what would happen if less and less girls get into engineering?

Hi Jennifer,
If less and less girls get into engineering, more and more girls would miss out on a wonderful career! I love being an engineer and making a difference in my job so I feel sad that some people rule themselves out from engineering because of their gender. 
From a business point of view there is research, backed up by evidence, to show that a better gender balance in a company results in better safety records and higher profits so businesses would also loose out by less girls doing engineering.
