How to write these essays
Essays on the environment follow a simple chain: what the problem is, its causes, its effects, and the solutions. Give the last part the most care. Examiners like practical steps that a student can really take, such as closing a tap or carrying a cloth bag.
For a season or an animal, use your senses: what you see, hear, smell and feel. Avoid numbers that you cannot be sure of. A clear explanation in your own words is worth more than a half-remembered figure.
