There exist various effects and laws like the peaks of pyramid effect, the cultural source effect, the ecological butterfly effect, the law of value gradient distribution, and the inverse law of diminishing marginal utility. The Himalayas are the "Shenque"(which is believed to be the most secret and crucial acupoint for humans) of the Earth, and the "brain" of human beings. We must make the protection of the Himalayas a common task for all humans and establish the theory that the area around Mount Qomolangma should be regarded as the model and base of green development. The ten countries around Mount Qomolangma should build a partnership for green development and take a green lowcarbon path for sustainable development.展开更多
