The spirit of the tree

The magical mangroves have given birthto thousands of lives. The canopy is a transit point and gas station formigrating birds. Tree roots are ideal places for marine life to thrive. At thesame time, mangroves are also natural marine protection forests, naturalbarriers to inland, and even "coast guards" for mankind. Let usprotect the mangroves together and feel the beauty of creatures and themysteries of nature.

The Explanation for myPainting

in the Topic of Mangrove Tree

In themiddle of the painting there is a mangrove tree, and at its left there arecouple other mangrove trees, in the water around their roots there are fishes.I think it’s not hard to see that thetrees and the fishes are personified. Mangrove trees are crying and shouting,and the middle-mangrove tree is holding a purple handkerchief. Why are theylooks so sad? Because except the main tree the rest of the trees aredisappearing, they forced to go away, and the disappearing trees are themiddle-tree’s family! The reasons which cause their vanishment, are us, humanbeings. Because we didn’t protect them well, thus, make them now disappearquickly, and I guess if now mangrove trees can talk and have hands, they mayhave this scene every day. The “damages”, the dark brown things on their tree trunks and roots are causedby pollution, all sorts of pollution, insects, diseases etc. again it’s because our lack of protection for them. The greenthings on their roots are seaweeds. In the water there have oil spill, abovethe water there are having air pollution which have an evil-looking face with it. Above the water atright there is a people’s hand which has through a new garbage. The fishes havetheir own world and cities too. Under the water, the fishes who aredragging their colorful suitcase and wearing backpacks on their back are not ona vacation, they did this are because their home, the roots of the vanishingtrees are disappearing so they are forced to leave. The eight fishes (who areat the right top near the spilling oil and that “guarding fish”) are goingto work, basketball coach is coaching the young fishes in the clearing. Around that clearing there have asmall grocery, a mall (with “sell” and “fruit” sighs there) and a slide. Downto the right bottom corner there is a middle school with a library. It’s in themorning, the kids are going to the school, some were in the school bus, someare walking to school and some are in their own car. At the very bottom of thispainting there have a fish who is picking and clearing the rubbish. Also therehave lots of other people’s garbage and fishes’garbage, sadly the trashes harmed fishes a lot--there have a poor little fishwith a trash which traded its head made it wounded. At the left bottom corner,there was a gas station which is made by the old carpet and rusty iron pipes.

Not onlyin this painting has the “Mangrove trees are the home of fishes” and “the Mangrove trees are polluted by us”, these two simple connections, butthere still have some other connections between the trees, fishes and people inthis painting. First one, this is the one I have already mentioned, and it isthe easiest one to comprehend, is that we are polluting the world and thisharmed the Mangrove trees and the fishes who had their homes around the trees.Second one, the fishes now are human beings, they are driving their shell-madecar, making their foods (this could form some smoke, people can think this is asmall factory), and throwing garbage everywhere, and if the people who watchthe painting closely they may see that there have smokes coming out from thefishes houses and cars, and there have a little fish near the gas station isthrowing the trashes. This meaning wants to show that we are polluting ourworld. Third one, this one have mixed the first two meaning to gather, thismeaning means, or what I want to show is that if we still harming our planetlike fishes harming their trees like what I have shown in this painting, oneday we will be forced to leave our lovely home, Earth, like the fishes wasforced to leave their home. What makes it even worse, is that if we pollutedthe world badly and the day we need to leave our home in not very distant infuture, and if that day come we didn’t have the ability to leave this planet wewill become extinct in the universe. Not one want this happen, so at last Iwant to say that we must doing something we to make this world have lesspollution. This is what my painting wants to show, thanks.

How can we survive and develop with mangroves in the future?Not only to encourage people of all ages to understand the well-being ofmangroves to the earth, but also to protect it while truly using the servicesthat mangroves can provide, such as observing its biological nature, readingrelated books, trying fishing and boating and other entertainment, so that morepeople can participate in the planning and construction of mangroves.
