The quest for cheap and plentiful meat has resulted in factory farms where more and more animals are squeezed into smaller lots in cruel and shocking conditions. Such practices have resulted in many of the world’s health pandemics such as the avian flu. Worldwide, livestock are increasingly raised in cruel, cramped conditions, where animals spend their short lives under artificial light, pumped full of antibiotics and growth hormones, until the day they are slaughtered. Meat production is water-intensive. 15000 litres of water is needed for every kilogram of meat compared with 3400 litres for rice, 3300 litres for eggs and 255 litres for a kilogram of potatoes.

What is the most rational and crucial message given by the passage?

Correct Answer: Environmental cost of meat production is unsustainable when it is produced through industrial farming.

Step-by-step Explanation:

1. Analyze the Passage Details:
The passage points out the severe drawbacks of raising livestock in industrial factory farms, highlighting two main dimensions of concern:
- Health and Welfare: Animals are crowded in cramped, cruel conditions and pumped with growth hormones and antibiotics, creating breeding grounds for global health pandemics like the avian flu.
- Resource Intensity: Meat production requires an immense volume of resources. Specifically, it demands 15,000 litres of water to produce just one kilogram of meat. In contrast, producing a kilogram of rice takes 3,400 litres, eggs take 3,300 litres, and potatoes require only 255 litres.

2. Identify the Core Message:
By comparing the astronomical water footprint of meat (15,000 litres) with that of crop-based alternatives, the passage underscores that industrial meat production places a heavy and disproportionate demand on crucial natural resources like fresh water. This excessive consumption of resources, combined with the ecological risks of disease, demonstrates that the environmental footprint of industrial farming is not viable in the long term.

3. Conclusion:
Therefore, the most rational and crucial takeaway is that the environmental cost of meat production is unsustainable when it is carried out through mass industrial farming practices.
