Plastic Bags
Environment
Since plastic bags are not biodegradable, they pollute oceans, farms, cities, rivers
Marine life impacted by this pollution may fall ill if it consumes the plastic (plastic bags are often mistaken for jellyfish and plankton)
Plastic bags increase the mosquito population by collecting rainwater and providing them a breeding-ground
Plastic litter often blocks drainage systems which can cause unnecessary flooding
Flooding can kill wildlife, damage ecosystems
Businesses
Contributes to higher prices in stores, as price for plastic bags must be accounted for (unless consumers pay for them separately)
Plastic bag manufacturing provides thousands of jobs in Canada
90% of plastic bags used by Canadians are manufactured by Canadians; this industry provides a lot of people their livelihoods
Main topic
Consumers
Plastic bags are significantly cheaper than reusable bags; cheap, efficient vessel to transport things
Feeds into consumer culture - easy to use and dispose of, no need to maintain/keep lying around like a reusable bag
The large scale detrimental effects may indirectly have a negative effect on consumers (i.e. food, atmosphere contaminated as a result of pollution, increase of mosquito population causing a rise in West Nile and Triple E Viruses, etc.)
Government
Plastic bags are often littered. Litter costs tax money
Have the power to either ban or allow the use of plastic bags; ongoing debate
Agriculture
Plastic bag water pollution can have a negative impact
on aquatic livestock
Flooding as a result of plastic bag drainage blocking can be damaging to crops
