Give examples of how humans have increased their food supply and what effects these methods have on the environment overall.
This is really one where you need to give ideas and we will comment if you like. I am sure this question has been answered before on here. Anyway you already have two examples in the question. Some others might be
Cross breeding of plants.
Selective breeding of single strains of plants or varieties of animals with particular characteristics (e.g high milk yield)
Huge fields of monocultures which have needed hedge rows to be grubbed out (in the UK) and forests to be cut down (South America).
Discuss concerns you have about the overall safety of the food you eat?
These are YOUR concerns. However, you might want to read up on what is meant by the terms 'risk' and 'hazard' so that you use them correctly. Explaining what you understand by these terms can make a good opening to an account on this subject.
