1. One of the solutions to littering is propaganda. People will walk or ride or bike with slogans about stop littering. In addition, local authorities will tell the civilians about the serious consequences of littering to the environment and our surroundings. This measurement will raise people's awareness about protecting nature.

2. This measurement will have a big impact on the conservation of plants and animals because plants and animals are not killed by themselves, most of them are killed by humans so this solution will directly affect the humans' mind and awareness of the importance of the environment.

3. As a student, I can take part in the propaganda progress by telling my parents and relatives of the results of destroying the environment so that they will protect it.
