As we keep pumping carbon dioxide into the atmosphere, more of it is dissolving in the oceans, leading to drastic changes in the water's chemistry. Triona McGrath researches this process, known as ocean acidification, and in this talk she takes us for a dive into an oceanographer's world. Learn more about how the "evil twin of climate change" is impacting the ocean — and the life that depends on it.

Plastics are durable, light and versatile. However, they take up to 400 years to decompose. This will affect people’s lives for the next 16 generations.
Our excessive use of plastics is impacting ocean health and biodiversity. By 2050, there could be more plastics in the ocean than fish by weight.
Humans make a lot of noise! Transportation, industries, & how we work and play in natural spaces all have an impact on the sound we put out every day, and all this noise pollution is disrupting how animals use sound to communicate.

Our topic for today is Water Pollution.
Contamination of water by harmful substances, which affects life on earth, is termed as water pollution.
Due to human activities, our water is getting more and more polluted day by day.
Household garbage is disposed into various sources of water.
Many people perform their domestic activities like bathing, washing clothes and utensils, etc. in these sources of water.
Also, industrial wastes are discharged into the water, leading to water pollution.
Consumption of this polluted water leads to diseases like cholera, typhoid, diarrhoea, etc. in human beings.
Polluted water also adversely affects the aquatic life.
Thus, we need to make sure that we do not pollute water.
Domestic activities such as bathing, washing clothes and utensils should not be done in rivers, lakes, ponds, etc.
Household garbage should not be disposed in the various sources of water.
Also, sewage and industrial waste water should be treated before discharging into the water.
Today we're investigating the many different ways the ocean has been polluted, using a book I've been reading lately, The Swarm by Frank Schatzing, as my guide!
Join me in the wonderful world of dumping all your problems into the ocean, where nuclear submarine, mustard gas, sulfuric acid, and heaps and heaps of trash are only the tip of the iceberg.

Sources / Further Reading:
Pollution is an alteration of the environment, natural or due to enthronization, by polluting elements. It produces temporary discomfort, disease or permanent damage to life in a given area, and can place the area in imbalance with existing natural cycles. The alteration can be of different origins, chemical or physical.
A judge ruled Wednesday that Arkansas-based Tyson Foods, among several other poultry companies, were responsible for pollution from chicken waste in Oklahoma.

The comet makes impact in spectacular fashion, destroying the Eastern Seaboard of the United States.
Mimi Leder (The Peacemaker) directed this science-fiction disaster drama about the possible extinction of human life after a comet is discovered headed toward Earth with the collision only one year away. Ambitious MSNBC reporter Jenny Lerner (Tea Leoni) stumbles onto the story, prompting a White House press conference. United States President Beck (Morgan Freeman) announces the government's solution: a team of astronauts will travel to the comet and destroy it. The team leader aboard the spaceship Messiah is Spurgeon Tanner (Robert Duvall), who was once the last man to walk on the moon. However, the mission fails, splitting off a chunk of the comet, now due to land in the Atlantic with the impact sending a 350-foot tidal wave flooding 650 miles inland, destroying New York and other cities. The larger part of the comet, hitting in Canada, will trigger an E.L.E. (Extinction Level Event), not unlike a "nuclear winter" as dust clouds block out the sun and bring life to an end. President Beck reveals Plan B: a cavernous underground retreat constructed to hold one million Americans, with most to be selected through a national lottery. Since teenage amateur astronomer Leo Biederman (Elijah Wood) discovered the comet, his family gets a pass to enter the cave, but his girlfriend Sarah (Leelee Sobieski) and her parents will be left behind. Meanwhile, still in space, Spurgeon Tanner devises a plan for a kamikaze-styled operation that could possibly save the Earth. Special visual effects by Scott Farrar and Industrial Light & Magic.

Earth’s history has been marked by five great extinction events. With the current background extinction rate 1000 times the normal, have humans brought about the 6th mass extinction? The changes our species has wrought upon Earth, its ecology & climate, has led geologists to compare us to a geological force akin to volcanoes, and terming this era the Anthropocene period (“Anthropo” meaning ‘human’). Will it witness the greatest loss of biodiversity ever? What does the fast-changing climate mean for the future of humans? Experts weigh in on these questions in this documentary.

Why are we being hit with so many asteroids? Could we survive in underground bunkers? And how much damage would Jupiter’s gravity cause?

Whether you’re a trained archaeologist, an independent researcher or just somebody with a passing interest in history, Google Earth really is an incredible research tool. We can view any part of the world in superb detail and the satellite pictures that make up this interactive globe are updated year after year – sometimes twice a year – and as well as seeing the planet as it appears today, we can also scroll back through the archive, and compare different parts of the planet through time.
The great thing about Google Earth is that its accessible to everyone – we can all get involved – and there is a growing community of researchers on Twitter. I have a friend who runs a Twitter account called ‘Globespotter’ and it’s because of his account I’m making this video.
Watch this video to learn more about spotting ancient, historic and natural anomalies on Google Earth, and how to become a 'Globe Spotter' yourself.

New observations of our atmosphere calculate that it extends far beyond what we thought, encompassing the moon! This means that we've actually never left Earth's atmosphere. Here's what else these observations can tell us.
A Dead Satellite Is Unlocking The Secrets Lurking Beneath Antarctica - https://youtu.be/Qck8zPUS3Is
Earth's Atmosphere Stretches Out To The Moon - And Beyond
"The new study revealed that sunlight compresses hydrogen atoms in the geocorona on Earth’s dayside, and also produces a region of enhanced density on the night side. The denser dayside region of hydrogen is still rather sparse, with just 70 atoms per cubic centimeter at 60 000 kilometers above Earth’s surface, and about 0.2 atoms at the Moon’s distance."
The edge of space: Revisiting the Karman Line
"A number of these authors suggest that the large variations with time of atmospheric properties make it futile to locate a true boundary of space based on physical arguments. In this paper I will argue the contrary: there is a moderately-well-defined boundary of space, it coincides with the Karman line as originally defined, and that line is close to 80 km, not 100 km."
Exosphere - overview
"Not all scientists agree that the exosphere is really a part of the atmosphere. Some scientists consider the thermosphere the uppermost part of Earth's atmosphere and think that the exosphere is really just part of space. However, other scientists do consider the exosphere part of our planet's atmosphere."

Exoplanets That Might Be Better Than Earth
► Subscribe: https://goo.gl/r5jd1F
Scientists have been finding exoplanets that could be potentially habitable
for some time now. There are hundreds of millions of them out there, and more found every day. There isn’t a planet like ours anywhere in the universe that we know of. But now scientists say they have found exoplanets that could be more habitable than the Earth… but do they really exist?
We are on social media:
From the highest mountains to the deepest rivers, this blockbuster series takes you on an unforgettable journey through the daily struggle for survival in Earth's most extreme habitats. Planet Earth takes you to places you have never seen before, to experience sights you may never experience anywhere else.
