Summary 

Modern societies are facing many challenges one of which is a problem of the resources global deficiency. The global deficit is one of the main problems of modern society.

The problem of the global deficit is the basis of the current economic models in which the permanent aspiration of human beings to satisfy the growing needs faced with the scarcity of the resources. The human consumption of goods and services is associated with a significant number of waste and environmental pollution, which in turn requires additional resources for environmental cleanliness and waste removal.

The paper considers new conceptual approaches – “Green” Economics and “Blue” Economics – as a way to decide the problem of resources global deficiency and environment pollution.

Green Economics is a relatively new direction of economic science and practice that recognizes the dependency of economic activity on nature and considers the economy as a component of nature.

Green Economics is one of the tools to achieve sustainable development. Green Economy is considered as economic activities that are directed on the achievement of the human wellbeing and social justice without environmental damage.

The concept of the Green Economics is based on three major assumptions:

-         It is impossible to expand infinite influence in the limited space;

-         It is impossible to satisfy the growing demands in conditions of resources scarcity;

-         Everything on Earth is interdependent.

But there is some contrariety in the concept of Green Economics because the concept is related to the necessity to make a large scale of investments for the protection of an environment. Therefore, the Green Economics provides an important role in the implementation of recycling or non-waste technology, but cannot solve the problem of saving resources.

The problem of harmonization of the resources utilization with economic activity could be solved through the so-called “Blue Economics” concept.

Blue Economics is a new challenge of modernity which aims to solve today existing problems like unemployment, poverty, lack of resources, a necessity to raise human welfare, ecological safety, etc.

Blue Economics is an innovative approach to business management, which provides a harmonious connection between nature and business activity.

Blue Economics is based on three main principles:

-      Every resource can be substituted by another resource;

-      Nature does not create residuals, and neither businesses nor humans should create waste;

-      Any residue created by production and consumption is the source of production of another product.

The Blue Economics is derived from the study of the natural ecosystems’ dynamics which are considered as necessary and useful prerequisites for the successful modeling of production and consumption.

According to the concept of the Blue Economics, economic systems and business models act as ecosystems, and nature is considered as the best source of useful ideas for solving socio-economic problems in society.

Thus, the concepts of  Green Economics and Blue Economics are not just scientific paradigms, but above all, they are an innovative conceptual vision, a new rule of new thinking, a new lifestyle and "man-nature" new coexistence. The concepts of Green and Blue Economics cardinally change the vision of production and habits of consumption, as well as methods of business activity, establish a friendly business environment for eco-systems and innovative business models.

In such a way the concepts of Green and Blue Economics provide sustainable economic development in terms of maintaining intellectual consumption and resources preservation.
