Чи чисте твоє довкілля?

Monitor and test your environment to decide is it clean or dirty?

Our streets, parks, rivers and lakes are dirty with sweets' wrappers, chips bags, plastic boxes and bottles. People don't worry about nature and leave rubbish and litter after being on picnics on nature.
We dump litter into the water. 
All year round we burn rubbish, plastic, leaves contaminating the environment.
We have not any fresh air to breathe and destroy the ozone layer.
We do everything to change the environment for worse.
