The images above are both meaningful and instructive: this man’s hard work is not only forhis own benefit, but also for the benefit of future generations.

The pictures serve to remind us that the existence of our current happiness and valuablenational heritage is due to the struggles of our predecessors.

We, in turn, should also work hard in order to guarantee the comfort and safety ofgenerations to come. Sustainable development has become a topic of heated debate in recentyears. While it is justifiable to satisfy current demands, we cannot neglect the needs of ourdescendants in the process. Our children also depend on Earth’s natural resources and weshould not deprive them of such necessities.

Unfortunately, many people only think of their short?term, personal interests. An entireforest might be clear?cut, in the interest of making a profit, without a single tree planted in itsplace. This inconsiderate attitude towards the welfare of our descendants, as well theindifference to the outcome of such reckless actions, can only turn Earth into a cold andlifeless planet. People must be taught to appreciate Earth as not only their home, but also thehome of our children and grandchildren, as well as all other plants and animals.

While making great efforts to increase our current quality of life, we must simultaneouslyconsider how our actions will affect future lives.
