Essential for fertiliser, phosphate rock is only found in a handful of countries, including the US, China and Morocco. For example, farming a single crop (monoculture farming) on a piece of land with the help of pesticides — the primary mode of farming in the world — has caused widespread soil degradation throughout the world. Traditional agricultural breeding approaches for biofortification are time consuming but can enhance the nutritional value of some foods; however, advances in molecular biology are rapidly being exploited to biofortify various crops. Because it’s so cheap and versatile, palm oil is the most common vegetable oil in the world, used in everyday products like bread, chocolate, soap, lipstick, and margarine.
