In this area, we must speak of development that meets the needs of the present, but does not jeopardize future generations' own needs and does not threaten the national sovereignty of other countries.

This notion first appeared in the report of the World Commission on Environment and Development: Our Common Future

Rio de Janeiro Declaration on Environment and Development explains the goals of the concept of sustainable development as a whole and a special commission on sustainable development has been established within the UN.

The world population is rising rapidly by approximately 75 million per year. Soon there will be 8 billion by the 2020s. This rapid increase in human numbers puts the world economy and the environment at risk. The reality is poor people have a difficulty finding food, shelter and maintaining their own health. There are so many parents are struggling to create a bright future for their children. Besides that, the environment is getting worse and becoming unattainable for some areas. Humanity is changing earth’s climate, polluting fresh air and having a negative effect on clean water, especially oceans and rivers.

The huge problems as I have mentioned (such as poverty) can be solved by economic development. But the point is developing of economy increasing the environmental threats. Thus, we arrive at sustainable development. Sustainable development consisting of 17 different goals helps us to achieve the economic, environmental and social objectives.

The goals serving environmental objective are clean water and sanitation (6^th goal), affordable and clean energy (7^th goal), responsible consumption and production  (12^th goal), climate action (13^th goal), life below water (14^th goal), life on land (15^th goal).
