I tried to be optimistic that once the people will consider the importance of conserving the nature. But when the term “the people” is derivated into “persons”, one by one, my optimism went away. For example, even when knowing the real danger of smoking to their body and their family, some persons still insisted on smoking, and wished to the smoke that everything would be all right. Now I think that’s what we have done so far: destroying the nature and the society, while expecting everything to be improved.
