Answer:
yes ocean are useful to the mankind
it is useful by these ways:
•it is a medium of transport which helps us to go from one place to another
•it provides us sea food
•it is a source of minerals
•it is a source of fossil fuel like petroleum
•the tides of ocean is used to generate electricity
Answer:
1. The Ocean produces more oxygen than the Amazones.
It is often thought that rainforests are the primary source of oxygen on the planet, but the truth is that rainforests are only responsible for 28% of the oxygen on earth while oceans are responsible for the 70%. It does not matter how far we live from the sea, from every ten breaths you take seven come from the ocean. Have you ever seen a tree in the middle of the sea? No, right? That is because the Ocean does not need them, the phytoplankton has got it covered. Phytoplankton is a microscopic plant, a component of the plankton, which spends its life being carried by oceanic currents. Basically, these tiny little organisms act in the same way as tree leaves do on land. Phytoplankton absorbs carbon dioxide and releases oxygen. We do not see them, so we tend to forget about them if we even know about them in the first place. They are one of the tiniest beings on the planet, but one of the most important to have around, keeping us alive.
2. The Ocean regulates the Earth climate.
In many ways, the sea regulates our climate. It soaks up the heat and transports warm water from the equator to the poles, and cold water from the poles to the tropics. Without these currents, the weather would be extreme in some regions, and fewer places would be habitable. It regulates rain and droughts. Holding 97% of the water of our planet, almost all rain that drops on land comes from the sea. The ocean absorbs CO2, to keep the carbon cycle, and accordingly temperatures on earth, in balance. It is like our global climate control system.
3. It is an important source of food.
The ocean is the number one source of protein for more than a billion people. Fish accounts for about 15.7% of the animal protein consumed globally (2). Although, not everything is fish and seafood. Humans have traditionally used algae and sea plants for cooking sushi, seaweed pancit in Philippines, sea grapes, dulse, etc. There is a growing tendency of using algae and sea plants on our daily and start-ups like, “This is seaweed… ” (3) are making sure to introduce it in our supermarkets. Considering the world population growing by 1.5 million people every week, we are relying on the ocean more and more for survival, and we need from an alternative and nutritious food sources. For those who are not into eating insects, edible seaweed might be a good alternative.
4. Many creatures depend and live in the Ocean.
The ocean is not just home to us ocean lovers, but it is home to the greatest abundance of life on our planet. When you sail across an ocean, you will see dolphins, whales or a turtle popping up to take a breath. That is just what we see on the surface; there is more life below the ocean’s surface than on land. Experts predict4 that there are more than 300.000 different species underwater, and is still not clear how many of them we know. All the creatures that live in the Ocean play an essential role in the trophic chain of the ecosystems. Due to climate change (5), the ocean has been warming and losing oxygen, and its pH has been decreasing. Many marine species have already been adjusting their geographic and depth ranges with changes in sea temperature. However, not all species may be able to move to avoid thermal stress, and global warming has already been correlated with mass mortalities in the Mediterranean. With more than 60% of the world’s population living on the coastline, we all depend on a healthy sea just as much as these beautiful creatures. “The sea, the great unifier, is man’s only hope. Now, as never before, the old phrase has a literal meaning: we are all in the same boat.”- Jacques Yves Cousteau
5. The best holidays are close to the water.
The ocean is a happy-zone! Our temple, our life, our second home, our exhilaration place. It’s where we swim, surf, sail, dive, chillax, and ‘lime’. Family holidays and Sundays often happen on the beach. For sailors, fisherman and islanders, it also is a transport zone. It carries us to new lands, and connect us with nature and each other. As sailors, we also serve as educators, ambassadors and advocates of a lifestyle on the water. Together we share a passion for the ocean, and an avid desire to keep our playground clean and safe forever. Waterways are crucial to our health, for us and future generations.
