Exploring Oceans: Arctic

The coldest, windiest place on Earth holds 60 percent of the fresh water on the planet. Recent expeditions to the Weddell Sea produced more than 700 new species, including giant carnivorous sponges.

It really makes you think twice about what we are actually doing to this world. Destroying its natural beauty.

lets just hope the earth is in a cycle.

i am informing that i will use a part of this video in a project of mine.

@ciaopertutti Согласен.Запад должен отступить.

Fantastic video...:-)

Руки прочь от Арктики. Северный полюс - РУССКИЙ! (по праву первенства). И Антарктида, кстати тоже принадлежит России, так как открыта была русскими мореплавателями. По-честному, следовало бы ещё пиндосов (американцев) визами обложить для выхода на околоземную орбиту и космическое пространство. Не заплатили пошлину - сбивать их спутники нафиг. Это всё-таки русские люди первооткрыватели Космоса. Так что идут все в жопу! России чужого не надо, России своё защитить.

Whether one believes global warming is real or not, why shouldn't we practice good environmental stewardship anyway? There's no such thing as "a nature that we are hurting" because we're honestly not a separate entity ~ WE ARE NATURE. Anything we're doing that's 'environmentally unfriendly' bounces back at us in some way or another~ take dead zones in the Chesapeake for example; when we cause them we're not only killing fish, BUT WE'RE KILLING FISHERIES. No fish = no fishing. No fishing = broke.

@tim79338 it seems were splitting hairs and i think we should just agree to disagree :)

[tim79338]

@psmanici4 think you missed something...  guess it depends on how well your courses were. can't really blame you if someone taught you a bunch of crap. however, maybe you just weren't paying attention. between gravity holds all these gases you are talking about in. even if some are seeping out, it's very minuet and is still replaced... because we do live in a closed system. maybe you should take more classes to where they reach that part in your studies.

[psmanici4]

@tim79338 after studying physical and inorganic chemistry at university, i do not require a description of a closed system or photosynthesis/ aerobic respiration. Light gaseous elements do not remain on the planet- mars used to have an atmosphere but it dissipated into space millions of years ago. Planet earth is not a closed system. Energy and matter enter in the form of radiation and meteorties etc, and leave through radiation and gravity field escape.

[tim79338]

@psmanici4 'closed system' basically means nothing in, or out. Kinda like how we use Oxygen gas and give of Carbon Dioxide... and in return, vegetation takes in carbon dioxide and gives off oxygen. doesn't really have anything to do with energy or temperature. All elements remain on this planet even though compounds may change (chemical reactions) and be used. The planet recycles practically everything on it's own.
