The theme of our collage is environmental engineering. Mechanical engineers fit very well with this theme because starting from air pollution control device to solar cars and wind mills, everything falls under both mechanical and environmental engineering. In fact, the time has come when “ all engineers need to be environmental engineers” instead creating “ environmental problems” for environmental engineers to solve . Environmental problems are everybody’s problems & every body must share the responsibility to deal with it. This should be the way to go to save our grandchildren.
