Create a short talk (like the space expo talks) in which you describe the current situation and then describe the technology and/or policies that could mitigate this problem.
You could look at electricity generation, lung cancer, homelessness, education, employment, shopping, farming, household pets, batteries, death... whatever you feel passionate about. If you need inspiration, look at the 17 sustainable development goals of Agenda 2030.
This should be a "Yellow and Green hat" talk: optimistic and creative in solving problems. But don't neglect the other "thinking hats" - include statistics, hard facts, emotions and risk awareness.
Share your presentation/manuscript from the outset so your teacher can see your progress. If doing group work, take extra care to work in one (1) Google document and share all that you do. Good communication with your classmates and teachers is essential for this to work.
