With the population of the world growing and doesn't seem to be stopping, something is going to have to budge, whether it be us or the world and it's probably going to be the world. Over population is an another issue raised in the book, because of the world's population, millions of forests had to be cleared for crops to be grown so large amounts of chemicals where dumped on forests to kill them quicker and easier. Pollution is the main problem in the book. Diana's parents keep on saying that chemicals poisoned the lake because it has a funny tinge to it and shouldn't be drinking or used to grow food.
Although the book refers to how much the world has suffered so much, the main character always try to keep an optimistic mind, an example of this is where Diana believes that there is a city on the moon where people retreated to when the word started to die. She believes strongly in this because she was told this over and over when she was a child and she needed hope, something to hang on to.
In my own opinion, I believe that we are doomed. Now I"m not one of those people who think everything is bad, my opinion is based purely and utterly on facts. A prime example is global warming, with the depleting ozone layer due to chemicals such as CFC's, it's warming the planet up at an alarming rate. With the warming of the planet comes the melting of the ice caps and that raise's the water levels around the world. Although this is happening slowly, already 10 pacific islands have been lost and the natives have had to move of there island which they have owned for centuries. But this is becoming a bigger effect because some countries are thinking about lifting the no CFC ban because that it cost's too much and some companies will go out of business. Now let's think about this for a second, saving the planet and stop the depleting ozone layer and losing a couple of companies. Or slowly yet surly destroying the planet from heat and then in time, we would end up like the "red planet" and keeping some big pointless company that we already have millions of in the world.
