well for a human that would be gross because you might get a bug or any other kind of bacteria in your mouth and might make you sick but for animals i would say its okay cause it helps their upse stomach and sometimes the vomit it back up but i used to eat grass when i was little and i wasn't suppose to....but that is a good question though
Grass poking through a crack in a sidewalk is an example of secondary succession. This is because the sidewalk already existed, and the grass is growing after a disturbance (such as the cracking of the sidewalk) has occurred, allowing for new plant growth in the area.
The roots of the grass may further widen the crack in the sidewalk as it grows, causing potential trip hazards. Additionally, as the grass grows, it can retain moisture which may lead to further deterioration of the sidewalk over time. If left unchecked, the grass can also make the sidewalk more slippery when wet.

The grass growing through a crack in a sidewalk can contribute to physical weathering by exerting pressure on the concrete as the roots expand, potentially widening the crack. Additionally, the roots can facilitate chemical weathering as they release organic acids that can weaken the sidewalk's structure over time. Ultimately, this combination of physical and chemical weathering can lead to further deterioration of the sidewalk.
To effectively remove grass from sidewalk cracks, you can use a sturdy tool like a screwdriver or a weeding tool to dig out the grass roots. You can also pour boiling water or vinegar into the cracks to kill the grass. Regularly maintaining the cracks by pulling out any new growth can help prevent grass from growing back.
One of the most common ways to level grass is by using sod. If sod is laid on grass, it can level it with the sidewalk.
Sidewalk, smoother surface.
A ball moves faster on a sidewalk than on grass because the surface of the sidewalk is smoother and provides less resistance. The grass surface is uneven and offers more friction, which slows down the ball's movement.
It is easier to pull a wagon on the sidewalk than on grass because the wheels of the wagon roll more smoothly on a hard, flat surface like the sidewalk, compared to the uneven and soft surface of the grass which creates more resistance. The sidewalk provides a stable and firm base for the wheels to move efficiently.
A ball would generally roll faster on a sidewalk than on carpet grass due to the smoother and harder surface of the sidewalk providing less friction and resistance. Carpet grass has a rougher texture that can slow down the ball's movement.
To effectively remove grass from your sidewalk, you can use a combination of tools such as a sturdy garden trowel or knife to dig out the grass roots, a weed killer spray to prevent regrowth, and a stiff brush to sweep away any remaining debris. Regular maintenance and vigilance can help keep the sidewalk clear of grass.
If you want you lawn to stop growing grass no but, if you don't... yes
