The explanations is true based upon the graph B.) II only . Therefore , B.) II only is correct .
The assertion that more land is needed for plants than combined beef to produce 100 grams of protein is not accurate when considering the overall efficiency of protein production.
While it's true that beef is a concentrated source of protein, the argument oversimplifies the complexities of resource use in agriculture.
Beef production involves significant resource input, including large areas of land for grazing or growing feed crops.
Additionally, the environmental impact of livestock farming, such as methane emissions and water consumption, raises concerns about sustainability.
On the other hand, plant-based protein sources, such as legumes, grains, and vegetables, can be more resource-efficient.
Plants may have lower protein content per unit of weight, but they are not solely composed of protein.
They provide a diverse array of essential nutrients, fibers, and antioxidants.
Furthermore, modern agricultural practices, including crop rotation and precision farming, contribute to optimizing land use and minimizing environmental impact.
The comparison between plant and beef protein production requires a holistic view that considers not only protein content but also the overall efficiency, environmental impact, and nutritional value of each food source.
Sustainable and balanced diets often include a mix of plant and animal-based proteins, emphasizing the importance of responsible agricultural practices.
