By 2050, the world population is expected to reach 9.6 billion people, and that means that the equivalent of almost three planets could be needed to provide the natural resources necessary to maintain current lifestyles.

Natural resources are those elements of nature that human beings use to cover certain needs that guarantee their well-being or development. For example: water, trees, minerals, fish, air, oil, etc.

The SDG 12 "Responsible production and consumption" proposed by the UN calls governments, companies and all citizens to work together to improve resource efficiency, reduce waste and pollution, and shape a new circular economy.

Responsible consumption (RC) is based on the 'Rs' rules of sustainability: Reduce, Reuse, Recycle, Recover, etc., as well as on the choosing of quality items respectful to the natural and social environment.
