The continuation of life depends on the presence of an adequate and good quality water supply. If all the water on Earth were condensed into a five-liter bottle, the amount of fresh water accessible to us humans would be just a tablespoon. In other words, the accessible amount of fresh water is less than 1% of the total water resources on Earth. The existence of a sufficient quantity of high-quality water is not only crucial for freshwater ecosystems but also for food security, sustainable development, and thus the future of humanity. Therefore, it is of great importance to protect freshwater resources. One of the major challenges we face in the 21st century is the limited availability of water resources. The sustainability of water resources is at the core of many issues such as food security, energy security, economic growth, climate change mitigation, and preventing the loss of biodiversity. Therefore, the limited availability or excessive use of water resources now concerns all of us. In the project focused on our seas, which constitute the most important part of our water resources, the aim is to raise awareness about the essential source of human life. Seas are of vital importance not only for the biological diversity and ecosystem services of our planet but also for the water cycle and the climate system. Seas host an incredibly rich wildlife, ranging from microscopic plankton to the largest mammal, the blue whale. Seas contribute to sustainable development, economies based on the "sustainable ocean," the eradication of poverty, food security, nutrition, livelihoods, maritime trade, and transportation. Our seas are currently facing a serious threat. Our way of using the seas and coastal areas not only threatens biodiversity but also the ability of these natural resources to meet the basic needs of millions of people. Overfishing, pollution, and climate change have a negative impact on this process. Centuries of excessive use and neglect have led to crises that remind us that it is time to change our perspective on these vast blue areas that cover almost three-quarters of the Earth's surface. Only 4% of the oceans and seas are under protection. In the last 50 years, 34% of the fish population in the Mediterranean has been lost. One-third of global tourism activities take place in the Mediterranean. We are working with our partner organizations to raise awareness and create healthy seas that support rich biological diversity, sustainable livelihoods, and a growing economy. In line with the project objectives, it is planned that first the partner organizations and then the participants from six different countries bordering the sea will be informed about the measures that can be taken to protect marine ecosystems and the policies that can be implemented. At the same time, they will be able to conduct qualified data analysis regarding endangered or extinct marine species. Each participant will return to their country after the project to integrate with people from 3 different cultures, benefiting from Erasmus priorities. Participants who develop sensitivity to the value of water in human life will be encouraged to volunteer in activities to protect the seas. In general, we are working on measurable new studies to support the protection of at least 30% of coastal and marine ecosystems worldwide, as well as increasing effective management and sustainable fishing practices.
