What actions could you (in theory) undertake that would improve the 'sustainability' of your lifestyle? What might be preventing you from doing these?

Driving a car produces gases that damage our atmosphere i.e. o-zone. Preventing me from making changes would be being unable to travel to destinations as required as public transport isn't effienct enough to rely on but also i could walk or cycle but unfortnately the distance i travel is to far for this to be suitable. As using alot of paper is required for my studys in general without this i would be unable to make notes needed. Unfortunately usage of paper materials is killing trees created by nature, as tree's are natural they have an requirement on earth i.e producing oxygen, therefore recycling is a good sustainable way, i could sustain buy planting trees to replace those used but am unable to do this as my garden isn't bigger enough. To be able to make developments sustainable society is required to work as a whole, without working together this prevents the system from making a valuable difference. The economy create, society consume and the environment suffer. Everything could be sustained if the consumed items are replaced.
