To survive, humans have taken possession of part of the land and made use of animals. While this was likely necessary for the species to survive, human development has likely rendered this situation unnecessary and undesirable.
Indeed, continuous growth is reaching its limit in terms of how wellness is improved by appropriating more resources and using more animals. We are also starting to realize that caring about animals and nature provides us with positive feelings of recognition and empathy. Besides, it provides the chance for adventure and surprises when observing them in their natural environment.
Consequently, humans should cease the unfair use of animals and divide resources equitably. The manner in which they should be divided is open to debate, but here are some general considerations. For one, wildlife requires large and safe spaces in which to feel free. Second, some parts of wildlife are dangerous and need to be protected from. Third, human needs should be accounted for with as limited an impact on wildlife as possible.
An interesting proposal would be to distribute the land and have humans use a certain proportion of it (for instance, 20-30% over time). This reserved space would become human hubs, which would be separated from the wild land by fences but would include doors to allow passage of humans to wild lands. Furthermore, these human hubs would be connected by means of transportation, which would allow for free and safe passage as transparent as possible for wildlife.
Of course, that would not protect against insects and birds, which humans have already become partly accustomed to and will have to be dealt with later. Also, currently owned animals would either be released into the wild, with the inherent risk of being free until a natural balance is re-established, or their reproduction would be limited.
Humans could also take a role to make wildlife feel better in a greener nature with shelters and access to potable water.
This general proposal can be seen as a long-term target to reach, and each of our short-term actions can help us get there faster.
