That's why the plastic ones came into existence, to save the number of trees being cut down each year. They said that plastic bags were better for the environment (at one time).
When plastic bags were introduced in stores in the 1970s as a substitute for paper bags, it wasn't for environmental reasons, to save trees. They hit the market and succeeded because they were a lot less expensive to produce and market.
Which is what that 2009 article from the Wall Street Journal says:
"When plastic supermarket bags were introduced in the 1970s, grocers loved them because they cost less than paper bags and didn't take up as much storage space."Market forces, not environmental concerns, drove the success of plastic bags.
Unfortunately, the market didn't account for the negative externalities that plastic bags produce: lengthy decomposition associated with litter and landfill demands, wildlife hazards, and environmental toxicity. To counter the market's failure to incorporate those costs into the price of plastic bags, governments are imposing bans, a step in the right direction. Perhaps a better solution would be to impose a deposit system not unlike the one that applies in many places for cans and bottles, but that seems less practical for bags. Hence the bans.
