Is there a need for Civil Engineers in the future?

Yes, absolutely. They innovate and will often be needed. As an example, oil, coal and gas extraction (hydrocarbons) are going to be with us for the next 50 years at least. This industry requires chemical engineering expertise. Detergents and environmentally friendly versions for clothes washing, dish washing etc require chemical plants to produce. These require chemical engineers to design, build, operate and improve upon. There are many other examples too.
