what's the connection here?

Plants
-the good-
Think this:
carbon dioxide + water + light energy → glucose + oxygen + water
(and vice versa)
What about it? the CYCLE. photosynthesis[+]

Roof
-the bad-
ok...why bad? not good?
we need all these shades to protect us from the OH-SO-HOT SUN! wtf?!

Plastic bag
-the ugly-
is it only us, Malaysians? or what?
the ugly Malaysians who love to litter anywhere, anytime?

What do they represent?
Plants- the NORM of Nature. the carbon dioxide/ oxygen cycle.
Roof- the EFFECT. we now need protection.
Plastic bag- the CAUSE. because of he, she, them, u and i!

WHY?!?
please la people...
u know what you should do.
i've said enough. more than enough.

With love,
Jade
