Task 6: Writing
In my opinion, organic farming is preferable to chemical farming because of the benefits to the environment and people. (Topic sentence) To begin with, organic farming keeps the soil rich. For instance, natural waste from animals are used as fertilisers, making the soil richer in minerals. (Points and details) And then chemicals harm the land and health of people. As we all know, chemicals can stay in soil and underground water, which in turn will affect humans. (Points and details) Finally, organic food is generally more nutritious. There was a case of watermelons exploding because chemicals had been used in them. So they contained too much water and tasteless.
