Seven billion human beings live on planet Earth. But despite of our vast collective knowledge, the oceans remain a largely unknown territory even though they take up three fourth of our planet. We as humanity rely on the oceans for our very survival.
All life started in the ocean. We come from the ocean – 4 billions years ago from the colony of living fossils called Stramatalites. If it weren’t for the oceans we would not be here.
The movie “Planet Ocean” really helps understand the role of the oceans from the smallest plankton to the biggest whale.
You learn that Mackerels hibernate and that it takes a drop of water 1,000 years to complete its ocean current cycle.
Half of the world’s population lives less than 100 km from the sea and we rely on the sea to provide us with food, minerals, and other vital substances.
The movie tells what is happening with our oceans and put questions as to what is happening with mankind. Being against overfishing and killing off the life in the ocean is not enough. Much more radical action is needed right now.
Seeing Nature’s rich resources being robbed by us humans based on profit; if someone wants to build a house/a bridge they do it with no consideration to how it might destroy the marine biodiversity.
All countries are using the oceans to their own advantage. Bigger and bigger ships are built to overfish, we go deeper and deeper to drill for oil and we pollute the oceans so much that we have to make pools to swim in.
We are destroying the natural currents of the oceans. The five major ocean-wide gyres—the North Atlantic, South Atlantic, North Pacific, South Pacific, and Indian Ocean gyres. Each is flanked by a strong and narrow “western boundary current,” and a weak and broad “eastern boundary current”. The excess fresh water from the rapid melting of the Artic flushing the Oceans is changing the currents because this water is less dense than the salt water.
It is all about how the peoples of the world are grabbing to survive. We overfish the Anchovies in Chile turning them into fish fodder to feed the salmon dams in Norway.
Overfishing destroys the marine life because the nets catch all sizes; this also destroys the livelihood of the small fishing families.
Plankton is a crucial part of the cycle of life in the oceans. The changes in the temperature destroy this cycle. For every food chain there are plants to eat and without this the fish die or migrate to cooler waters where they can get the right food to eat.
Nature does not tolerate excess, it is always seeking for balance. We destroy this balance for example when tuna is overfished; small tuna are caught and overfed in dams to get lots of profit. Tuna consumes a lot of jellyfish so when we overfish tuna we get an overload of jellyfish because only few fishes can succumb the venom from the jellyfish.
Plastic pollution is killing birds, fish and other animals in the oceans because they mistake plastic for food. Twenty five blue whales stranded from the North Sea. When they were opened up – the stomachs were full of plastic – one even had swallowed a 40 feet fishingnet. So they died from starvation with full stomachs!
100.000 ships cross the oceans every day; 6 million containers transport things. We even transport forest. We have become the super predators. The Planet is ours. We have made the Suez and the Panama Channel to get better access to transportation. The oceans have brought us all the minerals we need in the world. The oceans offered us the possibility for Globalization.
Every second breath comes from the ocean. I am capable of understanding. I am becoming aware of my power. We have to return to the very beginning. The movements of the oceans are the source of all life. My drive has taken me a long way. How did I get to this point?
