Ecopsychology is a new way of thinking about our relationship to nature. It is the idea that people need to be connected to nature to be healthy and happy. In other words, it doesn't just mean learning to take better care of the planet, but also taking care of ourselves by connecting with nature and learning to have a healthy relationship with it. So, it's about spending time in nature, noticing the things around us and appreciating their beauty, and making an effort to help keep nature healthy.
