History of National Marine Week
National Marine Week was organized to motivate people to better understand and care for the ocean. The holiday encourages us to appreciate and protect our oceans. During National Marine Week, people take time to focus on how vital the oceans are to humanity, given that they constitute the largest ecosystem on the planet. In addition to containing 97% of the planet’s water, they also make up 80% of the planet’s biodiversity, with more than 30,000 species.
However, the natural world is rapidly degrading. The oceans are under threat as a result of global warming. The primary factors can be attributed to human activities, so we must do everything we can to assist in saving them. The bottom line is that if we end up losing the oceans, everything will quickly deteriorate. It has been estimated that about 80% of global marine fish populations have been overexploited or depleted, according to the Food and Agriculture Organization of the United Nations (FAO). Due to the threat posed by this, biodiversity is imperiled, with severe consequences to food security and the global economy.
According to a published study, the world’s frozen oceans are melting at a rate that is significantly quicker than previously predicted. The world’s glaciers are now the smallest they’ve ever been in mankind’s history, and their melting is responsible for one-third of the rising of the world’s sea level. A few examples of materials discarded in the ocean that are particularly detrimental to marine life include cigarette butts, fishing wires, and large amounts of plastic debris, all of which are biodegradable.

How many marine species exist?
Scientists estimate there are between 700,000 and one million known marine species, with many more yet to be discovered. This incredible biodiversity highlights the vastness and complexity of ocean ecosystems.
What is the biggest threat to marine life?
The biggest threat to marine life is often considered to be climate change, leading to ocean warming, acidification, and sea-level rise, which disrupt ecosystems and endanger species. Overfishing and plastic pollution are also major contributors.
National Marine Week Activities
Avoid disposable plastics
Commemorating National Marine Week by choosing reusable containers, such as coffee cups and water bottles, is an excellent place to start. If you'd rather not pollute the environment, go for reusable bags instead of plastic ones as they perform the same functions while posing no environmental harm.
Go out with family
To celebrate, get the whole family out in nature and teach the younger children about the world around them. One easy way to get engaged is to go out to the sea and observe marine life. While you are there, pick up any litter you see.
Support local conservation efforts
Support the holiday by attending any one of its numerous events. You may also donate to a charity dedicated to preserving the animals and plants in the ocean. Volunteering is also a good way to show your support.
5 Important Facts About The Ocean And Marine Life
Oxygen supply

Largely unexplored
It is estimated that humans have explored only 5% of the world's waters thus far.
The Pacific Ocean
The largest ocean was named after the Latin phrase ‘Tepre Pacificum,’ which translates to “Peaceful Sea.”
The deepest part of the ocean
The deepest known part of the Earth's ocean is a mind-blowing 6.8 miles below the water surface.
Only a few species discovered

Why We Love National Marine Week
It encourages preservation
Raising awareness about the marine and coastal ecosystem, and encouraging the responsible use and preservation of natural resources, is the mission of the day. This benefits all generations, present and future.
It pushes for a healthy ocean
For environmental reasons, marine life conservation is critical. The oceans contain 80% of Earth's biodiversity, are the world's largest ecosystem, and are a major source of food. Healthy oceans help maintain our environment and atmosphere by absorbing carbon dioxide and exhaling oxygen, just like land plants.
It educates people
The two weeks are filled with events and initiatives that educate people about the crucial marine life concerns. Marine life is threatened by a variety of factors, some of the most serious of which include overfishing, plastic pollution, and other pollutants that end up in coastal waters. These things harm marine life, vegetation, and animals.
