Final answer:
Source 5 provides information about the resource requirements of cow's milk production and how it affects food security. It also supports the claims in Source 4 about the use of edible crops for animal feed and the need for sustainable food systems.
Step-by-step explanation:
Source 5 provides new information about the opportunities and obstacles related to humans consuming cow's milk. It states that currently, 34 percent of human-edible crops are fed to animals, which reduces calorie and protein supplies. If society continues on its current dietary trajectory, there will be a 119% increase in edible crops grown by 2050. This suggests that the production of cow's milk requires a significant amount of resources and has implications for food security.
Source 5 corroborates the claims made in Source 4 about the practice of using human-edible crops to produce meat, dairy, and fish for human consumption. Both sources highlight the fact that a large portion of edible crops is dedicated to animal feed, which can impact the availability of food for human consumption. They both emphasize the need for transforming food production and distribution systems to be more sustainable and nutritionally adequate.
