If right; all these bottles are of a so called PET kind. Which means it's recyclable. The rest is up to the brainless pigs that have developed the "throw away mentality".
Once they start "throwing" it in garbage cans (if present) things would change for the better. If none available just hold on till you see one.
Conclusion: Cleaning up is not a task for the producers but for the consumers.
If you want to change that habitude, society has to start teaching those elements to be aware of their ignorance. And we are that society, aren't we
I hope that Earth Day will become as significant as Mother Day and Father Day. And as far as Crete concerns maybe like Pascha
True is that adage: "He who yields to rule by wooden heads, becomes himself a fool."
