Afforestation, the planting of trees in barren areas, increases biomass and helps mitigate global warming by sequestering atmospheric carbon dioxide through photosynthesis. Most plastics are synthetic polymers that are non-biodegradable, meaning they cannot be broken down by natural biological processes and persist in the environment for centuries, causing pollution. All statements are correct.
