Question

we cannot say that plastic is an eg of natural resources why

Answer 1

Plastics are manufactured materials that come from natural resources such as oil, gas and coal (fossil fuels). ... Because the resources used to make plastic take so long to form and are so valuable, it's important to think of plastic itself as a valuable resource and recycle it wherever possible.
Plastics are man-made products that come from valuable non-renewable resources like oil, gas and coal. Plastic has been the most common item collected on Clean Up Australia day for 20 years.

Hard plastics can generally recycled through kerbside recycling programs, where they are then melted, stretched, cut and moulded into a recycled product.

Some supermarkets now offer a drop-off point for recycling soft plastics including shopping bags, cling and bubble wrap, pasta and rice bags, and biscuit packets.

Answer 2

Answer:

plastic is formed by chemical processes and can't be destroyed so it's not a natural resource
