Toxic Algae Threatens Florida's Gulf Coast 99
As reported by Discovery News, After Toledo had to temporarily ban residents from using tap water last weekend because of a toxic algae bloom on Lake Erie, you probably figured that we’d filled the quota of bad algae-related news for the summer. No such luck, unfortunately. Off the Gulf Coast of Florida, the biggest red tide bloom seen in Florida in nearly a decade already has killed thousands of fish. The bloom, which contains the microorganism Karenia brevis,
may pose a public health threat to Floridians if it washes ashore, which is expected to happen in the next two weeks, according to Reuters.
NBC News says this is the largest such bloom seen since 2006 — approximately 50 x 80 miles.

Unlikely. Fertilizer runoff from farms being dumped in a body of water will help algae growth, that's a very large part of what happened in Ohio, because apparently farmers in Ohio are fucking retards who think dumping manure on fields that are FROZEN OVER is a good idea and that it won't just all wash out into the lake there.
Petroleum isn't going to have the same effect by a long shot. There is no algae that eats oil.

The fertilizers used on lawns is blamed for the red tide outbreaks by feeding the organisms, it is believed.
Not to mention that most people (pro landscapers included) dump a lot more phosphorus than is necessary. A mature lawn needs very little phosphorus fertilizer, and in most areas none at all because the soil has enough. Using a phosphorus free fertilizer, which still contains the nutrients the plant needs such as nitrogen and potassium, is sufficient in most areas. And yet, general purpose fertilizer is often used (flowers and fruit needs phosphorus), and even fertilizer marketed for lawns usually unnecessarily contains fertilizer. And that's all about marketing and distribution. The fertilizer companies want to produce stuff they can market everywhere. Additionally, what are most people who don't know anybody going to buy, the fertilizer that says "27-3-10" or the one that says "27-0-10." The former of course, because 3 is better than 0! And lots of "lawn food" products contain plenty just for good measure without even having the N-P-K ratio on the label.
Education in this area would go a loooong way. Educate the public, the professional landscapers, and the fertilizer suppliers. There are even some municipalities where it's illegal to dump phosphorus containing fertilizer on lawns. Yes, it's easy to get away with breaking that ordinance (especially with the pretty labels at Home Depot), but what having the ordnance does in particular is educate the landscapers who will then buy phosphorus free fertilizer, which will in turn educate (to some degree) the public, and make phosphorus free fertilizer more available and the de facto standard.

I don't get artificial turf as a "green" alternative. If you just stop applying chemicals, and keep applying water you still have a lawn. It's just not a monoculture lawn. One place I lived in my college years did this out of sheer laziness, not a desire to be "green". This was in Virginia. Result? A lawn with some residual turf grass, but visually dominated by flowering clover, dandelion, some purple flowers I never learned the name of the whole time I grew up there, and a smattering of less common wildflowers. That was what survived the occasional mowing to about six inches. It was absolutely beautiful and when my Dad come down one weekend I told him that. He said what you'd expect from any post-war suburban parent: "Weeds".
Sheesh. I never did get that. Dandelion is actually useful. It's edible for cryin' out loud. Clover fixed nitrogen. Turf grass? I'm hard pressed to think of a use.
Anyway, I digress. I don't get the whole idea of covering the grass with a petroleum product. Just stop applying chemicals, keep watering if there's not a drought, and mow to six inches. Let nature take it's course, and explain be the change you want to see--owner of diverse, healthy lawns.

The reef's in the Caribbean and mediterranean were already heavily damaged when Jack Cousteau was swimming around taking notes in the 60's. Since then Science has discovered that a healthy reef actually has the majority of its biomass stored in large fish such as sharks, a severely degraded reef has the majority of its biomass stored in small fast growing invertebrates and weeds. The only reason the filthy Ganges river has not destroyed the Seychelles and other pristine reefs nearby is that it's mouth is clogged with thousands of acres of mangroves that act as a natural (and extremely efficient) water filter.
Nearly all marine biologists will tell you the answer to the serious problem of collapsing fisheries is to set aside marine parks in specific locations that would cover approximately 5% of the world's coastline and some specific deep sea ridges, virtually everyone else will say there's "plenty of fish in the sea".
