The ecological environment is the main challenge for the accession of European countries to join the European Union. Ecology is at the heart of the policy-making process of European countries, respecting the interests of companies and consumers. Due to the low level of environmental awareness of European countries, which are not members of the European Union, enlargement with new members can slow down or even set the European Union back when it comes to ecology. The reasons are: underdeveloped environmental policy, low gross domestic product. The European Union invests its funds for the environment, but countries are obliged to allocate most of the funds from their gross domestic product. Therefore, special taxes are introduced on the consumption of certain products for the protection and preservation of nature. Taking significant environmental measures will have an impact on protection against ozone depletion and global warming. A healthy environment creates the conditions for a healthy life. Therefore, an appropriate ecological awareness is necessary, which is a pattern of life, harmonizing behavior with the natural laws of the circulation of matter, energy expended and the renewal of life, which encourages taking from nature as much as necessary. Ecological ethics is the ecological relationship of man to the environment, which establishes a moral relationship between the human / technosphere and the natural / biosphere. A new attitude towards the environment as well as a transformation of the spirit of the modern sphere of work is becoming an imperative, a concept of sustainable development with the harmony of different economic and social relations.
