Environmental Science Contributions and Policies

The video discusses Crawford Greenewalt, a DuPont engineer, and his collaboration with biologist Ruth Patrick during the Manhattan Project. Patrick introduced an ecosystem approach to assess the environmental impact of DuPont's activities on the Columbia River. Greenewalt supported thorough research to ensure no harm to natural life, emphasizing DuPont's commitment to environmental responsibility.

Who was Crawford Greenewalt and what was his role at DuPont?

• A historian documenting environmental changes

• A chemist involved in the Manhattan Project

• An engineer with oversight responsibilities at DuPont

• A biologist who worked for the Academy of Natural Sciences

What was Ruth Patrick's contribution to environmental science?

• She pioneered the ecosystem approach in ecology

• She wrote a book on environmental policies

• She developed a new chemical for pollution control

• She invented a device to clean rivers

What was the main focus of the ecosystem approach advocated by Ruth Patrick?

• Focusing solely on fish populations

• Measuring air pollution levels

• Studying the entire ecosystem and its interactions

• Analyzing the chemical composition of water

What was the revolutionary policy implemented by DuPont regarding plant operations?

• Assessing river conditions before starting operations

• Building plants without environmental assessments

• Ignoring environmental impacts for cost savings

• Focusing only on air pollution control

How did Crawford Greenewalt ensure DuPont's environmental responsibility?

• By supporting thorough environmental assessments

• By cutting costs on environmental assessments

• By prioritizing profit over environmental concerns

• By ignoring upstream river conditions

What was Crawford Greenewalt's response to the cost of environmental assessments?

• He often refused them due to high costs

• He always supported them despite the costs

• He only approved them if they were cheap

• He ignored the need for assessments

Why was it important to assess different parts of the stream according to Ruth Patrick?

• To find the best fishing spots

• To compare upstream and downstream conditions

• To measure air quality

• To locate new plant sites

What was the impact of Greenewalt's policies on DuPont's operations?

• Decreased production efficiency

• Enhanced environmental responsibility

• Increased pollution in rivers

• Reduced focus on environmental issues
