Natural resources...

One week ago, in class, when we were talking about natural recourses, I imagined our planet fifty years from today and I realize once again, how bad our energetic situation is. Everyday we do our routine and most of us don't even remember the huge quantity of natural recourses and energy that we daily spend. Since 17th century, society daily grows up her needs of natural recourses and consequentaly her pollution and natural impact are growing up too. First Industrial Revolution, then the car and recently the electricity, all these things are basics in our lifes and both spend a lot of natural recouses, namely, fossil fuels. As we know, fossil fuels became our first source of energ, but they are coming to an end. Experts say that we'll have fossil fuels just more fifty or sixty years. What then? How our life will be? I can't imagine my life without car and electricity and I'm sure that almost anyone can. On the other hand we can't just care about our needsm, we must must be worry with environment too. As we increase CO2 and CFC's emissons, most widely known gases, global warming and ozone depletion increase too and they are having very bad impacts in our lifes, like climate changes that we can see everyday. We must put a stop to this situation, using renewable recourses ( like sun and wind), recycling and sparing fossil fuels and non- renewable recourses. We just have one Earth , so, we must take care of it, if not, in the future we'll not have our "home" anymore.
