amazing encounter with an adorable elephant seal pup
Bookmarked 606 weeks ago this young elephant seal is what039s known as a quotweanerquot -- recently weaned and about 2-3 months old i refer to it as quothequot but we really couldn039t be sure what the gender was scroll down for more info i was part of an expedition with cheesemans039 ecology safaris my second trip with them to antarctica the excellent cheesemans039 staff made sure that all expedition members understood and followed the rules for visiting this wilderness: no food no waste maintenance of distance from the wildlife and appropriate behavior around the animals we were directed and reminded that we should walk slowly at all times and not disturb or touch any of the wildlife on the islands and mainland of the antarctic peninsula the required distance is 30 feet 10 meters from a nesting colony of penguins or other birds and 15 feet 5 meters from quotloafingquot animals but if wildlife approaches you closer proximity is allowed there is no baiting feeding or approaching the animals to facilitate interaction with visitors all close interaction happens by chance and is initiated by the animal itself we landed at livingston island to observe a gentoo penguin colony and there were also adult elephant seals lounging on the beach i wasn039t expecting to see such a young elephant seal pup and that039s why i sat down to watch and photograph this little guy as soon as i saw him come onto the beach i was thrilled when he approached me none of us who were privileged by his company reached out to touch or pet him -- we let him touch us and interact with us and stay or leave as he wanted i think if we hadn039t had to go back to our ship when we did he would have stayed there and taken a long nap next to usthis encounter was a high point of an amazing expedition that included the falkland islands south georgia island and the antarctic peninsula information about cheesemans039 ecology safari expeditions around the world is available at: wwwcheesemanscom my husband039s fine art photography from this and from an earlier trip to the southern ocean can be seen at: wwwstevegouldphotographycomi was using a canon vixia hf m500 camcorder with an external rode microphone this video was edited with premiere elements 11for licensingusage please contact: licensingatjukinmediacom |

water reclamation and reuse: the bluehouse solution
Bookmarked 731 weeks ago water: it039s everywhereor is it from the clothes we wear to the energy we use to the goods and services we consume daily water is the hidden resource we constantly depend on to maintain and enhance our lives we are currently consuming too much water too quickly for this natural resource to continue to adequately supply our needs americans use more than 400 billion gallons of water in a single day that039s more than our total oil consumption in a year we need to introduce new ideas and technological innovations to teach the next generation how to curb and better manage our water consumption we need to move beyond conserving and start reusing our water think about it quotis the storm water rainwater and sanitary water that leaves our homes office buildings or campuses a waste or an untapped resourcequotthe bluehouse offers an innovative solution to reduce our water demand the bluehouse can intercept what is today considered a waste and use what tomorrow will be considered a valuable resource the bluehouse treats water through a natural process for onsite reuse in boilers and cooling towers machining and industrial processes irrigation and even toilet flushing treating and reusing water with a system that is co-located on-site significantly reduces the amount of time and cost compared to adding massive infrastructure to existing municipal systems to complete the same function the bluehouse039s innovative design features an odorless lush greenhouse that uses the world039s first systematic application of reactor-based complex adaptive ecosystems this breakthrough technology has enabled sustainable water to change the look and feel of water treatment and reuse altogether our patented design allows for turn-key installations in less than 4 months allowing for the rapid realization of the benefits of reclamation and reuse as an aesthetically-pleasing greenhouse the bluehouse can be sited in nearly any environment: urban or rural without adding any modification to the current plumbing and storm water infrastructurewhile the bluehouse was initially designed for municipal and industrial applications our modular design can also be universally applied at nearly any college or university airport resort military base or any place where large volumes of water can be safely and reliably reclaimed and reused the applicability options of our facility are virtually endless allowing for you to continue living your life the way you have been while reducing your water footprint by reusing water you will lower your water intake and output reduce your overall water costs lower the stress on our current water infrastructure and minimize the amount of harmful discharge the may be re-entering our environmentpopulation growth and climate change are altering the planet at a faster rate than expected water is the most important substance for life so it is imperative that we begin taking action the bluehouse is not a lifestyle change but it is a change in how we use water by taking the demand off of potable water supplies we can create a reliable resource minimize our stress on the natural environment and lower costs at the same time |
