My whole idea for assignment 2

Maybe some of you remember my symbol is about asid rain but in assignment 2 its seem like i change my area of global warming is deforestation.The truth is,asid rain is also connected to tree,asid rain will slowly effect the natural that is tree or jungle.

Firstly,i have two sketches for assignment 2,first is a building that is been destroy by the asid rain

second,a tree that mean we must protect nature from asid rain (pollution)

Lastly,i took the positive not the negative side that is the tree.

That is the reason why i choose to pick to draw the tree.
