Extreme Weather
 
Highly reliable global temperature measurements show the planet is warming and the water cycle (hydrological cycle) is becoming more active; creating higher rates of evaporation and precipitation. Droughts and floods are the natural consequences of warmer temperatures: droughts because it’s hotter, floods because warmer seas release more water vapor.

DEET in our Waterways
 
The Minnesota Department of Health has placed DEET on the top spot on its list of "chemicals of emerging concern" and will conduct numerous tests this year. The main objective of the research will be to calculate a "safe" level of exposure. Although DEET has been okayed for clothes and skin (in moderation) it has never been meant for consumption. But with its increasing popularity and abundant usage it is showing up in ever greater quantities in our rivers, streams and lakes and it is only a matter of time before it shows up in our drinking water as well.
How The Average American Uses Energy
 
The average U.S. American consumes 335.9 million BTUs per year, the world per person average is 72.4 million BTUs. 48.2% of US electricity comes from coal. Only 3.7% comes from solar, wind, and geothermal. The average U.S. American uses 441 gallons of gas for their car each year... and more...
DECT Phone Safety
 
Radiation from cell phones has been getting a lot of press of late but according to the BioInitiative Report cordless phones look to be just as deadly as cell phones when it comes to brain tumors and acoustic neuromas. DECT technology originated in Europe and has since been widely introduced throughout the world. Today more than 800 million DECT systems are in use. The pulsed frequencies of the radiation used in DECT technology are in the microwave band. The ICNIRP is responsible for monitoring and creating guidelines for radiation technologies. The ICNIRP guidelines focus exclusively on high frequency radiation and thermal activity. But many scientists have been pointing out that pulsed microwaves at low frequencies are also cause for alarm.
BP Oil Spill
 
It is somewhat ironic that an extensive environmental study in the Gulf carried out by the Minerals Management Service, that counted and noted habitat preferences of cetaceans (marine mammals with a blowhole for breathing- including whales, porpoises and dolphins) encountered two species (melon-headed whales and fraser's dolphins) that were rarely seen in the area before... During the study the ship heard and saw numerous sperm whales in the vicinity of the Deepwater Horizon. There is a native population of about 1400 sperm whales that live in the Gulf of Mexico year round. And scientists say if we lose just a few of them due to this spill, it could dangerously tip their numbers into the negative. See many more photos here- of native cetaceans and the Gulf dilemma....
Is spring arriving earlier?
 
A new study out of the UK, published by the Royal Society, shows that flowers are blooming 2 to 12 days earlier than they did 25 years ago. The study used 400,000 records of first blooms, and looked at over 400 species of flowers. The research showed this pattern of early blooming to be the first in recorded history. The study also showed that a 1 degree Celsius change, over a short two year period, resulted in an earlier flowering time of five days. An earlier British study "Rapid Changes in Flowering Time in British Plants" (Fitter, 2002) showed that 385 plant species bloomed 4 and a half days earlier during the 1990s than the 4 decades prior. And yet another study out of the UK, by the Centre for Ecology and Hydrology found that in 2005, species were breeding on average 11.7 days earlier than in 1976. In the U.S....
Organic vegetables start out as seed...
 
For the past year there has been an uproar in the vegetable seed business as Monsanto has purchased Seminis (a seed conglomerate that has 40% of the U.S. vegetable seed market) and De Ruiter Seeds. Monsanto is now in the vegetable seed business for the first time and it's in big time. 55 percent of store bought lettuce, 75 percent of U.S. tomatoes, and 85 percent of peppers now originate through Monsanto's fingers. If you wish to steer clear of purchasing Monsanto seed- you need to do a bit of homework, as even reputable seed companies that have signed the Safe Seed Pledge, are still selling Seminis (now Monsanto) seed. Buying seed from a seed exchange, buying open-pollinated and organic are safe ways to avoid Monsanto seed.

Wheel like Honeywell Wind Turbine
 
This August Honeywell will release its 6 foot diameter gear-less (therefore lightweight) rooftop wind turbine that operates at wind speeds of 2-42 mph. Honeywell claims it will produce 2000 kWh/yr in class 3 winds and 2752 kWh/yr in class 4 winds at 33'. By eliminating the central gear shaft and using the blade tips to produce the energy Honeywell has created a turbine that can start producing energy at an amazingly low 2 mph.

A Reorganization of the Seas
by Marisa Baxbaum


    Evidence is mounting that our seafood preferences are causing a vast shift in the composition of aquatic ecosystems. Unless the developed world can curb its appetite for big fish – species such as tuna, cod, swordfish, marlin, grouper, haddock, sharks, and skate – these creatures will soon exist only in biology textbooks and Hemingway novels.

Threatened by overfishing. Illustration by Richard Ellis ram.biology.dal.ca



     Globally, fish comprises 12% of our per capita calorie intake. In 2006, 76 million tons of commercial seafood – or seven trillion individual fish – were caught and consumed. Industrial fishing practices have become so effective that numbers of predator fish, like the ones pictured above, are dwindling. Using historical data on catch rates from 1880 to 2007, scientists at the University of British Columbia found that populations of predatory fish across the globe have declined by two thirds in the past 100 years – with 54% of that decline occurring over the past four decades. This 2011 study follows another published in 2003, which concluded that industrial fishing has eliminated 90% of large ocean fish.^ As a consequence, as fishing efficiency has gone up, catch rates have gone down; only one successful catch is made per 100 longline hooks, as opposed to 10 per 100 at the onset of industrialized fishing technologies. Those fish that are lucky enough to avoid the longlines and gillnets are not numerous enough to reproduce sustainably. While UBC researchers do not foresee a totally fishless ocean by 2050, they do predict a massive ecological reorganization: without predator controls on the population growth of prey fish, oceans will be inhabited mostly by smaller species. Already, numbers of these prey fish have more than doubled over the past century, following the decline of their natural enemies. Although in some locales, such as the North Atlantic, herring and other small fish are in jeapordy due to unmonitored midwater trawling.^ And in the Pacific, populations of sardine, anchovy and herring are being taken in ever increasing numbers to feed cats, dogs, chicken and the growing numbers of farmed fish.*




ecosystem overfishing



     This is cause for concern, as big predator species are vital to ecosystem balance.^ Without predatory fish, we can likely look forward to murkier, less diverse waters. As populations of certain small, foraging fish increase, so does the incidence of algal blooms. This is because the small foragers eat zooplankton, which in turn consume algae. The loss of predator fish may thus precipitate a deep green sea, robbed of oxygen by these suffocating algal blooms and rendered uninhabitable to most aquatic organisms.


     Climate change, in conjunction with overfishing, will also pose a threat to ecosystem vitality. Heavier rainfall, predicted to occur mostly in tropical areas, may form a surface layer of warmer, fresher water that does not mix well with the denser, colder, and saltier layers below it. This stratification of the water column inhibits the circulation of deep water nutrients, which plankton – the base of the marine food chain – need to survive. Fewer plankton means less food for fish, affecting species growth all the way up the food web. Another problematic factor is ocean acidification, caused by higher levels of dissolved CO2 in the water. Coupled with warming, acidification may put excess stress on fish and further limit their growth. Those species that simply cannot handle the changes can be expected to move to more habitable waters. This includes over 50% of our current stocks, which may relocate by up to 40 kilometers per decade.


     Sharks – of which 100 million are harvested yearly – are needed to maintain healthy seagrass beds and coral reefs through similar food web mechanisms that keep foragers in check.^ But since shark fins are a delicacy than can fetch up to $500 per pound, the economics of the trade are outweighing the need for conservation efforts. Only three species out of 350 – the white, whale, and basking sharks – are actually protected from the international fishing trade, and the fishing process itself is both cruel and wasteful: once the fins are removed, the shark is usually tossed overboard to slowly die. Sadly, sharks are now as endangered as they are unfairly demonized: they constitute the largest group of threatened marine animals on the World Conservation Union’s Red List.

     Even though their flesh accumulates higher levels of toxic mercury and other contaminants, it’s the big, predator fish that are preferred on our dinner plates. Industrialized fishing practices have enabled our oceanic scouring, but these practices cannot be blamed any more than increasing dietary demand. Fifty percent of that demand increase can be attributed to East Asian countries, and 42% of that to China. Western nations are also guilty. In Britain, native waters are so overfished that restaurants and household kitchens must rely on imports six months out of the year.^ The depleted state of 70% of U.S. fisheries prompted Congress to tighten federal catch limits in 2006, but fish stocks are still in jeopardy as of 2011:

     Unless demand lessens and stricter regulations are imposed on the fishing industry, predator fish – and the ecosystems they help support – will have little chance for recovery. The continued existence of wild oceans depends on our willingness to change our palates. For links to more sustainable seafood choices, see: inspirationgreen.com/fish-seafood-guides
