Some substitutes for plastic are starch from corn or wheat, corn syrup, ad even potatos.
1)We can use cloth bags ,or paper bags instead of plastic bags while going for shopping.
2)Plastics take several years to decompose,
we can use paper bags in place of polythene bags.
Paper bags are better than plastic bags, because they will biodegrade in the ground in a few weeks.
bags, bottles, cups etc, most things made of plastic have replaced a material, appart from tech which has been designed to be plastic
fabric bags
paper bags
It keeps the cuttings from being dehydrated, as it prevents loss of moisture, and so the cuttings will not wilt and dry out.
ADVANTAGES1. Polythene film is one of the most lightweight and durable packaging mediums available.2. Plastic packaging makes an important contribution to reducing food spoilage rates.3. Polythene ducting is compatible with most fans, heaters, air conditioners, air handling units, etc4. Polythene Bags use less energy and resources to create than glass or paper.5. Clear polythene allows recipients to view the contents (such as a magazine cover) prompting them to open immediately if the item is of interest or expectedDISADVANTAGES1. Polythene is not biodegradable, and if dumped in the soil causes harm to the plant life, as the toxic substances of polythene get blocked among the soil particles.2. Polythene threatens the life in the water bodies. The chemicals in polythene affects the survival of flora and fauna of the aquatic and marine Eco-systems.3. Polythene is also likely to clog the drains causing problems in the water flow of the pipes. The pipe blockages would cause flooding and the free flow of water is disturbed.4. Polythene is harmful for animals if swallowed. It solidifies inside the abdominal cavity which ultimately becomes lethal to the animal.5. In most households poly bags are used to preserve food items. It has been found out, the colourful poly bags contains lead and cadmium which are toxic and cause adverse effects to human health.6. If polythene is burnt in open air Hydrogen cyanide which is carcinogenic (cancer causing) is released.7.Hydrogen cyanide causes environmental pollution and health hazards
Polythene is not biodegradable * Polyeethene threatens the life in the water bodies. The polyethene articles (e.g. six pack rings) affects the survival of animals the aquatic and marine eco systems. * Polyethene is also likele to clog the drains causing problems in the water flow of the pipes. The pipe blockages would cause flooding and the free flow of water is disturbed. * Polyethene is harmful for animals if swallowed. It can accumulate in the bowels which ultimately becomes lethal to the animal. * In most households poly bags are used to preserve food items. Reused bag may be contaminated by materials harmful to human health.
Polymers as the name suggests are used in making polythene, polythene materials like hand bags have become integral part of our lives, though plastic is non biodegradable in nature and hence its excessive use can cause environmental problems. Polymers have a molecular structure that us linked together strongly hence can be used for holding up heavy pressure and carry heavy loads, a relatively thin layer is plastic is more strong then any other material.

hazards of polythene bags
we should discourage the use of polythene bags as they are not biodegradable and thus cause pollution..
