Either they ask the pupils in the school to pick up every litter they see during recess, and some teachers with a few pupils.
No evidence that schools have been closed due to litter in the UK could be found; however, the UK is taking a firm stand on cleaning up litter. It is possible that schools could be closed if litter is not cleaned up and clean grounds are not maintained.
recyling bins and not LITTER!
It doesn't . It is impossible to get rid of all the litter on earth. Every time you pick a plastic bag up, you can geruntee someone is throwing another one on the ground.
Not enough.
No
Change schools.
If schools get rid of sports, they should honor contracts. What they will do in a particular instance is a different question. Frequently the contracts have clauses that let the schools off the hook.
Get rid of teacher unions
The PH level of used cat litter is so high that it will probably burn the roots of whatever you put it on. Take it to the dump or even better get rid of the cat.
Try putting a not used tea bag or fill your shoes with cat litter not used of course
Put up posters saying slogans like 'don't litter' (if you are looking for basic methods).
Depends on the school. I would imagine in inner ciry schools and colleges, close to 90%.
