Research-based paper… Sources I listed are tentative and more can be used/thos

Research-based paper… Sources I listed are tentative and more can be used/those listed can be not used if necessary.
Professor instructed me to use 2/3 of the paper to describe the problem (corporations harming the environment, lobbying against solutions, etc. The remaining 1/3 of the paper should be a solution or possible suggestion that could potentially fix the problem. I have uploaded my one-page description of the assignment that includes the problems listed and my tentative thesis.
