Sustainable development means "meeting the needs of the present without compromising the ability of future generations to meet their own needs" (United Nations Brundtland Commission). One of the most important needs is undoubtedly a livable environment for all living species. Our "Zero Waste Philosophy With The 3R Rule" project was structured on this basis, and young people from five countries worked together on this issue. Waste is any substance generated as a result of production and consumption activities that, if released into the environment, harms humans and wildlife. As the world's population grows, more waste is produced every day. Waste poses numerous harms to nature, living creatures, and the economy. All people on Earth have a shared responsibility to the environment. By controlling daily consumption habits and raising people's awareness of waste management, we can contribute to the most efficient use of resources for both the environment and the economy. As young people are our future, we have helped them become conscious of this issue by informing them. The IPCC (Intergovernmental Panel on Climate Change) report released in August 2021 was alarming. As experts say, we still have time to limit the damage caused by human-induced climate change, but we must act now. Therefore, we believe it is vital to educate and raise awareness among younger generations about this crucial issue, not only at the local level but also to share our observations with European partners. Environmental issues and sustainable development are global challenges, and with this project, we wanted to show people that by working together, we can create significant change. The project also enabled our participants to communicate in English, thus helping them improve their language skills. With this project, we aimed to raise awareness among young people about waste generated in their surroundings, schools, workplaces, and homes, to question how waste management can be implemented, and to develop environmentally friendly strategies with their project colleagues. Our project aimed to teach young people the principles of reducing waste, encouraging them to reuse if it cannot be reduced, and ultimately focusing on recycling. The project's objectives were as follows: - To instill in young people the principle that "Not all waste is garbage" - To raise and develop awareness among our target audience about protecting the environment, keeping it clean, and making recycling a way of life - To emphasize the environmental and economic benefits of waste management - To ensure that young people learn the importance of contributing to all ongoing "Zero Waste" projects - To ensure that young people learn about the contribution of recycling to the national economy by developing "Environmentally Friendly Strategies" and observing their implementation in the environment - To increase participation in responsibility projects - To develop young people's skills and attitudes - To raise awareness about social issues and thus encourage active community participation in projects - To introduce young people to nature conservation organizations that aim to prevent and compensate for damage to nature - To equip young people with skills such as communication skills, collaboration, leisure time management, and proper use of digital platforms - To promote intercultural dialogue, learning, and a sense of European identity. - To raise awareness of climate change, global warming, and the protection of nature and human life on a local and global scale. - To develop participants' multiple intelligences, technological skills, and the use of web tools. - To strengthen European values and break down prejudices and stereotypes. - To encourage young people to engage in mutual and collaborative learning. - To connect with the soil and escape the stresses of daily life
