of old people in the world exceeded the number of children under the age of five.

    In some countries, for example, in France and Sweden, the first signs of a population aging have emerged in the last century. But never before the increase in the number of old people has occurred with such pace and scale as today.

    Now, in 15 EU countries, above 15% of citizens are at the age of 65 years and higher. The youngest country is Ireland (11.5%), and the oldest one is Sweden (17.5%). However, during the coming decades, the gap will decrease. The elderly group will be supplemented by generations born during the last baby boom (1946-1964). Compared to Western European countries, the United States is a younger state: there are less than 13% of people over 65 years old.

    The causes of population aging are ambiguous. On the one hand, this is the decline in the birth rate, which leads to a reduction in the number of children and young people, on the other – an increase in life expectancy. In 1996, the average life expectancy in the EU was 80 years for women and 74 years for men. Sweden had the highest indicator, Portugal – the lowest.
