Answer:
Question 1 can be answered by science. Scientists have conducted studies and research on the effects of heavy metals like lead and arsenic on human DNA. They have found that exposure to these metals can cause damage to DNA, leading to health problems and diseases.
Question 2 is a more complex question that cannot be answered solely by science. While science can provide information on the effects of heavy metals on ecosystems and human health, the decision of whether industries should be penalized for releasing heavy metals into the environment is a matter of policy and ethics. It involves weighing the economic benefits of the industry against the potential harm to the environment and human health. This decision requires input from multiple stakeholders, including scientists, policymakers, and members of the affected communities, and involves considerations beyond just scientific evidence.
