Many people say they need to have something in order for them to be happy, but need is something we need in order to survive like food, water, air, shelter, and warmth. Buying a car or phone isn't a need, we won't die even if we don't have them. Want is extra things to keep us happy and comfortable like a transportation to go. If we can sort out what we actually need and what we just want, we can save many resources not buying unnecessary products like plastic toys, models, etc. We don't need a Lego set in order to live. For example, if we can save our money buying Lego the plastic pieces might become trash and end up floating in the ocean or laying there in a garbage dump. If we think buying little things won't hurt the planet, each small purchase adds up until we kill many habitats and ecosystems. We have to start thinking to do the right thing and buy important things that can really help you when you buy it.

I agree, sometimes we feel like we are just buying something little, but if everybody thinks this way and we keep buying them, it is going to create a lot of pollution. We should really think about whether what we are buying is really necessary. We don't need thirty pairs of basketball shoes.
