Два аргумента нужно, почему нельзя пользоваться пластиковыми пакетами

We should just improve new technology and change our plastic bottles and packs on paper bags because
1) this technology can save our nature, there will be less litter in our streets and it'll stop pollution.
2) of course, use plastic packs cheaper, but new paper bags can be stronger than plastic. And different shop firms can make different design pattern (дизайнерский рисунок) and it will be great!
