#2. If you have a choice, which part of the motto ‘reduce, reuse, recycle’ is the best option for the environment?
Reducing the amount of waste you use is the best choice for the environment. If you can’t avoid it, you should try to reuse your waste. If that’s not an option, you should recycle what’s left.
