This is a really good question. The short answer is if you reduce your dairy consumption, less new dairy cows will be bred going forward.
It will begin to ease the burden on the environment from dairy.
It will slow down the amount of new calves and dairy cows having to suffer.
It won't be an overnight change.
But by spending your hard earned dollars on dairy alternative product, you can help to start reducing the impacts.
You can start doing your bit for the environment and animal welfare.
The less money large dairy farming corporations make, the more they will invest in alternatives.
And this is how i came to believe that...
