Industrial exhaust emissions are an important reason for the increase in greenhouse gases, but there are still a large number of greenhouse gases coming from the bottom. Methane is produced in the bottom sediments of water bodies such as lakes, ponds, and rivers, and the methane mainly comes out of the water in the form of bubbles and enters the atmosphere. Found that nutrient-rich water bodies release more methane, so experts have suggested that in order to reduce greenhouse gas emissions in water bodies, the abuse of fertilizers should be limited. For the above argument to be true, which of the following premises must be added? ['Methane emissions from water sediments are greater than industrial exhaust.', 'Methane is the main component of greenhouse gases.', 'Chemical fertilizers easily cause pollution to the environment through water bodies.', 'Abuse of fertilizers can easily bring too much nutrition to water sediments.']
