This is right. we must clean our surroundings and keep it clean.if not,the mosquitoes,house flies gather on waste areas in our surroundings and may trouble us and cause many diseases and epidemics such as malaria,dysentry,typhoid etc.,
if we keep our surroundings neat and clean,our neighbours may follow the same too. 
so,keep our surroundings clean and green and motivate others to do the same.
