Question

one way to reduce your ecological footprint (and improve your health) is to change your diet and eat lower on the food chain. consider the table below.
if you did not want to completely eliminate meat from your diet, eating as your protein would be the best choice while eating would be the worst choice.

Explanation:

Step1: Analyze the protein per acre

We need to compare the grams of protein per acre for different food sources. The higher the grams of protein per acre, the more efficient (in terms of protein production per unit land) the food source is.
For meat - based sources (cattle (beef), pigs, chickens) and plant - based sources (soybeans, wheat, sunflower seeds, black beans).
Looking at the "Grams of protein/acre" column:

• Cattle (beef): \(8330\) grams of protein/acre
• Pigs: \(76720\) grams of protein/acre
• Chickens: \(163212\) grams of protein/acre
• Soybeans: \(513066\) grams of protein/acre

Among the meat - based sources (chickens, pigs, beef), chickens have the highest grams of protein per acre (\(163212\) grams of protein/acre). Among all the sources (including plants and animals), beef has the lowest grams of protein per acre (\(8330\) grams of protein/acre) among the given options. Since the question is about meat sources (as we are not completely eliminating meat), we compare only the meat - related rows (cattle (beef), pigs, chickens) for the best meat - based choice and all rows (but focusing on the meat - related ones for the worst in the context of the question's "if not completely eliminate meat" part)

Answer:

Eating chickens as your protein would be the best choice while eating beef would be the worst choice.
