Final answer:
Sustainability is a key trend affecting how and what people eat, necessitating a shift towards more sustainable food systems that take into account health, environment, and cultural impacts.
Step-by-step explanation:
One current economic and social trend that is poised to significantly influence how or what people eat is sustainability. Emphasizing the need for sustainable food systems is essential for ensuring a healthy future with minimal environmental impact. These systems must address not only world hunger but also encompass broader concerns such as health and welfare, efficient land use, maintaining water quality and availability, reducing energy consumption and production, minimizing greenhouse gas emissions and mediating climate change, as well as considering the economic, cultural, and social values globally, nationally, and within local communities. Additionally, sociological perspectives highlight that food consumption is also shaped by cultural habits and is at the crossroads of social movements, political issues, and economic debates, potentially leading to key changes in our food system including the adoption of sustainable farming practices and an increased focus on local production and distribution (locavores).
