Life of all human beings and animals really relies on nature around them. In these nature pictures, all amazing landscapes may truly not avoid appreciating such this nature and its covered planet. Note that life depends on nature, but the nature seems not to rely on the life. Based on beautiful pictures and scene, environment strongly relies on nature; when the nature declines, the environment exactly decreases. Thus, climate change may be due to environment degradation and this is a consequent declining of nature.
In seeing of several nature photos, the landscape seems to be not damaged by human beings, but this is only to make assumption. In images, we may not estimate of how much they are ruined and how much they are remained. We just only give some ideas that they are beautiful scenery images indeed, and they should be continued to preserve and conserve if they are not ruined. To preserve nature first becomes duty of all people on the planet, but the word of duty should be moved from this term to obligation, otherwise we may not see anymore such beautiful nature.
Note that it is really true in the planet if we do not care about nature, in adversely effect the nature will not serve the planet. As a result, life on the earth may jeopardize any time. For instance, a case of dropping fresh water on the planet may be a clue of decreasing agricultural products; this may lead to starve human beings indeed. So, the care, the conservation and the protection of the nature will become more important for us to pay attention; otherwise the new generation will blame us and the blame may pass from one generation to another.
