The concept of the circular economy (CE) represents a development model that aims to mitigate the negative impacts of human actions through the implementation of the basic principles of the '3Rs': reduce, reuse and recycle, with the goal of constantly maintaining the highest degree of utility and value for products, components and materials. The basic principle, therefore, of the circular economy is the creation of economic value for those products that until now have been regarded as industry waste.
Food systems consist of all the actors and activities involved in the production, aggregation, processing, distribution, consumption, and disposal of food products originating from agriculture, forestry, fisheries, food industries, and the economic, societal, social, and natural sectors involved.The concept described above emphasizes the scale and complexity of these systems, which involve the entire food chain and are central to human needs. However, while it is intuitive to consider food systems as essential for human life, it is less immediate to identify the interdependence between climate and food systems.
Cultured meat (or "cultured meat") is a type of meat that is produced through the methodology known as "cellular agriculture." Cellular agriculture aims to produce food, including meat, fish and dairy products, from the cultivation of stem cells. The first key difference from conventional meat production is that cultured meat does not require animal farming. In fact, the main innovation of cultured meat is that it is not strictly necessary to grow one or more animals to obtain meat, but that it is possible to grow cells to obtain only the tissues needed for food.
Data from reports on global sanitation reveal the presence of an alarming disparity in access to clean water or water resources in general, with deleterious consequences for the health of many of the world's populations. Indeed, the United Nations has come together to discuss and implement change and safeguards with respect to water scarcity. The global water crisis is accompanied by a modest misuse of water for industrial reasons, along with a lack of awareness at the societal level of this problem. Likewise, the heavily affected populations also and especially suffer at the psychological level from this crisis, which is also associated with other effects of climate change. It is therefore considered important to address the psychological distress associated with the difficulties of obtaining clean water, as well as to ensure a more egalitarian and just distribution of resources for all countries of the world.
