Do a google news search and they are prominent in the news.
I will say that there are no current stories on the Texas red tide, but there are stories on the Florida red tide. Its a little early in the season for red tide in texas.
And while you are at Google News, you should look at the recent stories covered extensively by the Florida media over the GOP politicians and Big Sugar. Big Sugar generates a lot of run-off pollution.
I'll give it to you briefly but it would take only 20-30 min to get all the details.
Big Sugar is paying for these GOPers to take free trips to the King Ranch in Texas, which is a high dollar hunting ranch. King Ranch is also in the Florida sugar business. So after all these stories run, Gov Scott, who also got a free trip, appointed this man from the King Ranch to a regulatory board in Florida. The short of it is Big Sugar doesn't clean up their pollution, the ratepayers and taxpayers have to pay for it.
Or in the case of the OK-ARK lawsuit I mentioned above, the ARK taxpayers had to pay the judgement that OK won, because ARK allows Tyson and the Tyson contract growers to pollute the river
And I guarantee you, this algae bloom in Lake Eire can be traced back to where it originated before it ran-off into the lake. But they won't do it.
In the US, most of the societal costs of pollution are not paid for by the polluter. Instead, they are externalized or socialized and society pays for them either in the rates they pay or the taxes they pay. There are also nuisance costs. The locals have to adjust their life to the negative impact.
First thing I suggest to quit getting news from places like Google or yahoo, these are LameStream Media personified with a biased axe to grind.
Back when the first Clean Water Act became law of the Land, I was a Pollution Control and Abatement Officer. Much of the pollution you claim was ceased by most companies, especially the big companies. It only took a few years of actually making a difference before the wildeyed inexperienced grads, who saw a deadly polluter in every company, gained control of pollution control. Still, the USA has some of the cleanest air and water compared to any country in the world.
Farmers, big and small, try very hard to not over fertilize. Why?, mainly because its their money running down the drain.
Now if you can show me there was no red tide before chemical fertilizer farming began, I might see some of it your way, otherwise you would be better off not seeing a nasty ol polluter behind every tree.
