That's like saying HR's budget is the same as Accounting's budget because they're both part of Incorporated Widgets, and that we should fire Bob in HR because Sandra is a good accountant. Doesn't make a whole lot of sense or reflect how these decisions are actually made. Funding more social sciences doesn't actually mean funding less other science, just like hiring an HR rep doesn't entail firing an accountant.

Different funds are appropriated for different purposes, funding the kind of research you're talking about would likely be connected to an NSF grant or a national lab. Note as well that science, like everything else, experiences diminishing returns. Putting 1000x the money into water treatment research won't get you 1000x the return. Allocating funds at the scale of the federal government isn't zero sum; you can saturate the amount of funding it's possible to provide, and it does make sense to spread funding around many different areas.

Incidentally, that research you want to see is probably in jeopardy because the grant funding it contains forbidden words like "environment."
