The Conservation of the Seas handwritten newspaper reads as follows:
The ocean is one of the most important determinants of climate change on Earth. The ocean itself is the largest heat reservoir on the Earth's surface. Ocean currents are the largest conveyor belt of thermal energy on the Earth's surface.
The exchange of gases between the ocean and the air (most notably water vapour, carbon dioxide and methane) has a significant impact on climate change and development.
The ocean is the habitat of many plants and animals. Chlorella in the ocean is one of the main producers of atmospheric oxygen. Tropical coral reefs are the most species-rich ecosystems on the planet (even richer than tropical rainforests). Little is known about deep-sea creatures.
The ocean has many species of animals and plants that are not found on land, and there are many kinds of waves on the land, and the waves are constantly rolling on the sea, sometimes the waves are as flat as a mirror, and sometimes they are huge. With the exception of those caused by ** or volcanic eruptions, most of the waves are caused by winds blowing across the surface of the sea, and waves stirred up by distant storms may move hundreds of miles to reach the shore.
Before the development of aviation, navigation was the main mode of human transportation and travel across continents. The exploration of the deep seabed did not begin in earnest until the mid-20th century.
Although humans today explore the ocean with diving balls and submarines, little is known about the deep sea. Marine geologists in the depths of the earth have used laboratory simulations to find water at depths of more than 1,000 kilometers below the surface, where people least expect it.

Let's draw a simple and beautiful picture togetherUnderwater worldCopy the newspaper by hand
1. First draw a title at the top of the screen, and draw a small crab on the left side of the title.
2. Draw a seahorse on the right side of the title.
On the left side of the screen, small fish, octopus, bubbles and other elements are drawn.
The hand-copied newspaper of the underwater world is simple and beautiful.
3. Draw different small fish on the right side of the octopus, and the small fish spit bubbles.
4. Start coloring, paint different colors for small crabs, seahorses, small fish, and octopus.
5. Paint the title in a beautiful blue color to make the picture more complete.
6. Finally, add a grid line in the middle of the picture, and a hand-copied newspaper is completed, isn't it simple and beautiful?
What is written in the content of the underwater world hand-copied newspaper.
Sometimes we don't know what to write in the hand-copied newspaper after drawing it, but in fact, we can add content about underwater creatures to the hand-copied newspaper to make our hand-copied newspaper richer.
Benthos. 1. Blue whale, the blue whale is the largest animal in the world known to man, and its whole body is blue-gray. The largest blue whale catch is in 1904 in the Falkland Islands in the Atlantic Ocean.
Neighborhood. This blue whale is meters long and weighs 195 tons, which is equivalent to 35 elephants.
weight. 2. Killer whales.
Killer whales are bold and cunning, and they are brutal and gluttonous, and they are the "lawless **" in the vast ocean. The English name for killer whale is killing whale.
** meaning. Quite a few people have repeatedly witnessed killer whales attacking dolphins at sea.
A thrilling sight of sea lions as well as large cetaceans.
3. Dolphins, in the past, people used to say that monkeys are the most intelligent animals in the animal kingdom. But it turns out that dolphins are even smarter than monkeys. There are some skills that monkeys need to learn after hundreds of trainings, while dolphins only need more than two dozen to learn.
If the intelligence of an animal is measured by the percentage of its body weight by its brain, then dolphins are second only to humans, while monkeys are in third place.

The marine living environment is a complex system that includes seawater, seawater containment and suspended solids, seabed sediments and marine organisms. The abundant biological, mineral, chemical and power resources in the ocean are indispensable resources for mankind and are closely related to the survival and development of mankind.
At present, the main goal of marine conservation is to protect marine living resources from depletion for sustainable human use. Particular priority should be given to the protection of valuable and endangered marine life. According to a survey by the relevant departments of the United Nations, due to overfishing, accidental killing of marine organisms that are not allowed to be hunted by non-targets, engineering construction of coastal and tidal flats, felling of mangroves, and widespread pollution of the marine environment, at least 25 of the world's most valuable fishing grounds have been depleted, and many marine animals such as whales, sea turtles, and manatees are in danger of extinction.
It is expected that with the expansion of marine exploitation, there is a possibility of greater damage to marine living resources. The task of marine protection is first of all to stop the excessive use of marine biological resources, and secondly, to protect the habitats or habitats of marine organisms, especially the coasts, tidal flats, estuaries, and coral reefs where they migrate, spawn, feed, and avoid predators, and to prevent heavy metals, pesticides, petroleum, organic matter, and nutrients that are prone to eutrophication. Maintain the regeneration capacity of marine biological resources and the natural purification capacity of seawater, maintain the ecological balance of the ocean, and ensure the sustainable development and utilization of the ocean by human beings.

The ocean is the general name of the most extensive body of water on the earth, the central part of the ocean is called the ocean, and the edge part is called the sea, which communicates with each other to form a unified water body.
The earth's surface is divided by major landmasses into a vast body of water called the ocean, which has a total area of about 100 million square kilometers, accounting for about 71% of the earth's surface area, and an average water depth of about 3,795 meters. The oceans contain more than 1.35 billion cubic kilometres of water, about 97 per cent of the planet's total water, and only 2 per cent of it is available for human consumption.
Extended information: 1. Salt content.
The salt content of seawater in the world's oceans varies from place to place, but the average is about the most common of these inorganic salts dissolved in seawater, sodium chloride, i.e. table salt for daily use. Some of the salt comes from volcanoes at the bottom of the sea, but most of it comes from rocks in the earth's crust.
The rocks are weathered and disintegrate, releasing salts, which are then carried to the sea by the river. In the cycle of vaporization and condensation of seawater into water, the salts remain after the evaporation of seawater and gradually accumulate to their current concentrations. The oceans contain so much salt that they can spread up to 500 feet thick on the world's land.
2. Marine disasters.
Marine disasters mainly refer to sudden natural disasters such as storm surge disasters, huge wave disasters, sea ice disasters, sea fog disasters, gale disasters and tsunami disasters.
The main causes of marine disasters are strong atmospheric disturbances, such as tropical cyclones and extratropical cyclones. disturbances or abrupt changes in the state of the ocean water body itself; Submarine **, volcanic eruptions and their associated submarine landslides, ground fissures, etc. Marine natural disasters not only threaten the sea and the coast, but also endanger the urban and rural economy and the safety of people's lives and property in the vast and deep areas from the shore to the land.
3. Knowledge about the ocean.
1. The reason for the blue color of the ocean.
Sunlight is composed of seven visible lights: red, orange, yellow, green, cyan, blue, and violet. These seven types of light have different wavelengths, and different depths of seawater absorb different wavelengths of light.
The red, orange, and yellow beams with longer wavelengths are gradually absorbed after entering the seawater, while the blue and cyan beams with shorter wavelengths are scattered and reflected in all directions when they encounter seawater molecules or other microscopic floating bodies suspended in the ocean.
2. Minerals in the ocean.
Dilute manganese nodules, petroleum, seafloor hydrothermal deposits, nickel, copper, cobalt, salt.
3. Marine animals.
Light Zone: (from the surface to 200 meters underwater) there are a large number of plankton, seaweed and coral reef organisms, including fish and marine mammals, as well as a large number of marine invertebrates, such as jellyfish, cephalopods, marine reptiles, seabirds, etc.
Low-light area: (200 to 1000 meters underwater) Most organisms have large morning eyes and light-emitting organs, and some animals hide in low-light areas during the day and go to shallow waters to find food at night.

10. In the boundless seawater, the cheerful waves dance briskly and gracefully, which is the joyful smile shown in the happy moment of the sea.
11. The sea water there is blue, and Wuzhizhou Island can be seen not far away, the scenery is very beautiful, but the waves are surging, and the waves are more than one meter high, so that people both love it and fear it, and even adults dare not approach it when they stand on the seashore, for fear of being swept into the sea.
12. The layers of waves expand and extend into the distance, slowly subsiding, as if taking a breath, leaving a fleeting foam and the musty smell of shaking seaweed.
13. Get close to the sea, comprehend the sea, and experience the voice of the sea, the sea naturally resonates with you, no need to deliberately force, no need to search hard, the sea, will always be with you with the sound of the tide, with its sea color with you comfort!
