Every Friday, MNA gathers news related to the environment from around the state and country. Here are a few highlights from what happened this week in environmental news:

Toledo water crisis passes but long term threat looms (Great Lakes Echo): Despite the scare and being unable to drink water, residents still found themselves apprehensive to drink Toledo tap water — despite Mayor Michael Collins drinking the water in front of them. Although there is no longer a ban on drinking the water, a larger problem prevails not only in northern Ohio communities but those along the Great Lakes Basin.

Behind Toledo’s water crisis: A long troubled Lake Erie (New York Times): Like the MNA post this past week about Lake Erie and damage of algal blooms, Michael Wines of the New York Times offers an in-depth look into the problem. The story tracks down the past of Lake Erie and discusses the trouble its faced in the past and how now scientists and government officials are taking serious concern to the issue due to the recent water crisis in Toledo.

6 Ways Nature is Inspiring Human Engineering (Forbes): Biomimetics, or the imitation of nature for the purpose of solving human problems, has led to new breakthroughs in technology. Researchers are looking at the eyes of moths to understand how their structure can be applied to solar technology as well as using spider silk for bulletproof vests.

Just how far will urban sprawl spread? (Conservation Magazine): The World Health Organization has predicted by 2050, 70 percent of the global population will reside in cities. This will inevitably increase urban sprawl — an issue that affects natural habitats and ecosystems worldwide.

Every Friday, MNA gathers news related to the environment from around the state and country. Here are a few highlights from what happened this week in environmental news:

Winged Wednesday: A Great Lakes summer bird guide (Great Lakes Echo): There are 47 million bird watchers in the nation over the age of 16, according to a 2011 U.S. Fish and Wildlife survey. With this nationwide trend, the Great Lakes State offers diverse habitats throughout both peninsulas, making it difficult for birdwatchers to pick a favorite location.

Peter Marler, graphic decoder of birdsong, dies at 86 (New York Times): Basic animal science in the 1950s made the claim that animals made noises very unlike human conversation. Yet, when Peter Marler, an animal behaviorist born in Britian, came along, he showed that songbirds learned to sign in varieties or dialects of their region.

White House pushes financial case for carbon rule (New York Times): According to an analysis by the White House Council of Economic Advisers released Tuesday, carbon emissions causing climate change could cost $150 billion per year. The report serves as another way to further Obama’s plan of cutting carbon emissions and reducing climate change.

Vicious cycle: Air conditioning is making your city even hotter (Conservation Magazine): Rising temperatures start creating a cycle of turning on the air conditioning, emitting carbon into the air and causing temperatures to continue to rise in the long run. Yet recent research has shown that air conditioners are also making temperatures hotter just through the absorption of hot air in a room and its emission outdoors.

Creating a prairie dog “Facebook” to aid conservation (Conservation Magazine): In recent studies, researchers have attempted to gain more insight into the social world of animals via “social network analysis.” This method in research has helped scientists to take a closer look into the complex social networks, hubs and connections of prairie dogs.

Lake Erie’s algal blooms: a cause for concern

In a story from the Great Lakes Echo, Lake Erie has yet again produced record-high algae blooms. In 2011, the amount was the worst ever recorded with 2013 coming in close.

Lake Erie has been used as a source of water for farming and drinking and the increasing toxicity poses harm to the environment.

According to Discovery News, algae blooms are a natural part in the life of an aging lake, but have been greatly increased due to human activity.

An explanation of algae

Algae are common members of aquatic communities. Often in the form of green plants like seaweed, these plants grow and are green because they contain chlorophyll. Algae usually doesn’t pose problems in bodies of water, but algae blooms are of greater concern. These green-blue scum masses are full of harmful cyanobacteria, containing threatening cyanotoxins.

The US Centers for Disease Control (CDC) defines cyanotoxins as “a diverse group of chemical substances that are categorized by their specific toxic effects. In humans, cyanotoxins can affect the nervous system, gastrointestinal system, liver and increase tumor growth.

The toxic dangers in Lake Erie

The problem facing Lake Erie is not only that it’s turning a pernicious green color, it’s under silent attack by toxins in water runoff making their way into the lake. Fertilizer from agricultural practices in recent years has contributed to this issue. Climate change may also be contributing to the issues surrounding Lake Erie, causing more storms, higher water temperatures and less control of fertilizer runoff.

Nutrients in the fertilizer runoff have contributed greatly to the growth of cyanobacteria, fertilizing the toxin rather than the intended on-land crops. Not only is this bacteria harmful for humans to consume in drinking water, it creates “dead zones” in different areas of lakes. A dead zone happens when the bacteria consumes most of the oxygen in a particular area of a lake, so that other organisms are deprived of that oxygen and die.

A plan of action 

In Michigan, scientists hope to continue monitoring the water, although the high amount of algae blooms has been a great cause of stress and concern. Recently, President Obama reauthorized a federal law which allocates $82 million for studying and monitoring algae blooms. This time, the Great Lakes were included.

 

Deer Lake cleanup success, Michiganders in favor of decreasing coal burning, Google searches educate on climate change: this week in environmental news

Every Friday, MNA gathers news related to the environment from around the state and country. Here are a few highlights from what happened this week in environmental news:

Michigan’s Deer Lake could be taken off polluted hot spot list (Great Lakes Echo): Deer Lake, located in Marquette County in the Upper Peninsula, has endured decades of costly cleanup which may soon pay off. The lake had been contaminated by mercury from nearby mines. Since the lake was listed as an area of concern in 1987, the restoration process has been well underway and Deer Lake could be taken off the polluted hot spot list in the next few months.

9 surprising diseases you can catch in the nation’s oceans (Huffington Post): Water affected by oil spills and chemical pollution may be making headlines, but those aren’t the only bodies of water being affected by contamination or disease. Find out the surprising diseases humans can catch just by swimming, swallowing water or breathing in mist at polluted beaches.

Michigan voters favor changing energy mix — especially if it doesn’t cost anything (Great Lakes Echo): A poll by Public Sector Consultants revealed that more than 42 percent of Michiganders would like to see the use of coal burning for electricity significantly reduced over the next 25 years. Still, in another poll conducted by Denno Research, only 13 percent would support drastic movement away from coal in the next decade, even if it were to mean rising costs of electricity.

Geothermal industry grows with help from oil and gas drilling (New York Times): Geothermal energy, a mostly forgotten way of harvesting energy, involves drilling into the ground and using the earth’s hot air for energy purposes. Despite being less than one percent in the world of ways to harvest energy, the United States is still the leader in this industry and it’s slowly growing.

Using Google tends to gauge climate change perception (Conservation Magazine): University of Rhode Island environmental researcher Corey Lang found that with more weather anomalies, there were more online searches about climate change. Particularly during hot summers, mild winters or long rain-free periods these searches seemed more apparent.
