Be more green

i do feel bad about what we’re done to the enviornment with our “improvements” in industry, eg coal, gas, cars, etc…and i want to do my bit. im not quite prepared to give up my driving yet as public transport is absolutly terrible here. but i’ve made a start. i work in a cinema and our tills print a receipt for every transaction automatically. if a customer doesnt want their reciept i put them in a bag and recycle them at home. im doing my best to try and save electricity at home but its hard work when i have turtles who have their heat lamp and filter running 24/7. anyone with any tips on how to be greener please let me know
