This year's World Environment Day slogan is "Seven billion dreams. One planet. Consume in moderation". development This year, the United Nations Environment Programme (UNEP) through the Goodwill Ambassadors have formed a Dream Team to ask the global community to share their dreams of a more sustainable future and commit to making the Sustainable Development Goals a reality, focusing especially on what we consume and waste most at the same time: water, food, energy and all natural resources.

In September 2015, the result of the negotiations on the seventeen goals for sustainable development currently under discussion among the member states of the United Nations, which will set the pace of the international diary in the next fifteen years for a better and fairer world, will be announced. These seventeen goals were proposed by the group of experts, following numerous meetings involving UN agencies, governmental institutions, civil society organizations and representatives of private entities.

Food waste
I am going to refer to the reduction of food waste as one of the priority objectives to be taken into account in the coming years in order to reduce hunger in the world. The amount of food that is wasted and lost worldwide is scandalous. Worldwide, between one-third and one-quarter of food production for human consumption is lost or wasted, according to estimates by the Food and Agriculture Organization of the United Nations (FAO) and high school of World Resources. Food is wasted at every stage of the food chain from farmer to consumer, producers, processors, retailers, supermarkets, caterers and consumers.

Action must be taken against food waste through a set of measures such as improved labeling -preferential consumption date and expiry date-, innovation in packaging that can reduce waste and its environmental impact, by improving the materials and characteristics of design, such as reusable airtight containers and the development of intelligent films that indicate the loss of freshness through a change of color, and of course the distribution of food among disadvantaged people and groups, leaving disposal and industrial recycling as the last measures. Many countries in Europe, such as Austria, Spain, Denmark, Italy and the United Kingdom, have effective food bank programs, in which surplus food is transported from families, retailers and wholesalers to people and institutions in need.
