What Year Will plastic take over?
Enormous amount of plastic will fill oceans, land by 2040 even with immediate global action, report says. More than 1.3 billion tons of plastic waste will flow into the world's oceans and land over the next two decades without widespread intervention, according to a new report.
What if fish went extinct?
The ocean will no longer be able to perform many of its essential functions, leading to a lower quality of life . People will starve as they lose one of their main food sources. The effects of a world without fish in the sea would be felt by everyone.
Will the ocean ever run out of water?
In reality, the world won't run out of water . Water does not leave Earth, nor does it come from space. The amount of water the world has is the same amount of water we've always had. However, we could run out of usable water, or at least see a drop to very low reserves.

The best estimates by scientists place the number of fish in the ocean at 3,500,000,000,000 .
Do fishes sleep?
While fish do not sleep in the same way that land mammals sleep, most fish do rest . Research shows that fish may reduce their activity and metabolism while remaining alert to danger. Some fish float in place, some wedge themselves into a secure spot in the mud or coral, and some even locate a suitable nest.

Are the oceans empty?
The sea is a flat, homogeneous space that appears empty . This myth of the empty sea is largely the product of European imperialisms and their map-making traditions in which the sea becomes blank space across which power can be projected. Just like more familiar myths of empty land, uninhabited and ready for the taking.
What will happen to the ocean in 2050?
Experts say that by 2050 there may be more plastic than fish in the sea, or perhaps only plastic left. Others say 90% of our coral reefs may be dead, waves of mass marine extinction may be unleashed, and our seas may be left overheated, acidified and lacking oxygen .
Will the oceans be empty in 2050?
Despite being treated as humanity's rubbish dump for decades, the oceans of the world are proving remarkably resilient, says a new scientific review. Building on that resilience could lead to a full recovery within three decades, the researchers argue.
How old is the ocean?
The ocean formed billions of years ago .
At this time, about 3.8 billion years ago, the water condensed into rain which filled the basins that we now know as our world ocean.

How much waste ends up in the ocean?
At least 14 million tons of plastic end up in the ocean every year , and plastic makes up 80% of all marine debris found from surface waters to deep-sea sediments. Marine species ingest or are entangled by plastic debris, which causes severe injuries and death.
Who invented plastic?
Belgian chemist and clever marketeer Leo Baekeland pioneered the first fully synthetic plastic in 1907.
How much plastic is in the earth?
Globally to date, there is about 8.3 billion tons of plastic in the world – some 6.3 billion tons of that is trash. Imagine 55 million jumbo jets and that's how much plastic exists here. In 1950, we created 2 million tons a year, which increased 200-fold by 2015.
How long until our ocean dies?
According to study seafood could be extinct in the next 30 years . A study from an international team of ecologists and economists have predicted that by 2048 we could see completely fishless oceans. The cause: disappearance of species due to overfishing, pollution, habitat loss and climate change.
What happens if the ocean dries up?
The oceans are gone, but we still have some water. ... Without clouds forming over the ocean, rain would be incredibly rare, and the planet would become desert . We'd watch our lakes and water supplies dwindle a little more every year until nothing was left. Humans might survive for a while near our homes.
How deep does the ocean go down?
The average depth of the ocean is about 3,688 meters (12,100 feet) .

How old is the water we drink?
The water you drink may be composed of the same water molecules that have been around since life started on this earth 4.6 billion years ago . We could be drinking the same water dinosaurs swam in millions of years ago.
Does the earth lose water to space?
It is not actual water what is lost to space , because in the high atmosphere water usually dissociate into other molecules or ions. The oxygen ion outflow is frequently assumed to be a proxy for the loss of water from the planetary atmosphere.
Does the earth make new water?
“ Today the atmosphere is rich in oxygen, which reacts with both hydrogen and deuterium to recreate water , which falls back to the Earth's surface. So the vast bulk of the water on Earth is held in a closed system that prevents the planet from gradually drying out.”
