Answer to Question 1

Steel can be made rustproof by applying a coating of metal such as tin or zinc.

Answer to Question 2

The major increase in global production of meat from cattle and milk reflects increases in:

1 . Extensive production systems with range/grass fed cattle and the pastoral systems of developing countries
2 . Intensive systems with cereals being fed and/or supplements
3 . Mixed crop systems, such as cattle eating the residue after the harvesting of cereals
