Marine conservation is also known as ocean conservation,is the protection and preservation of ecosystems in oceans and seas. Saving wild ocean places, for us and future generations. The Ocean is the heart of the planet. Water covers more than two-thirds of the Earth’s surface. Sea plants, like Posidonia , produce 70% of the oxygen we breathe (1), and the deep waters are home to wildlife and some of the biggest creatures on earth. It provides us with food, jobs, life, entertainment, and sailing!
Marine conservation as a concept is relatively new. It was only in the 1960s that it was generally acknowledged that major fish populations were in decline and ecosystems were dramatically deteriorating. Today, marine conservation is considered one of the greatest scientific problems on our planet. Ecosystems have changed irreversibly, ocean management is fragmented and oceans are managed independently of the terrestrial (land) environment.
Oceans are an important source of food. They host 80 percent of the planet’s biodiversity, and are the largest ecosystem on Earth. Fish provide 20 percent of animal protein to about 3 billion people.Oceans regulate our climate.Oceans are an essential component of the Earth’s ecosystem.Unfortunately, different human activities are putting our oceans under threat. Overfishing is reducing fish populations, threatening the supply of nutritious food and changing marine food webs. Approximately 80 percent of the pollution in the oceans comes from land, and coastal zones are especially vulnerable to pollutants. Plastics are also particularly problematic with enormous floating rubbish patches forming in the oceans. Climate change and its related impacts, such as ocean acidification, are affecting the survival of some marine species. Coastal development is destroying and degrading important coastal marine ecosystems such as coral reef, seagrass meadows and mangroves.
We need clean and healthy oceans to support our own health and survival, even if we don’t live anywhere near them. Each and every one of us can make a difference, it’s time to take action! Think about which threats to the oceans concern you the most or think about which ocean plants, animal species, habitats or ecosystems you want to conserve, protect and restore locally and globally
The problem with invisibility, is that it is very difficult to understand a full chain of events- so how an invisible problem can lead to serious issues. For example, an increased input of nutrients in the water (by fertilizers and raw sewage) can lead to an Algae bloom on the surface, which smells a bit funny, but isn’t a problem in itself. The issue here is that the Algae casts a shadow over the water, which has direct implications for other organisms below the surface of the water- for example they can’t photosynthesise , and even worse, when the bloom dies off, the decomposition uses up all the oxygen in the water, suffocating everything in the area.If you imagine this happening on a grand scale, across the oceans, rivers and lakes of our world, you can understand why marine ecosystems are in jeopardy. Our marine conservation project in Thailand works hard to understand the deterioration of the local ecosystems and to try to rebuild them where possible. This has been a great success so far, and it is an ongoing mission. Research data is currently being shared with the Thai government with the end goal of tightening up legislation to protect a greater marine area.
