Specific Purpose: to inform about the history of plastic bags, its environmental impact and ways to reduce it
You see them everywhere and don't give it a second look. You use them once and then they lose their efficiency and you let the wind decide where they will go. More and more people around the world are becoming aware of the environmental issues surrounding plastic. Today, I’ll talking about its history, the environmental impact if it, and ways to reduce it.

1932, invention of neoprene, polythene in 1933, perspex in 1934, and nylon in 1938 neoprene - found in laptop sleeves or orthopedic braces
polythene - plastic bags and films, and bottles (most common) perspex - safety glass
nylon - bristle on a toothbrush, woman’s stockings

nylon was used for gearing wheels in vehicles and parachute cords. perspex was used for plane cockpits
polythene was used in insulate radars
More modern plastics include
teflon - nonstick pans
lycra - sports wear
decron - material that’s rot resistant used in sailing and in tents Now that I’ve talking about the history, let’s talk about the environmental impact it has today creation of plastic bags allows chemical waste to become mingled with domestic sewage. therefore polluting streams, bays, and oceans when treated sewage is released into local bodies of water roadway litter is not only an eye sore but weather, traffic, and animals move litter into gutters, lawns and landscaped areas, alleyways, and parking structures.
