Final answer:
The quote from Equal Exchange is described as a mission statement, aiming to outline the organization's objectives and commitment to sustainable food practices and reforming the global food system.
Step-by-step explanation:
The quote “... to change the way food is grown, bought, and sold around the world.” from Equal Exchange is best described as a mission statement. A mission statement is a formal summary of the aims and values of a company or organization. It’s meant to guide the actions of the organization, spell out its overall goal, provide a path, and guide decision-making.
It provides “the framework or context within which the company’s strategies are formulated.” In comparison, a slogan is typically a short, catchy phrase used in marketing campaigns; a marketing campaign is a series of organized activities to promote a product or service; and a social movement is a collective effort by a large group of people to effect change in society.
Considering the context surrounding our global food challenges, such as the need for sustainable future, food insecurity due to climate change, and the importance of food in our biological and cultural lives, changing the system of food production, processing, and distribution aligns with the key components of a mission statement by outlining the organization's primary objectives and commitment to a particular global cause.
Therefore the correct answer is 1) A mission statement.
