Trends in Environmental Science

[Sonal Gadhave]

Dear All,

I would like to know how to chose a topic for PhD in Environmental Science?

I know my topic of Interest i.e marine environment & Hydroponic plants. I sorted few topics and many of them were related to energy, botany etc and seniors said me that it doesn't comes directly in Environmental Science, but still its bit confusing that what comes exactly in Environmental Science as it is combination of all sciences .

It would be very helpful if some one help me out sorting current needs & trends of research in our field.

Select Bio-remediation / Bio-transformation of contaminated sites and use Hydroponic plants
