Same with frozen food that has condensed water around the packaging, I imagine. What if you put some frozen peas at the bottom or even the sides of the bag, and then you walk home for 15 minutes or so? Isn't the bag going to get brittle from the water, and break?
I grew up using paper bags. They can tear, but plastic bags probably tear just as much; they are so thin. I think the main reasons we use plastic now is because the handles make it easier to carry, and they are cheaper for the stores to buy. The paper ones did have an advantage though. Paper is a much better insulator than thin plastic. So cold items stayed cold longer on hot days. Which ironically means cold stuff wouldn't get as much condensed water around the packaging. I don't really remember that ever being a major problem.
As for saving the environment, that depends on how you look at it. Both types of bags can be recycled, but most people just don't do that. I keep them and use them as trash bags, but at the end of the day they do end up in the trash. But that's another difference. A lot of people argue that paper will biodegrade and is therefore better for the environment. But I remember reading an article where an environmental engineer drilled down into a landfill. He got down far enough to pull up a newspaper dated from the time J.F. Kennedy was assassinated. It was still in pristine condition, not even yellowed yet.
Once stuff is packed into a landfill and it's all encased in lime/clay/whatever, it's properly sealed and protected in there. It lasts a lot longer than people think. So, with that in mind, plastic bags actually have an advantage in that they take up less space in the landfill and it won't get full as fast. Depends on your perspectinve on the issue.
