Population growth is the increase in the number of human beings on earth. In most parts of human history the volume of our population was relatively stable. But with industrialization, energy, food, water, and medical care became more available and reliable. As a result, the global human population has increased rapidly, and this continues with a dramatic impact on global climate and ecosystem. We need technical and social innovation to help the population of the world because we adopt and reduce climate and climate change.

The world's population was over 7.3 billion in 2015. These are more than seven billion three hundred million bodies that need feeding, dressing, keeping warm and, ideally, nurturing and educating. More than 7.3 billion people who are busy using resources, are also generating large amounts of waste, and our Numbers are constantly increasing. The United Nations estimates that the world's population will reach 9.2 billion by 2050.

The use of resources and the effects of environmental problems are not equal all over the world. People of developed countries need more resources to maintain their lifestyle than people of developing countries. For example, the United States, which comprises 5% of the world's population, currently generates a full 25% of CO2 emissions.

People in developing countries feel the effects of environmental problems more intensely, especially if they live in coastal areas affected by direct sea-level rise and extreme weather events with climate change. The most vulnerable populations also face reduced access to clean water, increased exposure to air pollution and diseases - which can result in a decline in biodiversity - and local resources, including plants and animals, can feel an immediate impact on the extinction of.

While population growth and the interrelated problems of environmental problems are seen very much, it is important to remember that humans can make changes that have a positive impact on the planet. A good starting point is to understand and implement the concept of sustainability, which is contrary to the lack of resources. Sustainability defines a model of resource use in which the current generation USES only the resources that the earth provides indefinitely (such as solar or wind power instead of burning fossil fuels) for the resources.

How to Minimize its Adverse Effect

Ensuring that every child gets quality education is one of the most effective measures for sustainable development. Many children in developing countries are out of school, with more girls than boys affected by gender inequality. Education opens the door and provides a "way out" to disadvantaged children and youth. How many years a woman spends in education and how many children she has born are directly related.

Educating only men and women about contraceptives can have a big impact. When Iran introduced a national family planning program in 1989, its birth rate was reduced from 5.6 per woman to 2.6 in a decade. A similar effort in Rwanda saw a threefold increase in the use of contraceptives in just five years.

The problem of underage marriage is very prominent in some countries with high populations like India, Pakistan or Bangladesh. Early marriage takes a long time to give birth to a child. Apart from this, early marriage deprives people of education and awareness that they need to be sensitive and understand the consequences of raising too many children.
