was a controversy by other researchers saying that the future generation's ability to enjoy an acceptable standard of living would be on shambles if due attention were not immediately paid to social and environmental aspects as well as economic. This they said requires shift in the worldview from treating the environment as part of the economy to treating the economy as part of the environment; strategically this means the economy should be adapted to ensure environmental services are maintained. Some contributors recommended developed capitalist societies to act quickly to become more sustainable. Other researchers underscored the imperative for developing countries not to follow the western models of unsustainable development.

Three basic constraints to financing sustainable development (SD) are:

Competing priorities for limited resources, particularly in LDCs
Undelivered pledges made at the international conferences to finance SD.
Externalities, such as increased oil prices, conflict, and natural disasters that alter the development priorities of many countries.
Initiatives to overcome economic and financial barriers
In other to achieve economic growth without threatening social development and environmental resources, new and different 'vehicles' for growth must be oriented to different country situations.

Governments should be responsible for market-led problems with incentive for the private sector to become problem-solvers, and not polluters.

There is need to shift the incentive and motivating structure for farmers around the world. Policies makers should promote agricultural production that is based on significantly higher labor inputs per area and significantly more diverse production streams.

There is need to reform the calculation of economic growth and removal of weapons-related cost from GDP would provide a strong indication of relative spending toward sustainable development to politicians.

Justifying the need to abandon linear system of industrial production based on total exploitation of natural resources, over production, and waste generation in favor of a circular system of production using clean technologies and the elimination of waste resources.

Social barriers
Population growth, paired with unsustainable consumption and production patterns among the wealthy, are the biggest social challenges to achieving sustainable development in the world and developing countries. Absent of a significant change in human behavior, sustainability will not be potential. There are other social barriers which are:

The marginalization of the poor and entrenched inequities
Limited awareness about sustainable development
Environmental issues among both politicians and the wider public fragmented civil society
Inadequate interaction between civil society and government
Insufficient incentives to for the private sector to pursue sustainable development
Initiatives to overcome the social barriers
Need for stronger policies to address income disparity and population growth.
The introduction of programmes to create awareness and build capacity in the field of sustainable development among the general public can assist to the change in behavior and lifestyle that is needed to achieve sustainability.
