Eco-nationalism (or ecological nationalism) manifests as a desire to eliminate reliance on foreign sources of fuel and energy by promoting alternate energy sources that can be adequately created and maintained with a nation's boundary. Brazil displayed an example of this by becoming completely energy self-reliant.
According to J. Dawson, eco-nationalism is the rise of social movements that closely connect problems of environment protection with nationalist concerns. In former Soviet Union citizens perceived environmental degradation as both a systemic fault of socialism and a direct result of Moscow's desire to weaken a particular nation by destroying its natural base, and exploiting its resources. Estonian, Lithuanian and Ukrainian independence movements drew great strength from environmental activism, especially from an antinuclear stance. In 1985-1991, eco-nationalism was one of symptoms and at the same time a new impulse for disintegration of the Soviet Union.
