Dear Harshini
Due to vast increase in all engineering colleges, there are so many students who are opting ECE/CSE etc.., but they're not upyo the mark in their studies and also when compared earlier now the atmosphere is getting too worse. So our government encouraging studnets
To opt environment courses like you've mentioned and the scope will be too good in the upcoming years. I wish you go opt the environment engineering, if youre passionate about it.
A the best, but take wise decision.
