It is hard to wait for the results of anything important, isn’t it? Elections, primaries, pregnancy tests, adoption referrals, job interviews…. ( my recent visitor from Option Adoption will agree, as will the expectant mom over at The Creamery–  two interesting blogs I’ve just started following.) I don’t even know when the staff will decide on who the next American Idol After School Teacher will be.
So let’s just talk about my recent visit to Manatee Park, shall we?

I was so lucky to have these two to assist me at all times. 

My girls and I saw so many manatees, and so close up. We rented a double kayak, and with Carla in the seat behind me, and Annie sitting in front of me, I paddled us around the Orange River somehow managing to steer the kayak, not capsize, and also take a bunch of pictures.

The red and black mangroves are a fascinating part of the ecosystem. 

Though manatees are very hard to photograph, I managed to capture a few bits and pieces. It was a beautiful experience.

And here’s the tail, just under our kayak. Curious little thing! 

I captured this tail flapping up out of the water using the zoom lens. 

While we were at the park, I was able to sit and listen to a park employee discuss facts about manatees, their habits and their ecosystem.  Manatees, also called sea cows, eat lots of different kinds of underwater grasses.  Like cows on the land, they have a specialized digestive system that is designed to break down the grasses.  Their digestive system works by employing a particular bacteria that can only break down the grasses at 68 degrees farenheit or warmer; if the manatee is in water that is colder than that, it will starve, even if its rumen is full of grass. These creatures have truly specific habitat requirements.

Annie, kickin’ back and enjoying the ride. 

I have been thinking a lot about cows and a farm’s ecosystem, because I’m still working my way through Michael Pollan’s The Omnivore’s Dilemma. 

There are quite a few words devoted to describing a way of farming that is sometimes known as “grass farming.”  Polyface Farm is described in detail as an example of this.  The grass takes in energy from the sun, and that is what fuels this kind of farm — grass which is then the food for the cows.  Chickens are the cleanup crew for the cows, as they wander the cow patty-studded grass eating up bugs that would otherwise be harmful.  The chickens leave just enough poop on the grasses to help fertilize the grass. The cows, who graze the grass in a careful pattern that does not chew it down so far that the grass dies, actually HELP the grass be healthy rather than harm it.

There’s much more to the this farm’s careful use of the land, and there are many more animals that contribute to the farm’s fertility.  What kept coming back to my mind as I considered the graceful sea cows was how the grass farmers are trying to mimic nature and its cycles.  I thought about this as I listened to the naturalist speak of the sea cows and how they have no natural predators, and how man was the their only threat to survival. Nature doesn’t just place an animal into a system without making it pay its way.

Cute little lizards are all over the place in Florida. 

I was certain that the sea cows must be serving some purpose there in the waters.  They are mowing the sea grass, keeping it healthy. But if humans continue to limit their habitat, I imagine that the manatees are in danger of over-grazing the grasses that they need to survive on.  In fact, much of the rivers where the manatee would graze no longer have healthy grasses for the manatee to enjoy, even as watercraft make those waters perilous for these gentle and slow mammals of the sea.

Humans have also messed up farmlands, using energy from fossil fuels to buy fertility and then use it up at a rate much faster than can be replenished.  Even natural grasslands get overgrazed and turned into deadlands.

Who are our natural predators? I think it’s becoming increasingly clear that we share something in common with the manatee: our biggest enemy is mankind, ourselves as we seem to be making our own habitat increasingly unsustainable. This makes me unbelievably sad.
