Thousands of volunteers in red shirts worked to clean up trash from city streets and waterways Thursday, as part of the Lilly Global Day of Service.
Along with those efforts, Metro police have promised to step up enforcement for those who violate littering laws, focusing specifically on those who flick away their cigarette leftovers.
"They should put the trash in the containers. That's why the containers are down here," said Indy resident Mack Davis.
It's a basic rule of courtesy and conscience for Davis, but area conservation groups said the litter bug is far too often biting Indianapolis streets, parks and waterways.
"What we're doing is, we're just bringing awareness to it for the officers," said Metro police spokesman Michael Hewitt. "We've sent out a couple of emails just reminding officers to be aware, more cautious of it."
Workers for Keep Indianapolis Beautiful say discarded trash can clog storm drains and damage the natural habitat for fish and other wildlife.
"Once they throw it out their car window, that will probably eventually end up in our water system," said Ashlee Fujawa with Keep Indianapolis Beautiful.
While they work to get things clean, people like Davis are asking Hoosiers to help keep it that way.
"Help keep our city clean," he said. "Nobody wants to live in a dirty place, a dirty city, a dirty street."
People who are caught littering could face fines ranging from $75 to $150.
