People (I mean masses) will never stop doing pleasant but dangerous things except...

... if it's too expensive or forbidden.

People continue to drink alcohol, eat sugar, smoke tobacco even if they know it's terrible for their health. 
Yes, some people change their behavior. But it's not a lot of people and it will lever be.

The only way to make people change habits and consume less bad things is to make these things more expensive and tax them.
Lobbies against sugar damages got this. Just google "sugar tax".

And it works. See this graph of tobacco consumption in Australia:




Producing a ton of beef requires so much water, consume so much resources, pollute so much, create so much diseases that the real cost of a piece of meat is far bigger than its price tag.

This price of these collateral damages of beef meat should be added to their selling price too. Same for oil.
