online prescription delivery damages environment?!

I start concering the damages on environment causing by using the online prescription delivery in my profession field.







I have a personal interest for the sustainability issues in my profession field about the prescription delivery system. Because it creates not only lots of garbages from the prescription packages but also dedicates the increase of car gas emission by delivery system.
As many people order the prescription by onlie, it comes to improve the chance of polluting air, too.
Then, what should we do?
Since it's impossible to stop the system which makes people convenient and brings more earnings to business, we have to make other options such as giving discount for direct pick-up or limiting online order per person for one week etc.
