Because EVs are quite expensive and need lots of infrastructure. We basically have to double our electricity production when we are still struggling to just get the current load without EVs on renewables. We need to upgrade our power grid with more carrying capacity and more storage, which is neither cheap nor easy. And even then, that just solves cars, not transport of goods. There is a whole load of additional problems to solve there, like hydrogen production and distribution or synfuels. This "just use EVs" alone is not viable for anything but the industrialised countries, and even there most are struggling with the cost and public support. Here in Germany, nobody wants any more windmills or power lines, yet we are only at less than one quarter of what we need overall. Meanwhile electricity is already extremely expensive over here. Reducing meat consumption is only easy if you don't like meat or like to castigate yourself. I personally would rather see Miami sink into the ocean than not eat as much meat anymore. And I know a majority of the population thinks this way. Now take the above and tell that to the inhabitants of an up-and-coming nation like China, Brazil, Nigeria or South Africa. They'll just laugh at you I guess. They want their piece of the cake, too.
