阅读下面短文，简略回答问题。
As a ninth-grader, Mia noticed that her classmates threw away hundreds of plastic lunch boxes every month, which created a lot of waste and harmed the environment. She felt upset seeing the piles of used plastic boxes in the school trash can every afternoon, so she decided to invent an eco-friendly lunch box to solve this problem.
Mia’s design uses bamboo fiber, a natural and biodegradable（可生物降解的）material. It has a built-in heating pad（垫）that keeps food warm for up to 4 hours, powered by a small rechargeable battery（充电电池）that can be easily charged at home or school. The box also has separate sections for different foods, so they don’t mix.
After testing and improving her design for four months — adjusting the size of sections and making the heating pad more energy-efficient — Mia’s lunch box won the city’s Teen Innovation Contest. A local eco-friendly company now produces and sells it, and many students in her school have started using it. Mia said, “Small creative ideas can make a big difference to the environment. We should all think about how to turn our daily observations into useful inventions, because even a small change can help protect the planet we live on. As long as we have an eye for discovery, everyone can be a little inventor.”
41. What problem did Mia want to solve with her invention?
42. What material did Mia use to make the eco-friendly lunch box?
43. How long can the lunch box keep food warm?
44. What does Mia think about small creative ideas?
45. What small things can you do to protect the environment?
