Your post really brings attention to a very important issue. You have described people's attitude towards public property and its impact very clearly and concisely. I also believe that the biggest misconception is that people think "it's not my responsibility" when in fact it's everyone's responsibility. Your solutions, such as community awareness, delegation of responsibility, enforcement of laws and setting an example through leadership, are very effective and practical. If the society understands that every public property belongs to everyone and everyone should take care of it, not only will the resources be preserved but also the quality of life for everyone will be improved.
