The qualities of human made environments, natural environments and cyber environments have all changed as humans evolve and the earth goes with them. Cities become larger as forests become smaller and the internet takes over the world in a short time in the near future but they all have a purpose.
Due to politics, economy and trade cities will definetly become larger and larger over time. All the big city owners and organizers will become power hungry, I can imagine, and will become greedy and cover too much land. due to the bigger birth rate at the moment and also immigrants coming in, in time the population will grow and with a greater population, there are greater demands and more resources are used such as fuel, food, trees and more.
So with more depends, power and gain, where is the say for the natural environment? well in fact the natural environment doesn't really have a say as it slowly withers away into the far reaches of the earth where man will never step foot. But seriously, due to demands, more trees will be cut down for building, forest will be cleared for new developments and more carbon emmisions will be released.
The Cyber Environment or 'Internet' will definetly change very quickly as it already has in the last 10 years of its arrival. I personally think that it will become more dangerous and easier for hackers to gain personnel information and other things. It won't be as safe anyway.
So as you can see the environment of everything will change no matter what we do. Life just works that way and so does the environment.
