The actions of purchasing a disposable water bottle, using it several times, and then throwing it in the garbage can be evaluated in terms of conservation as follows:
While reusing the bottle several times is a better option than using it only once or opting for a new single-use bottle each time, ultimately disposing of it in the garbage is not a sustainable practice. Ideally, the individual should either recycle the bottle or use a more environmentally friendly option, such as a reusable water bottle made of materials like stainless steel or glass.
Therefore, the best evaluation of these actions in terms of conservation would align with this thought process: "It is better than using the bottle only once, but they should recycle the bottle."
