Environmental cases involving toxic substances often face challenges such as proving causation, dealing with complex scientific data, and overcoming political and economic pressures. Establishing a direct link between exposure and health outcomes requires extensive research and expert testimony. Furthermore, these cases can be prolonged, costly, and require collaboration between various stakeholders, including scientists, lawyers, and affected communities. Despite these challenges, cases like the one led by Erin Brockovich highlight the importance of perseverance and scientific integrity in addressing toxicological issues.
