Life on Earth walks by the ocean
Earth is not called a blue planet, without a reason. 71 percent of the surface of our Earth and 90 percent of the biosphere is the sea. It is essential for life and 50 to 80 percent of the oxygen present on the earth comes from here. This is very important for the carbon cycle. It is still not known when the ocean formed on Earth, but it is believed that it was formed about 4.4 billion years ago and he played the role of a catalyst in early life.
Secret of depth
Despite the huge size, we know very little about the ocean. In fact, more than 80 percent of the world’s hidden under water has not been investigated. Scientists are working on finding the hidden secrets in depth, which will probably help us to understand the changes in the environment. It will also be known how to manage the resources of the ocean in times of climate change.
Earth climate controller
We know that the seas play a big role in controlling the Earth’s climate. Now whether it is to absorb solar radiation, the distribution of temperature or the cycle of the weather. However, climate change has already started to disturb this balance. This is affecting the efficiency of the work related to the ecosystem of the ocean, such as storage of carbon and manufacture of oxygen.
Life in the ocean
At least 230,000 known creatures live in the ocean. Coral reefs like sea level crabs, starfish, snails as well as colorful reefs harbor fishes. Many types of vegetation pass through shallow depths. Sharks, whales, and dolphins make great habitats in deeper areas. That is, there is life on the foot of the ocean.
Strange and magnificent creatures
There is no surprise on the claim of scientists that more than two-thirds of the ocean organisms have not been discovered so far. Although researchers are getting some new creatures every year. Most of them have never been seen before. Now look at this squidworm. It was discovered in 2007 in Celebs Sea. Everyone can speculate about what else is yet to come.
Despite such vastness, the ocean is under pressure. The simplest example of this is the increasing incidence of coral reef cleaning worldwide. Due to the rising temperature and pollution, the coral is growing and the particular type of algae is going out from there. This algae allows them to grow and breed. In such a situation, only scary skeletons are left behind. Some corals can overcome this, but the risk of their death will increase if there is constant pressure.
Climate change is also affecting marine life. A recent research shows that local populations of fish, snails and crabs are disappearing twice as fast as the extinct creatures on Earth. The main reason for this is the rise in maximum temperature. If the heat increases in the ocean, where does one go to save? The sad part is that most sea creatures will not be able to adapt themselves to cope with the changing circumstances.
The part of the earth which is covered with solid water i.e. snow and ice is melting due to heat. Somewhere the snow is melting and somewhere the glacier. Due to the current melting, the sea level is increasing worldwide and the acidicness of the oceans is also increasing. This is due to the methane gas released from the permafrost of the Arctic Sea floor.
Man is very deeply attached to the sea. For thousands of years, human communities have lived on the seashore. They depend on him for food and employment. Today, more than one billion population lives in the lower coastal areas, which is going to be in danger due to rising sea level.
However, the cost of contact with humans has been paid by the seas. Only 13 percent of the world’s ocean area is such where human activities are not going on. There is no balance left in the area adjoining the coastal areas. Technically moving forward means that even remote areas of the Arctic Ocean are no longer untouched. Saving the remaining biobans will be a big challenge for the coming generations.
