Is it a good idea?

I always take governement and big corporate responsible for the global warming, problem in the world ect... but then i realised that the real problem is people.
They have the power to make things change, but they don't want to change.
They just want to preserve their confort and habits.
So i had an idea.
Let's take Mcdonald and Burger King for exemple.
We know that a lot of people love going to these place, despite the fact that the meat is from mass production , not from good quality, ect.. not really eco friendly.
So what the population have to do is, instead of going to Mcdonald, they all go to Burger King only. Mcdonald will see that they lose a lot of customers so they will try to fit the people need and improve quickly. When all the need of people will be good, then people switch from Burger King to Mcdonald. Burger King then will realise that they are losing clients and will improve and vice versa.
The advantage is that it doesn't require to people to change a lot, just change brand temporary.
And they can do that for all the differents companies, from petrol company to smartphone, ect..

So i don't know if it's stupid or not , you tell me.

I can say this is a pretty good idea. If only more people would care about this.. :/ The world is slowly dying and WE are responsible. Then last minute everyone will want to do something but it will be too late. :(

I'm afraid that there's no way an entire population will get hold of that kind of information without corporate finding out as well.
In fact, they'd probably know the scheme before you did.

This isn't the way to combat global warming.
There isn't an effective way.
