With people's extensive understanding of environmental crisis, ecological education has gradually stepped out of the ecological professional circle and entered the public stage. People are more and more aware that what is hidden behind ecological problems is the problem of people's value orientation. Ecological education not only enables people to acquire knowledge about the ecosystem, but also has the functions of breaking through the "knowledge standard", guiding and helping people to establish correct ecological values and shaping beautiful ecological feelings. Because only by loving nature can we consciously care for the environment and maintain the ecological balance, and can we "promote the harmony between man and nature, realize the harmony between economic development and population, resources and environment, adhere to the civilized development path of production development, affluent life and good ecology, and ensure sustainable development for generations." (Speech by Comrade Hu Jintao at the Central Forum on Population, Resources and Environment Work) Therefore, ecological education is the most effective and lasting means of ecological protection that "prevention is better than disaster relief".
