Going green 6 Exercise 3A, page 117 why organic farming?0:01
Modern farming methods allow farmers to produce large amounts of cheap food.0:21
There is a cost to the environment, though, because intensive farming uses a lot of chemicals such as pesticides and fertilizers that damage ecosystems and destroy wildlife.0:27
It also uses a lot of energy because of the amount of machinery used.0:40
Not only does the soil suffer from these methods, but the quality of the food is reduced too.0:45
Organic farming, on the other hand, aims to protect the environment while producing high quality food.0:52
Natural fertilizers such as manure and compost are added to the soil instead of man made or chemical fertilisers.0:58
Organic farmers also choose natural methods of pest control.1:06
They use ladybirds to combat green fly and burn weeds or pull them out by hand instead of spraying them with chemicals.1:12
They also use traditional farming methods such as rotating crops to different fields each year to maintain the nutrients in the soil.1:21
Organic food may be a bit expensive, however, it is healthy, tasty, and better for the environment.1:30
