This is a simple assignment aimed at making sure you get the proper scientific perspective on what makes systems sustainable. i will provide you with the basic first example. it will be up to you to define the two variables (a and b) necessary for sustainability and circle where we are regarding the sustainability. then provide two assessments of that particular example's sustainability (why we are sustainable or not). i realize that we have not covered all of these topics yet. but the idea is to understand the generality of sustainability and then apply it to anything. 1. populations: variable a= birth variable b = death sustainable? : yes (no-variable a higher than b no-variable b higher than a 1. decreasing infant mortality has resulted in more births. this leads away from sustainability. birth 2. increasing lifespan through medicine and nutrition. this leads away from sustainability. 147eaq 2. species diversity: variable a=_ variable b = sustainable? : yes no-variable a higher than b no-variable b higher than a variable a 8a9euen 3. farming: variable a= variable b = sustainable? : yes no-variable a higher than b no-variable b higher than a variable a ਬ =|qe|uew 4. hunger: variable a = variable b = sustainable? : yes no-variable a higher than b no-variable b higher than a variable a gageuen
