Show transcript
Farmers use chemicals called fertilisers to produce more crops.
Farmers use chemicals called pesticides to produce more crops.
Some pesticides kill insects and this helps crops to grow because they are not being eaten.
Some pesticides kill other plants (weeds) that compete with the crops to grow.
Fertilisers and pesticides can be harmful to the environment and wildlife.
