Я б, во время летнего каникула попытался бы очистить природу!

Собрать людей и начинать убирать мусоры: салофаны, бутулки, баклашки и прочие другие природе! потому что -природа равна жизни сотни тысяч человек, мне бы хотелось хоть немного природе убрать лишный мусор и т.д.

2) я бы ночинал со своего дома и по всей улице,  дальше по району, и я думаю многие желающие присоединились бы и бы с этим делом

3) сперва начинал бы сам, дальше присоединялись бы друзья родственники даже обычные прохожие

4)я бы повесил бы объявление, желающие так же присоединялись бы
