First of all, as words are a poor channel of which I can express my thoughts, I will define what I mean by the worlds humanity and nature. Humanity will refer to the human race, I will also use the term to encompass objects that humans have created and the changes we have caused to the environment. Here, humans shall be seen as something other than an animal. Nature refers to anything not manufactured or shaped by human hands, in other words, the state of the environment before humans had started changing it.
Humans are indeed destroying the world at an increasing rate. What I think is required is that we find a balance between development and the maintenance of the natural world.
Indeed there is some sort of imbalance upon the world; humans are taking over, almost suffocating the natural world with the advances in our own world. I believe that somehow a balance can be reached where humans have a place in nature, not as wild beasts and not as its protectors.
Try to see humanity and the natural world as two different substances inversely proportional to each other in magnitude. The larger our civilizations are, the less natural the world becomes. I think that it is possible to somehow maintain these two opposing forces in a fairly balanced manner.
It is important for us to remember to hold back when we see that we are doing too much damage. The only thing is that it is difficult to see things in the proper perspective as certain desires such as greed cloud our judgment. We must constantly reevaluate how we are as a species is affecting the rest of the planet. I believe that if there is a God out there, this would be his way of maintaining the natural order of things, a harmony, that achieving this balance would somehow allow us our proper place in the world.
All the time, we are taught to keep expanding our horizons and challenging our minds, but I believe that thinking inside the box, within certain restraints, is becoming more and more challenging. Since our resources are finite, it is only common sense to make use of them the best way possible and to optimize their use, even if it is inconvenient and difficult. Preserving the environment would help us slow the destruction.
