The paper aims at studying and analyzing the language implementation of the development of peoples ecological consciousness in the present-day Russian and English-speaking media discourse environment. The modern media discourse has become an important source of various environmental lexical units which can affect peoples consciousness and change their behavior in a more eco-friendly way. The research is based on two parallel and opposite scientific approaches integrated in the media discourse which are ecologisation and anthropocentrism. The study is built on the analysis of the language models of ecological issues in different popular national and international media editions of Russia and English-speaking countries; in TV documentaries; on YouTube channels; in eco-friendly bloggers speeches and texts. The findings of the research showed that the media discourse environment is actively inculcating green ideas into peoples consciousness today both in Russia and abroad. More people are trying to follow the conscious consumption lifestyle. The media language is also becoming an important tool in introducing new environmental lexical units - neologisms - which are easily disseminated in the media discourse space and are actively being adopted by society. Overall, this research has confirmed the idea that the present-day language of the media discourse space is a powerful mediator of a new life sustainable development philosophy which helps human consciousness evolve in an eco-friendly way and try to make our planet a safer, healthier and more comfortable place for living.
