Critical rationalismCritical rationalism is an epistemological philosophy advanced by Karl Popper on the basis that, if a statement cannot be logically deduced (from what is known), it might nevertheless be possible to logically falsify it. Following Hume, Popper rejected any inductive logic that is ampliative, i.e., any logic that can provide more knowledge than deductive logic. In other words if we cannot assert it logically, we should at the least try to logically falsify it, which led Popper to his falsifiability criterion.
Political ecologyPolitical ecology is the study of the relationships between political, economic and social factors with environmental issues and changes. Political ecology differs from apolitical ecological studies by politicizing environmental issues and phenomena. The academic discipline offers wide-ranging studies integrating ecological social sciences with political economy in topics such as degradation and marginalization, environmental conflict, conservation and control, and environmental identities and social movements.
Eco-socialismEco-socialism (also known as green socialism, socialist ecology, ecological materialism, or revolutionary ecology) is an ideology merging aspects of socialism with that of green politics, ecology and alter-globalization or anti-globalization. Eco-socialists generally believe that the expansion of the capitalist system is the cause of social exclusion, poverty, war and environmental degradation through globalization and imperialism, under the supervision of repressive states and transnational structures.
EcotourismEcotourism is a form of tourism marketed as "responsible" travel (using what proponents say is sustainable transport) to natural areas, conserving the environment, and improving the well-being of the local people. The stated purpose may be to educate the traveler, to provide funds for ecological conservation, to directly benefit the economic development and political empowerment of local communities, or to foster respect for different cultures and human rights.
