The cake next to your name is a lie. I don't believe it's your birthday :P

I think that wavy line is a river. Those 3 bars are pipes and those fires are symbols for chemical industries.
So the symbol shows that chemical industries are pumping wastewater into the rivers. A really important message I think.
Don't trink stream water by the side of wastewater pipes kids!

Happy Cake Day!!
