စတစ္ေႀကာင္.ၿဖစ္တဲ.ေဘးဒုကၡလဲၿပႆနာအႀကီးစားတစ္ခုၿဖစ္ေနပါတယ္။တစ္ခါကဘုိကေလးဘက္
ကေမြးရပ္ဇာတိရြာကုိသြားၿဖစ္ေတာ.ေခ်င္းေသးေသးေလးထဲမွာဓါတ္ေၿမႀသဇာအိတ္ခြံေတြပစ္ထားလုိ.
ေမာ္ေတာ္ပန္ကာနဲ.ညိွၿပီးခဏခဏဆင္းဖယ္ရတာႀကဳံခဲ.ရဘူးပါတယ္။အဲဒီကတည္းကဒုိ.နုိင္ငံမွာသ

We track its journey that starts with plastic nurdles to a bag that takes nearly forever to completely break down. All plastics are made from petroleum or natural gas. About 3 per cent of all oil ends up as plastic every year. To make shopping bags, first nurdles (plastic pellets) or flakes are melted. The melted plastic is pushed through a ring-shaped hole, which creates a thin, hollow tube of hot plastic. Air is blown into the tube and the film is then cooled and cut.

Retail bags (made of High Density Polyethylene) are easy to spot. They are usually opaque and make a distinct rustling sound. In the UAE, 1 billion bags are handed out every year. Around the world, nearly 1 trillion plastic bags are used every year. No one ever said plastic bags aren't useful. They are light in weight and waterproof. But they have a short, useful life in the hands of the consumer and a long, destructive life after. 
 
Plastic comprises between 60 and 80 per cent of the trash in the oceans. No one is sure how much comes from bags, but the plastic starting materials, nurdles, are commonly found in the marine environment. Once bits of plastic start swimming, they accumulate toxic chemicals on their surfaces. Ocean dwellers scoop them up while feeding. The plastic doesn't break down inside the fish and the toxic-coated material works its way up the food chain.   
 
Plastic bags are one way to carry purchases but other methods are more environmentally friendly. The use of reusable bags is that it saves energy because they don't have to be recycled or recreated for every use. They also save space in the landfill, if one could remember to take them along when shopping.
