After being inspired by Gary Taxali I created some lino-prints symbolising renewable energy and specifically global warming and bio fuels. 

This design emphasises global warming an the fact that the Earth is getting hotter but if we start using renewable energy sources it could result in the decreases of global warming. So my design shows the Earth being too hot and using wind turbines as fans to cool itself down.

These two final designs with corn on them promote bio fuel, specifically using corn for fuel in cars.

These two designs promote wind power as a different source of energy which will result in reducing global warming
