Wants and needs are very relative to the experiences and desires of each individual. Strictly speaking the only things anyone NEEDS are shelter, food, and water. But others would argue that in the world we live in, we need to be productive members of society, that we need to be educated and in order to do both we need technology. But it is important to strike a balance between wants and needs that also retains a healthy balance for our surroundings - especially the environment. I would argue that there are many things we all need beyond the basics, but what we decide that we need should be directly benefiting us and shouldn’t be harming the environment when used/dealt with in duration.
