Ships in the Desert

While I shipped in the Aral Sea, I thought it should be called a desert sea as it looked more a dry sand’s sea than the fourth largest inland sea in the world. Then on my trip to South Pole, I learnt the butterfly reaction that a small reduction in one country’s emissions could changed the remotest and least accessible place’s environment. I also found that global warming was obviously in polar. I learnt from scientists that many general natural phenomena had been changed, such as the spring snowmelt now comes earlier every year; the temperatures of Polar Regions rise, etc.

Some of the most disturbing images of environment destruction can be found in many places.

At the equator in Brazil, the Amazon rain forests are been burned or cut for other uses. The air is filled with billowing clouds of smoke; the green plants disappear; thousands of rare birds become extinct. In high northern latitudes, on some nights, the sky itself shows a ghostly image named “noctilucent cloud” which signals the loss of ecological balance now in progress. Then, how should we human beings face these images of environment damages? Should we take actions to save our environment or ignore it?

However, if we human want to respond appropriately to these distressing images, it is better to classify these environment threats firstly. And we should classify them in a global context.

General speaking, there are tow major classifications. One is the not

truly strategic threats, which be considered in two ways: essentially local in nature and fundamentally regional; one is the fundamentally strategic threats, which also could be seen in two aspects.

The great increase in the amount of chlorine all over the world is a strategic threat. And if we let chlorine levels continue to increase, all animal and plant life will face a new threat to their survival.

Global warming is also a strategic threat. The increasing concentration of carbon dioxide and the heat-absorbing molecules in turn determine the distribution of vegetative and animal life on land and sea and have a great effect on the location and pattern of human societies.

Human civilization is now the dominant cause of the dramatic changes in the global environment. It works in two key factors: a sudden and startling surge in human population (now, the world population will increase from 2 to more than 9million); a sudden acceleration of the scientific and technological revolution (more new and important discoveries have taken place in the last ten years than in the entire previous history of science). These two factors results from human civilization and they result in the changes of nature balance. Then it turns on the new relationship between human civilization and the earth’s natural balance.

The greatest challenge is from military. And the eventual solution to the arms race lies in new understandings and in a mutual transformation of the relationship itself. The key changes of this transformation will be in the way we

think about the institution of warfare and about the relationship between states. This can only be accomplished by undertaking a careful reassessment of all the factors that led to the relatively recent dramatic change in the relationship.
