A.I. Explanation:

Option 1: "Promoting the use of alternative energy sources"

Explanation: This option is incorrect because the text does not mention alternative energy sources at all. The focus of the 'Save Our Seas' campaign is specifically on combating plastic pollution, not energy sources.

Option 2: "Reducing single-use plastic consumption and pollution"

Explanation: This option is correct as the text explicitly states that the campaign aims to reduce single-use plastic consumption and promote recycling. This aligns directly with the main idea of the text, which emphasizes combating plastic pollution in the oceans.

Option 3: "Organizing global conferences on climate change"

Explanation: This option is incorrect because the text does not mention organizing global conferences. The campaign's focus is on community involvement and actions related to plastic pollution, not climate change conferences.

Option 4: "Encouraging the consumption of sustainable seafood"

Explanation: This option is incorrect as the text does not discuss sustainable seafood. The campaign is centered around reducing plastic pollution and promoting recycling, which does not relate to seafood consumption.
