Start Recycling Today
Start Recycling Today
Recycling is like exercising – everyone knows we should do it, but not all of us do it as frequently as we should and many of us don’t do it at all. However, there are tons of reasons why you must make an effort to recycle as much as feasible. If you have not been diligent about recycling, this article provides some great reasons why you should start.
1. Recycling cuts back on global warming.
2. Production of certain materials from the start can release serious amounts of CO2 into the atmosphere.
3. Recycling paper saves trees – for each ton of paper recycled, 17 trees are saved. Each of these trees can extract around 250 pounds of carbon-dioxide from the air in a year.
4. Recycling makes us more energy-efficient. It frequently takes a great amount more energy to form something from nothing than to reuse it.
5. It keeps our landfills from overflowing. We are fast running out of space for landfills especially near towns.
Beach towns have been dumping trash into their seas for years to by-pass the difficulty, but with widespread sea ecological collapse, this isn’t longer a practicable option. Worse yet, it’s hard to find land in suburban and agricultural areas whose residents will permit landfills to come into their areas without a fight. The squeeze for rubbish heap land is only going to become worse in the future.
Recycling gives us some hope. Studies show that 60% to 75% of rubbish in landfills can be recycled. That suggests that if everyone recycled, we would have 60% to 75% less rubbish in our landfills, and we’d need at least that far less land for rubbish disposal. The rubbish in landfills is mostly not treated in any way it’s simply thrown in a huge hole and buried over. A lot of this rubbish isn’t environmentally friendly or readily biodegradable and it is unsurprising that contaminants can get into our water. It is also a major reason why it isn’t safe to drink from streams and brooks when you are hiking and camping even when it’s like you are in a spotless environment. It reduces air pollution. A lot of factories that produce plastics, metals, and paper products release poisons into the air.
For instance, plastics are usually burned in incinerators. Plastics are made with oil, and that oil is released into the atmosphere when the plastic burns, creating significant greenhouse-gas emissions. From manufacturing to processing, from collection to invention it’s common knowledge that recycling is an expansion industry, earning billions of bucks yearly. Our desire to recycle is only going to grow more insistent as populations grow and as technology changes. It adds to property worth. It is obvious a rubbish heap near your house can decrease your property values significantly. Recycling decreases the quantity of land required for landfills. This decreases the quantity of homes near landfills, keeping property values up and house owners cheerful. The more folks recycle, the less landfills we need and if enough folks pitch in, recycling should pay off for everyone. It is good business. Pitting business against the environment is a lose-lose situation – everyone suffers.
Commercial factories and processing plants save masses of cash on energy and extraction systems when they use recycled materials rather than virgin resources. They also make sure that basic resources don’t become a scanty commodity, keeping demand and costs down and making sure that their business can continue for years to come. One person can contribute. Many of us think this is true with recycling, too but the reality is that small acts of recycling make a giant difference.

Antarctic Peninsula Climate
Antarctic Peninsula Climate
Antarctic Peninsula has been experiencing warming trends for over 40 years with an increase of 2-3 C, thus correlating with lower sea ice conditions in the Amundsen Sea and Bellinghausen Sea. Warming temperatures around the Antarctic Peninsula is changing the dynamics of the ecosystem. The rise in atmospheric temperature is causing increasing in melting of freshwater glaciers and ice shelves. Fresh water emerging into the sea counteracts the salinity within a regional area. Changes identified are;
• Decrease in sea water salinity up to 60 miles offshore
• Lower sea ice
• Decreased krill population
• Increased salp (open ocean tunicate that is reminiscent of a jelly-fish) population
• Increase in cryptophytes (single cell phytoplankton algae)
• Decrease in diatom phytoplankton
• Increase in carbon sequestering in deep ocean sinks
• Decrease in carbon availability in the food chain
The Antarctic Krill (Euphausia superba), a small shrimp like crustacean is the most important zooplankton species associated with the sea ice and plays a crucial role in the Antarctic food web. On a regional basis the amount of krill appear to be declining in the southern ocean. There are definitely lower trends in krill population during lower sea ice years around Antarctica. Part of the rational for the population decline is that ice algae rely on the sea ice for protection and growth. The krill need the sea ice in order to feed on the algae and phytoplankton.
Krill occur in groups or large swarms. They are less than 3 inches in size and feed primarily on phytoplankton and sea ice algae. Krill filter diatom phytoplankton out of the water column and scrape algae from the sea ice. Apart from frequenting the sea ice to feed, krill in particular juveniles, seek protection from predators in the many nooks and crannies formed by the deformed sea ice floes. Krill is the staple food of many fish, birds and mammals in the Southern Ocean. The biomass of Antarctic krill is considered to be larger than that of the earth’s human population.
Sea- ice algae utilizes atmospheric carbon dioxide for its energy source, the same as plants do on land. Krill diet of the sea-ice algae and phytoplankton is essential for converting the carbon for use in higher animals such as fish, birds, and whales. This carbon conversion is a very critical role in predatory nutrition. Additionally krill do eliminate some of the silica from the diatom shells and carbon in sticky balls that sinks nearly two miles into the deep ocean. These cold, deep waters are able to contain carbon dioxide and prevent the gas from rising to the surface, thus immobilizing carbon that is not passed into the food chain.
In recent years there have been increases in algae phytoplankton called cryptophytes. Mark Moline, California Polytechnic State University, states that the cryptophyte population correlates with warmer temperatures and lower salinity waters that are produced by the melting of the freshwater glacier. Cryptophytes measure around 2 mm, while other plankton in the Antarctic waters are much larger and measure 15 to 270 mm. Along with the increase in cryptophyte population an increase in salp, a pelagic tunicate, population has also occurred. There are differences between salps and krill. Salps feeding efficiency is capable of grazing on smaller food sources less than 4mm, whereas, the Antarctic Krill efficiency declines on any food less than 20 mm. The salps compete with krill for the phytoplankton and thus decrease the krill population. Additionally the salps feed on krill larvae, which also cause a decline in krill numbers.
The warming trend in the Antarctic Peninsula is showing a pattern of increasing cryptophytes over other phytoplankton and the increase in the salp. This influence is due to the low sea ice and the lowering of the salinity in the seawater. Salps and cryptophytes do better in the lower salinity, while the krill and other plankton are unable to tolerate the increased freshwater regime from the glacier ice melts. This selectivity gives preference to the salps as the dominant species while decreasing krill abundance. During lower sea ice seasons the density of krill declines while the salp population increases.
Carbon sequestering into the deep ocean from the algae and phytoplankton occur by both the salp and krill. Both species eliminate the atmospheric carbon received from the primary producing algae by producing fecal pellets by the salps and sticky balls by the krill, thereby, reducing the amount of carbon dioxide in the atmosphere. The salps though sequester more carbon into the cold deep ocean than the krill. However, the krill provides the most efficient pathway for carbon transfer up into the food chain. The cryptophyte dominated waters are less efficient in the food chain due to increased feeding by salps and the difficulty of the krill to utilize the cryptophytes as a food source. Migration patterns by penguins are changing, in part due to the changing krill population. Krill is a mainstay diet for penguins, and if the krill population changes, many other ecological changes occur with it.

Earthday Business on Your Mind?
Earthday Business on Your Mind?
The sun is shining across the hills of West Cork as I listen to the story of Earthday told by a team of evangelists with nothing but Earthday business on their minds. In 2008, visionary Simon Ford started a group to bring like-minded, positive people together in socially conscious activities. He called the group Social Traffic and right now that group has Earthday business on its mind.
The group’s first major campaign centers around Earth Day with an event named, Earthday Birthday a global birthday party for Mother Earth. Earthday 2009 and the celebrations that will go with it is all set to clamor its way across the social media landscape like some all embracing vine, covering the sometimes harsh elements of the online world with a softer, greener facade which many hope will last for more than a lifetime.
Earthday 2009 is a global celebration and a day to spread awareness of people’s destructive impact on the planet. But before you jump right in there and start changing the world on a massive scale here’s a few simple things you can do to make a difference right now, tomorrow and every single day after that.
Here’s my list of top five things to do to celebrate Earthday 2009 and reduce your impact on our planet;
1. Plant a tree or two. If you’re feeling energetic plant a whole field full.
A tree will absorb CO2 and other forms of pollution, provide a home to hundreds of creatures, help to create and retain soil and performs a whole host of other ecological functions. And, in case you needed a reminder, will leave a lasting legacy of your time on the planet.
2. Walk to work for a day, a week or a whole month. You’ll feel better and the earth will be a much healthier place to live too.
You might even want to think about joining a car sharing scheme and make it a permanent part of your work life balance to drive to work only one day a week and sleep the other four in the passenger seat while someone else does all the hard work!
3. Dry your dishes naturally. Turn off the dishwasher at the dryer stage of the cycle and leave your plates and cutlery to dry themselves for a change!
4. Turn off all your plug sockets before bed. Maybe spend the evening in the dark for one day a week and treat the kids to a few ghost stories before bedtime!
5. Don’t be a water importer.
Get rid of your supply of bottled water, keep a jug of fresh tap water in the fridge and reduce the damage we do to the environment by producing plastic bottles to hold gallons of mineral water that tastes no different to the clear, fresh water that is piped through your home.
So, if you’ve got business on your mind this Earthday, perhaps you should take a few minutes to look around you and realise how precious our planet is and how beautiful that small piece of turf is right outside your window.
If you want to know more about this subject and how you can make a difference take a look at this great squidoo lens all about Earth Day Birthday right now.
