We'd have actual rights and protections for non-human persons, for one. At present, my country has relatively little in the way of that. As such, the vital needs of non-human persons are often simply not considered at all and the non-vital needs of humans override the vital needs of non-humans on a routine basis. That is how we have so much habitat destruction in the first place - no consideration of the existinct ecosystem and the non-human persons who already live there, no real attempt to work together with them. Instead, just "getting rid of" them, like they are pests and reshaping the land to our own image and whims.
But there is so much messed up with how law is done in my country, it is difficult to even know where to begin. The "justice" system as a whole is far too punitive and not focused enough on recognizing we need to cooperate and connect with one another. To give back, not just take. To extend a hand to help, not just one to slap or hit. A few moons ago, there was a man who cut down one of the oldest trees of the state that was on public property. He claimed it was his, that he had a right to it. Did he plant trees of this species to give back? No. He just took. That's the kind of mentality that's the problem, in my view. He got punished with a fine because it was on state property. His "punishment" should've been planting more trees. Giving back, restoring what he took... even though that will take longer than his lifetime.
