Is there a meat conspiracy?

the movie Cowspiracy show how big are the environmental costs of producing animals for food:
- greenhouse gas emissions (more than all transportation),
- habitat destruction (the forest that is being destroyed to provide land to produce soya),
- biodiversity loss (with non-selective fishing gears as for example bottom trawl) and,
- water use (an hamburger requires much more water than all the water used for showering).


if it is that meat production relies in so much resources, why there is not more aware among society about lowering down meat consumption?
most of the people try to turn off lights at home or have a shower instead of a bath, thinking in doing the best for the environment.
but if those things are not the most efficient way to reach a more sustainable way of living, why to keep them?
it is not worth to put all the "eggs in the same basket".
we should have a governmental strategy with policies teaching people how to reduce consumption habits that have higher loads for the environment.
the movie finishes giving the idea that the meat sector has an important economic power that influences political and stakeholders opinions and it is why there is not so much attention to meat consumption.
it can happen in USA but I do not believe there exists such a opinion control since most of people simply prefer to eat meat.
the important thing in my opinion would be that more and more data weighting the costs are available to show in numbers the environmental costs and enabling the comparison of our choices.
