Question

I wonder why I found some pieces of plastic articles and Polythene bags in the soil sample collected from the roadside and the garden

Answer 1

Whether you live in an urban megacity or rural farmland, you surely see plastic bags blowing around anytime you leave the house.

Some blow across roads like post-apocalyptic tumbleweed, while others become snagged in the branches of street trees. Still others end up floating through our creeks and rivers until they find their way to the sea.

But while these plastic bags are certainly not pretty, they actually cause real, tangible harm to the greater environment.

Plastic bags tend to disrupt the environment in a serious way.

They get into soil and slowly release toxic chemicals. They eventually break down into the soil, with the unfortunate result being that animals eat them and often choke and die.
