The art works are about the beautiful natural scenes but covered by gray .They signified that our nature is being contaminated by human race more and more .The destruction like this is too serious to be beared and even contributes our marvelous nature to a complete dark world .Then what our next day would be what our future would be
Stop polluting !I hope that we take action at once ,because action brings out transformation .It is everyone's duty to protect the environment ,in this way ,we can create another new world .
