Final answer:
The career that could help with the concern about the impact of a new factory on the environment is environmental engineering.
Step-by-step explanation:
The environmental science career that could help with the concern about the impact of a new factory on the environment is b) Environmental engineer.
Environmental engineers specialize in finding solutions to environmental problems, including assessing the impact of industrial activities on the environment. They design and implement strategies to minimize environmental damage caused by factories, such as developing pollution control systems and designing systems for waste management and treatment.
For example, an environmental engineer could analyze the emissions produced by the new factory, evaluate its potential impact on air and water quality, and propose measures to reduce pollution and minimize harm to the environment.
