World Oceans Day History
1: Who was the first woman President of India?
World ocean day is observed every year on June 8. The world oceans day was officially announced by the united nation in the year 2008. The idea of observing ocean day was proposed by the Canada’s International Centre for Ocean Development (ICOD) and the Ocean Institute of Canada (OIC) at the Earth Summit in the year 1992. This international day also supports the Sustainable development goals and aims to create awareness among the society on the importance of protecting the ocean
During 1987 to 1992 the Brundtland commission which is also known as world commission on environment and development noted in their reported that the ocean sector lacked strong voice when compared to the other sectors. In 2004 In 2004, The Ocean Project and World Ocean Network launched the petition “Help Make a Difference for our Ocean Planet!” to recognize June 8 as the world oceans day.

Reasons Why the Ocean is Important
1. Ocean produces more than 50% of the oxygen on earth
Phytoplankton plays a major role being a part of ocean and fresh water system. The Phytoplankton in the oceans are the reason for the production of more than 50% of the oxygen. They undergo photosynthesis like plants and trees on land. They are found near the well lit surface layers of the oceans and lakes. Like plants they contain chlorophyll through which they absorb sunlight and through photosynthesis they convert it to energy and release oxygen to the atmosphere thus being the major contributor of oxygen to the land.
2. The ocean helps in regulating the climate of the earth
Ocean covers approximately seventy percentage of the earth’s surface. The Ocean transports heat from the equator to the poles thus regulating the climate at equator regions. It also transports cold water from the poles to the tropics thus regulating the climate conditions in both the places. If this regulation of weather and climate does not happen then the weather conditions would have been extreme in one region and few areas will not be suitable for habitat as well. The ocean also plays a role with respect to rain and droughts.
3. Ocean accounts for being the major source of food
Ocean serves as main source of nutrients to billions of people around the world. The wide variety of fishes serves as a important nutrient for consumption to the point that it serves approximately sixteen percentage of the animal protein consumed worldwide.
4. Ocean provides home to an abundance of life
Ocean is a home for large species of life. From smallest microorganism to the largest whale , it provides home for different species of living organism. Ocean contributes to about 90% of habitable space on the earth including variation in plants, animals, fungi and microorganisms. Till now the exact number of species in the ocean is not known. The world’s oceans has around 500,000 to 10 million marine species.
5. Ocean provides economic benefits
In most of the developing countries millions of people rely on ocean for their jobs and livelihood. Specially in the coastal areas , tourism and fisheries contribute to most of the income of the people in those areas. Currently the marine technologies, renewable energy, aquaculture, biotechnology, offshore oil and gas has increased the economy by greater extent thus providing jobs to many. Ocean based industries also play a major role in this.
Threats to the Ocean – Causes of Ocean Pollution
- Ocean Acidification: Human activities as caused an increase in CO2 in the atmosphere. Ocean absorbs 30% of the the CO2 from the atmosphere. As the CO2 absorbed by the seawater increases due to chemical reactions the concentration of hydrogen ion increases. Ocean acidification causes harmful effects on the ocean species.
- Global warming: The ocean absorbs heat from the green house gas emissions which is causing the rise in the ocean temperatures. The increasing temperature of the ocean is affecting the marine Eco system.
- Excessive usage of plastic: Plastic that end up in oceans are mistaken by the marine wildlife for food and they finally reach their stomach. Thousands of marine animals like sea birds, turtles and whales aare killed each year due to plastic pollution.
- Poor waste management: Sewage and harmful chemical waste from factories when left to ocean causes ocean pollution with the toxic chemicals. Inappropriate waste management from factories cause serious concern to ocean and its marine life.
- Over-fishing: Over-fishing and poor fishing management has endangered our marine species. Over fishing is the worst impact humans have done to the oceans. It is estimated that more than 70% of the world’s fish species have been exploited. Fishing the species more faster than they can reproduce is causing this. It is estimated that 31.4 percent of fish stocks are either fished to capacity or over fished.
