Increasing carbon dioxide levels get a lot of press for creating environmental problems in the atmosphere, but that’s not the only place the higher-than-normal amounts can cause problems. Ocean waters are becoming more acidic as they absorb more and more carbon dioxide from the atmosphere. Certain chemicals in seawater normally dampen the sound waves by absorbing the energy from sound into chemical reactions. More carbon dioxide means less of these chemical reactions, so sound will not be absorbed as readily. Sounds will then travel farther and be louder than normal at a given distance.

This can create problems for some sea animals that use sound to communicate with each other and find their prey. Dolphins are one group of sea mammals that depend on sounds.  If there are a lot of residual noises from ships and sonar, they might have problems finding food, or finding each other to regroup. Researchers will continue to study this phenomenon to see if problems develop. It might actually turn out to be a benefit, if they are able to locate each other from farther away. Time will tell, but hopefully in the meantime we can figure out how to reduce our carbon emissions and help out a bit that way.

“More CO2 Could Create A Racket in the Oceans”

Sinornithosaurus, a raptor with bird-like features, was discovered in China in 1999. Recently researchers have been examining the remains in more detail, and have figured out that these dinosaurs most likely had a system for injecting poison into their prey. There are grooves in their teeth and a duct running along the base of the teeth. A small cavity in the skull would have been the spot where a venom-producing gland was held, which then fed poison into the ducts and down the teeth. The raptor mostly likely held its prey for awhile until the poison was able to immobilize it, then feasted on whatever it had caught.

“Add Venom to Arsenal Of Dinosaurs on the Hunt”

It’s great to take a metaphorical stroll around the ethernet, just to see what’s up in environmental-related blog articles. I thought I’d share some links that may be of interest:

First, some good news from India about an environmental group that was able to convince officials not to build a neutrino observatory in an elephant corridor.

Next, A National Geographic Moment about aphids, ants, and a bird.

Then, if you’d like a simple metaphor that can help you understand global warming, read this.

Finally, something you can do: some Green Grocery Shopping with reusable bags – even the veggie bags!

Large dairy farms with many cows will also have large amounts of manure to handle. One farm, called Wildcat Dairy, is so large that some of the 40 employees do nothing but deal with manure all day, every day. The cows leave their stalls to go get milked, and while they’re gone the workers come and clean out the stalls. There’s a concrete alley that collects the waste, but some solids in the stalls need to be pushed out to the alleys. The tank-pump, towed by a tractor, collects the waste in the alleys. The waste gets sprayed on a field to dry, and once it’s dry enough it will be spread on fields where crops will be grown. These crops are then fed to the cows, who produce the milk and more manure. And so the cycle continues.

On the Farm, a Cycle of Waste That Does Not End

Above is an example of a very short condensed article that will appear in the first newsletter of Noah’s Ark Wetlands Foundation. Part of our core mandate is to educate schoolchildren, to bring awareness about environmental science and the natural world, and we’ll do that by providing a monthly newsletter with a number of articles of varying lengths. This should give them a taste of what’s available to know about environmental issues and beauties and innovations.
