In my opinion, everyone can reduce his footprint if they be aware about what they need and what they want. Many objects seem necessary but it is not true.

I agree with you, only we only pay attention when we have an idea of what we are doing. As a student I don't pay attention to what I consume.

i am agree

I agree. In the modern era, it's very common for people to buy things not because they need them for survival or convenience, but rather because they "look nice" or are attractive to them in some other way. We must realize when this is happening, and try to cut back on purchases like these. That way the materials otherwise used to make these products can be diverted for more environmental purposes, and your money can be spent on something more essential to your everyday life.
