Every year on June 8, people around the globe come together to celebrate World Oceans Day, a day dedicated to honouring the vital role that oceans play in our lives and advocating for their preservation. The oceans are not only a source of inspiration and beauty but also crucial to the health of our planet. They regulate climate, produce oxygen, and provide food and livelihoods for billions of people.
The Theme: Planet Ocean: Tides are changing
The theme Planet Ocean: Tides are Changing emphasises the urgent need for transformative action to restore and protect the health of our oceans. This theme reflects the growing recognition of the critical state of marine ecosystems and the collective responsibility we share in reversing the damage done by pollution, overfishing, and climate change.
According to Mrs Dileshwari Hirwani, PRT Science at Apeejay School, Nerul, there is an urgent need for collective action to address the challenges facing our oceans. “The theme highlights innovative solutions to preserve marine biodiversity and promote the sustainable use of ocean resources. It is crucial for everyone, especially students, to recognise the importance of our oceans and to get involved in protecting them. By adopting sustainable practices and supporting new technologies, we can all contribute to safeguarding these vital ecosystems for future generations. Let’s work together to ensure a healthy and thriving ocean for years to come,” the educator advised.
The significance
Oceans cover more than 70% of the Earth’s surface and are home to an estimated 80% of all life on the planet. They play a pivotal role in regulating the Earth’s climate by absorbing carbon dioxide and heat, which helps to stabilize global temperatures. Oceans are also a major source of oxygen, produced by marine plants and phytoplankton.
Moreover, oceans support a diverse range of species, from the smallest microorganisms to the largest whales. They provide food and resources for billions of people worldwide and are integral to many cultures and economies. The health of our oceans is directly linked to the health of our planet and ourselves.
Despite their importance, oceans face numerous threats:
Pollution: Plastic pollution is one of the most visible and pervasive problems, with millions of tons of plastic waste entering the oceans each year. This pollution harms marine life and ecosystems and poses significant risks to human health.
Climate Change: Rising temperatures and ocean acidification, caused by increased carbon dioxide levels, are having detrimental effects on marine ecosystems. Coral reefs, which are particularly sensitive to temperature changes, are experiencing widespread bleaching and die-offs.
Habitat Destruction: Coastal development, pollution, and destructive fishing practices are damaging critical habitats such as coral reefs, mangroves, and seagrass beds.
Take Action
Reduce Plastic Use: Cutting down on single-use plastics and properly disposing of waste can significantly reduce plastic pollution in oceans.
Participate in Clean-up Efforts: Joining local beach clean-ups or organising community events can help to remove litter from coastal areas and raise awareness about the impact of pollution.
Advocate for Policy Change: Supporting policies and legislation that protect marine environments and reduce carbon emissions is crucial for long-term ocean health.
Educate and Raise Awareness: Educating others about the importance of oceans and the threats they face can inspire collective action and foster a sense of stewardship.
