1 and 3

The correct answer is option 2:  1 and 3

Conventional agriculture relies heavily on chemical fertilisers and toxic pesticides etc., which enter the food supply, penetrate the water sources, harm the livestock, deplete the soil and devastate natural eco-systems.

Explanation:

• It enters the food supply and penetrates the water sources: Chemical fertilizers can leach into water sources and affect the food supply through contamination.

• Although, expensive, but beneficial for the fertility of the soil: While chemical fertilizers can improve soil fertility in the short term, they can also deplete soil organic matter and reduce its long-term health.

  It devastates the natural eco-system: Chemical fertilizers can cause significant environmental damage, including soil degradation, water pollution, and harm to beneficial microorganisms and wildlife.
