Plastic is harmful for nature.When plastics are burned,they produce toxic gases and smoke.Most plastic wastes littering the road sides cause disease causing microorganisms. To avoid plastic we can use steel,clay,aluminum,etc. I prepared clay pot at home. Foremost health benefits of clay pot cooking came from its ability to circulate steam throughout cooking. This provides plenty of moisture and means that you can cook with less oil and fat. If you season your pot properly, it will become durable and likely last for a long time.
