Which of the following will make it hard in the future to develop sustainable methods for humans using resources? There will be fewer renewable resources More humans will populate the Earth Biodiversity naturally reduces over time More humans will recycle materials

The answer would be more human will populate the earth. Be cause the more we populate the more our resources will run out. Think of it like animals in the wild. If there is an environment with wolves and rabbits and the wolf population increases. What will happen to all the rabbits? They will decrease the amount of resources for the wolves. But sense there will be limited rabbits the wolves will eventually decrease making the rabbits increase and this process will keep going on until one of them go extinct.
