On the first Saturday of April, three clean-up events converge: Keep Houston Beautiful Day, Don't Mess with Texas Trash-Off and the Great American Cleanup.
"Litter and trash seems to be a pervasive problem."
That's Robin Blut, executive director of Keep Houston Beautiful.
She says they perform an annual litter index and Houston falls about in the middle, which means the city does a decent job of clean-up but more public awareness is needed.
"Not only does it spoil the appearance of our landscape, you know it destroys habitat for the wildlife. So I can't stress enough that we all have an important role to play and we can make a difference by doing our part to keep our neighborhoods clean."
Last year 26,000 people cleaned up neighborhoods across the region, removing a million pounds of trash.
