I will use cloth bag instead of plastic bag when I go for shopping.

Plastics can take anywhere from 20 to 500 years to decompose, depending on the material and structure. Additionally, how fast a plastic breaks down depends on sunlight exposure. Like our skin, plastics absorb ultraviolet (UV) radiation from the sun, which breaks down the molecules.

In 2019, the CIEL estimated that production and incineration of plastic would add 850 million metric tons of greenhouse gasses to the atmosphere – equivalent to 189 coal-fired power plants. By 2050 this could rise to 2.8 gigatons of carbon dioxide per year – or 615 coal plants’ worth.
