Nowadays, plastic is considered a great environmental and health hazard. Plastic bags and food wrappers are consumed by animals leading to digestive problems that can cause their death. Animals can get trapped with bags around their heads causing them to suffocate. Plastic bags tend to disrupt the environment in a serious way. They get into soil and slowly release toxic chemicals. They eventually break down into the soil, with the unfortunate result being that animals eat them and often choke and die. The plastic pieces are polluting even our oceans causing negative impact on hundreds of different species of marine plants and animals.
On the other hand, there are positive points, as well. Plastic bags are durable and weatherproof, stronger than paper and resistant to many chemicals. They are the most convenient packaging option, good for branding and cheaper than paper or cloth packaging. Most of the plastic bags are biodegradable, i.e. they can be broken down in a reasonable amount of time when thrown in the waste. Biodegradable plastic bags leave no trace behind and are safe for the environment.

All plastic is not bad; it is important to prevent misuse and disuse of plastic which harms the flora and fauna. For branding jute is a better alternative as it can be reused and recycled. Achieving a balance for planet earth for prosperity is the underlying motto. The ban , if any , is imposed to make us (corporations and consumers) realise that we belong to EARTH. "The world has enough for everyone's needs, but not everyone's greed," Mahatma Gandhi said in what is now one of his best-known quotes. Its ubiquity is for good reason. Innovation for viable alternatives as enshrined in holistic marketing is the new opportunity!

I was speaking with our University's vet and she mentioned that live decap is the better route to take if you're planning on doing any histology after death. Does anyone have any further information on this/any sources that show this? 
Relevant answer
Answer
Most ethical requirements (from government or institutions) require justification for live decapitation. It depends on what you are measuring- you should look to see if a particular anesthesia is known to have an effect on your measurement, and if that exists it might be worth asking for permission to do live decapitation. But in all likelihood, you won't have permission to do so within your lab's existing ethical permissions (unless someone has asked for it already).
Another point to think about is this- will the stress of the live decapitation affect your measured target more than anesthesia? Acute stress is often a purposeful manipulation and is known to affect many brain parameters, so depending on what you're measuring you might be affecting things more by NOT using anesthesia. Really depends on what you're measuring.
