Refuse, Reduce, Reuse & Recycle.
When friends are out shopping, I can refrain from purchasing items that aren't necessary, I can refuse.
I can definitely donate some clothes that are not of use anymore, and I can reduce.
Instead of using plastic forks and spoons, I invested in silverware and can wash it instead of going through plastic forks and spoons every day.
And always recycle, we have recycling bins in our dorms, so it would be weird not to.

After calculating my carbon footprint, I was made aware that I haven't been making the smartest choices for the environment and that I need to be more conscious of my everyday choices.

well I did not find seaweed to eat but I had sushi the other day and I was dried seaweed.
