What would be a likely environmental impact of a future technological innovation that reduced greenhouse gases and pollution?

i think b. increasing sea levels.

Actually, reducing greenhouse gases and pollution would likely have the opposite effect on sea levels. Greenhouse gas emissions contribute to global warming and the melting of glaciers and ice sheets, which raise sea levels. By reducing these emissions, sea levels would be less likely to rise as quickly.

Instead, a potential positive environmental impact of reducing greenhouse gases and pollution could include improved air quality, reduced harm to ecosystems and wildlife from pollution, and potentially slowing the effects of climate change on the planet.
