1. We can accommodate both those who want free entrance and who offered to pay... u make Saturday and Sunday pay entrance the other day free
1A. since the entrance is free we can create many way to make money .. T shirt, hat , many other tradition product for sale the income from those sale can be used to finance for maintenance and plant more trees
2. About where u live people are conscious about the consequences of throwing waste disposables.... i don't know where u live but even in West have hard time making people to respect run, the most popular run to break is traffic rule , speed, drink and drive, to buckle up seat belt was the hardest .. so the police use enforcement to correct the people mistake then after many years and tries it become next to nature to buckle up seat belt otherwise every where u go people are the same they don't follow rule so u put enforcer even where u live ask someone how was it in the beginning people might have resistance the bad habit die hard
3. the beauty of enforcing the rule .... u give fine for those who break the rule and by itself it finance the cost of policing ... in Ethiopia if u pay one police officer i being generous and let say we pay salary for one officer 10,000 birr per month so if the fine is 1000 birr then the officer should pull over ten driver to break even trust me he will write ten ticket a day if not one ticket a day that is pure profit for the city to hire more officer and pay them and still make money
4. look this guy picking up trash with gripper.... we can locally made the gripper so that we don;t touch the trash.
5. we always see obstetrical as opportunity , and opportunity as gift to improve
