What is kaitiakitanga in the context of chemical use?

• A. The responsibility to protect waterways and environments through careful chemical use and disposal.
• B. The law requiring recycling.
• C. The design of chemical labs.
• D. A method for balancing equations.

Answer: (A)

Main idea: environmental responsibility in chemical use, focusing on protecting waterways and ecosystems through careful handling, storage, and disposal. Kaitiakitanga is a Māori concept of guardianship or stewardship of the land and environment. In chemistry, it means acting in ways that safeguard the environment: preventing spills, using proper containment, disposing of chemical waste correctly, recycling where appropriate, and avoiding releases into drains or waterways. This mindset aims to minimize harm to ecosystems now and for future generations.

So, the statement that best fits is the one about protecting waterways and environments through careful chemical use and disposal. The other options describe laws, lab design, or mathematical methods, which don’t capture this environmental guardianship idea.
