There is no number 1 problem. Given the diverse nature of problems and the inpredictability of science, you cannot rank problems like that.
This.
It would be nice if we perfected the art of growing tissues and organs in a dish, though. Aside from organ transplants without immunosuppression, we'd also gain beef without cow burps!
Society could be collapsing around their ears but to an elected politician the biggest problem is how to get reelected. Science thinks much the same way; how to retain control of the 'problems' to ensure the flow of money, position, and reputation.
I will repeat (ad nauseum) this anecdote. My city surrounds a once beautiful lake. It is now a smelly mess due to the DNR's management program which promotes the growth of weeds all along its shoreline (to the consternation of lakefront owners who must put up with the smell and weedy mess, which often prevents them from launching their watercraft). The University Limnology Department attracts huge research grants to study biological communities that only occur in hyper-eutrophic waters, a condition that is scrupulously maintained. They conspire with the DNR to ensure that the lake remains a smelly mess, for if it were cleaned up this money would stop flowing (no one is going to pay to study a 'clean' lake).
So you often have the fox guarding the henhouse. There is often more profit in the 'problem' than in the 'solution'.
So one anecdote is "often".
BTW, to my knowledge, weeds along the lakeshore have nothing whatsoever to do with eutrophication. Eutrophication is caused by excess nutrients, such as fertilisers or just good old crap. Weeds along the shoreline are probably more likely to
mitigate the problem than cause it, since they will a) use nutrients themselves, b) stop soil from eroding into the lake.
Also, is this Lake Mendota we're talking about? The one that could
take hundreds of years to recover because the
soil all around it is still overloaded with phosphorus?
And does the guy who wrote that paper keep saying that you've
got to do something about the soil because he doesn't want to clean up the lake? Since the soil
is a huge source of excess phosphorus, that would seem like shooting yourself in the foot if your aim is to
preserve the eutrophic state of the lake.
Not only that, but in
this document by the UW Madison folks (the grant proposal for
this project by the looks of it), one of the objectives is the following:
Question 2: How can thresholds for transport and recycling of [phosphorus] be manipulated to mitigate eutrophication, or increase the resilience of clear-water lakes to eutrophication?
And further to that, the proposal explicitly states that the research will use historical data,
i.e. it no longer actually needs the lake to be gunky. The planned data source:
The Yahara lakes and watershed have been studied extensively for more than a century. From the wealth of ecological data available for this watershed-lake system (Brock 1985, Kitchell 1992, Lathrop et al. 2002), we will focus on data collected since 1976 by the Wisconsin Department of Natural Resources and the North Temperate Lakes Long-Term Ecological Research program funded by NSF (
Welcome to NTL-LTER | North Temperate Lakes).
And methodology:
Our approach employs two main strategies: (1) statistical analysis of long-term lake data, and (2) analysis of an integrated terrestrial-aquatic phosphorus model to explore linked landscape-lake biogeochemical and ecological processes. Both elements rely on existing data and the adaptation of existing modeling frameworks to the Yahara watershed-lake ecosystem.
Um, yes, I'm sure it's all a vast money-grabbing conspiracy. Or perhaps, just
perhaps, this is actually a tough environmental problem that doesn't have a quick and easy solution, and wanting to study eutrophic lake ecology has nothing to do with it.
