But, from day to day, many book releas, little number of book which discussed about back to nature, keep save ecologist, and make better life for mother earth. Many book discussed abot physchology, money, bussiness, but, yups, so less of global warming topic I found.
-So difficult to invite more people be to realize that important if we are more care about this topic. But, we work to hard applied of the healthy life, economic, and of course to reduce impact of global warming. You may to buy much of technology, but you must to care about the recycle of that. Not only use, but also can recycle that. I know this posted look not gave the solution. I just to share what is in my mind, my hearth, to show another people, that important to keep more save the earth.
-Nowadays, buy a book is more expensive than some year before. And many amateur books was appear. Disappointed if books which buy isnt good, just looks the sensational title. So, in my concise of conclusion, how the books can be in change with ebook form. Like PDF file, so more be economic, practical, and more save paper to use for make a book, save our mother earth too.
