If waste decreases due to children's education programme in a wildlife area, this is an example of which conservation method?

Correct answer: Awareness-based conservation

Direct answer: Option A is correct. An education programme is a conservation method when it builds understanding and changes behaviour in a helpful direction. The steps are: children learn why litter harms wildlife; they share or practise the message; less waste enters the area; animals face fewer injuries, choking risks and habitat-pollution problems. Thus the result comes through awareness and responsible action, not through force or exploitation. Option A correctly calls this awareness-based conservation. Option B is wrong because hunting is not the method described and can reduce wildlife. Option C is wrong because habitat destruction means damaging the living place, while the example improves it by reducing waste. Option D is wrong because illegal trade means unlawful buying or selling of wildlife, which is unrelated here. Education is especially useful when local people and children become active protectors. Exam cue: a programme that changes people’s habits for nature is public-awareness conservation.
