Yes, this would be very easy compared with many other problems we are facing.
Our society in its current way relies a lot on cars. Far travels are not yet easily possible without planes. Electricity is not easily replaced (needs some time to build, we need batteries etc.). And we need to tackle all these problems and face the challenges that come with it. But food is so easy. We just need to change some optics of food. We wouldn't even lose any nutritional value (we would even gain so many health advantages) but people insist on having tortured animals in their food instead of the same nutrients and taste provided by plants.
So maybe stop listening to what they say. Start going to the streets and make them listen to us.
