Earth was an abundant, giving, benign planet that provided enough for everyone. Then there was civilization, and numerous discoveries and inventions were made. With these discoveries began a whole new life and lifestyle. Everyone was content, everyone happy. But soon enough, people wanted more. "Life should be simpler", they thought. More inventions were made, easier ways to survive, discovered. All was merry until one day people realized that there wasn't enough to go around anymore. Life was getting tougher again. Water was scarce, and there was no electricity for convenience. The dishwasher wouldn't work, nor would the washing machine. People had to resort to manual labor again. They had come a full circle, but this was a circle that would end, soon. There was simply not enough to go around anymore.
This is how it began, and this is how it will end. With the rate at which we are depleting the environment and all that it has to offer, not much is going to be left to survive on. We can't even think of our coming generations, it's our own survival we have to worry about. For this we need to learn how to save our environment, by unlearning some of the things we have become habituated to and taken for granted.
