Last July, 1 1 was the 6th World Population Day. The United Nations Population Fund takes "Equality = Empowerment" as the theme of this year's World Population Day, emphasizing gender equality and giving girls and women equal rights. At the same time, it also proposed four important areas for action, including education, economic opportunities, reproductive health and rights, and political participation. In July 1987+0 1 day, the world population reached 5 billion. In order to arouse the international community's deeper concern about the population problem, the United Nations Population Fund designated July 1 1 as "World Population Day" in June 1990, and requested governments and non-governmental organizations to carry out related activities during this period. According to the statistics released by the annual World Population Conference at the end of June, as of June 2005, the world population has reached 6.477 billion. It is estimated that the world population will reach 9 billion to 654.38+0 billion by the middle of this century. Due to the uneven global population distribution and the rapid population growth in developing countries that have not yet achieved food and clothing, the current population situation has posed a serious threat to human society. At present, there are still 1 billion people living below the poverty line in the world. With the rapid growth of population, the world still has a long way to go to achieve the goal of halving the poverty population by the end of 20 15. Facing the increasingly severe population situation, development has become the basis for solving the population problem. When the development problem is solved, the population problem will naturally be solved. To solve the population problem, we must first base ourselves on economic development and establish a new mechanism for rational allocation of global resources. At present, the population growth in underdeveloped areas is too fast, and the current distribution mechanism of earth resources only benefits a few developed countries.
