An American diver broke the record for deepest submarine dive ever and found something disheartening at the bottom of the ocean – a plastic bag. Victor Vescovo traveled seven miles down to the deepest part of the ocean, Mariana Trench in the Pacific, BBC News reports.
I can't imagine attempting to go that deep underwater. It has to be one of the scariest ventures possible. The darkness, the isolation, the sounds, the strange creatures... Yikes!
Human trash is in every nook and cranny on this planet. The human race and just about every species on this planet is now a walking, slithering or swimming toxic waste dump. This is our contribution to the planet.
thanks for the post.
deep-sea exploration fascinates me.
it is my opinion that inter-planetary space flight cannot be practical for humans
until we master living long-term in deep-sea environments where the survivable
conditions and rescue avenues are within current technology.
regarding the plastic bag....in outer space, we have already electromagnetically
and otherwise "polluted" near space enough so that allowances are made.
In another article, the guy talks about how enjoyable and peaceful it was gliding across the ocean floor. I have a fear of deep waters especially oceans and cannot imagine how petrified I would be going only a fraction of the depth he went to.
Dallas businessman Victor Vescovo became the deepest diving human in history when his Five Deeps Expedition reached the bottom of the Pacific Ocean's Challenger Deep on April 28, the expedition disclosed Monday.
100% fake news. Plastic does not sink to the bottom of the ocean. It floats on or near the surface.

OCEANOGRAPHY, RESEARCH 10 OCTOBER 2016 OCEAN PLASTIC MOSTLY NEAR SURFACE, STUDY SHOWS
It is a commonly held belief that plastic pollution is spread from ocean surface to seabed. Our newest study, published today in Nature Scientific Reports, shows that at least for buoyant plastic bigger than a sand grain (0.5mm), this is not the case, primarily residing on or near the surface. It also reveals that conventional methods to study ocean plastic underestimate microplastic loads by up to 97% due to ocean mixing processes that push part of the debris just below these sampling devices. Understanding how plastic is distributed in the ocean is important to assess its impact, and allows us to adequately dimension our ocean cleanup systems.
To summarize the main conclusions of the study:
Most buoyant plastic mass is within the top few meters of the ocean
The higher the wind speed, the more profound the mixing becomes
The type and shape of the plastic (fragment or piece of line) also has a large influence on the mixing
Standard plastic sampling devices (which skims only the top ~15 cm of the ocean surface) underestimates the amount of microplastic by a factor of between 1.04 and 30.
Microplastic concentrations decrease exponentially with depth, and approach zero within 5 meters of depth, regardless of the wind speed and particle type.
