Reusing and repurposing objects and clothes and countless other things have a large impact. Be it small things like using that tiny scrap of paper you have left from an art project in a journal, or giving up old clothes that don't fit you anymore to friends who can wear them or even bringing them down to a donation thrift store like Goodwill. Any of these small acts can seriously help our environment and help some other people and you, bring their/your carbon footprint/s down.
