This is my last stage of the poster..

1) I had change my TREE, and i use some SPECIAL method to draw it. Don't worry, it is full of leave on the TREE.
Trees and humankind have always had a symbiotic relationship. Since they evolved, trees have had a great influence on the shaping of the ecology of our planet. By means of photosynthesis the leaves combine the water and salts with carbon dioxide from the air to produce the nutrients which feed the tree. In this process, as well as trees create many chemicals, seeds and fruit of great utility to man. Trees also remove carbon dioxide, the main greenhouse gas, from the air.
However, growing populations and increasing development slowly changed the face of the earth. The forested area of the earth is steadily being depleted. This is leading to the degradation of the environment and the extinction of many species. There is now a real danger that in the not very distant future man will destroy a large proportion of the present population of species on earth, create an uninhabitable environment, and then eventually die out.
Therefore, it is important that we conserve our mother nature so that our younger generation does not have to live in a world without greens.
1) And now, i also use pen tool to trace out the land which beside the river by using graphic style panel for choosing the color of the land.
2) And use the pen tool also, trace out the river, and color it by using graphic style panel tool.
Global warming is a term use to describe a gradual increase in the earth’s average ground and atmospheric temperatures across the whole planet. Measurements indicate that the global temperature has increased by about 1 degree Fahrenheit in the past century. This warming trend appeared during a period when human activities were beginning to increase the carbon dioxide (CO2) and other greenhouse gases in the atmosphere.
Although most scientists believe that a rise in carbon dioxide emissions will lead to further global warming, uncertainties remain about the timing and severity of resulting climatic change. Nevertheless, many are convinced that human activities are partly responsible for the long-term warming of the past century and that climatic changes caused by greenhouse gas increases will be a continuing part of our future. Thus, human have the chance to undo or lessen the effect of global warming by changing their lifestyles.
The “reborned” earth without global warming is represented by a seed with newly grown leaves. The water droplets above the plant as well as the sunlight in the background signify the importance of both these elements in its growth. Overall, the symbol shows a new lease of hope on earth and human has the ability to improve the situation. This can be achieved by maintaining a balanced state between nature and human-made development.
As opposed to the common symbol which always show a grim representation of global warming, this symbol gives a more optimistic viewpoint of the whole situation. It has a more encouraging effect and thus will convey the meaning better.
