Write an essay of about 100 words on local food and non-local food based on Task 3. Try to use comparative sentences. 例文: Now a lot of people tend to choose local food instead of non-local food. The former is better to human health than the latter. Produced closer to the community, local food needn ’ t travel thousands of miles to consumers. To grow local food, many local farmers use neither chemical fertilizers nor pesticides. As a result, local food is fresher, safer and more nutritious. On the contrary, farmed in places far away mostly with conventional methods, non-local food is less healthy. Furthermore, local food is more environment-friendly. It protects local environment by using organic farming and reducing the trouble of packaging and long-distance transportation. Unlike local food, non-local food needs lots of packaging and must be transported from far away, so it will definitely pollute the environment.
