1. As a group, write down two challenges in terms of sustainability you would face when developing a sustainable food supply for a Martian colony (or any area that is severely lacking in agricultural resources). Keep in mind the space and time limitations you have (1000 acres of growing space and several months’ worth of food). 2. A sustainable food supply requires more than just resource management. It also needs to provide people with suffi cient calories, macronutrients, and micronutrients for health, productivity, and well-being. Write down at least two challenges of producing such a diet sustainably in an area severely lacking in agricultural resources.
