Please answer a question about the following article about Estonia:

Today, Estonian society encourages liberty and liberalism, with popular commitment to the ideals of the limited government, discouraging centralised power and corruption. The Protestant work ethic remains a significant cultural staple, and free education is a highly prized institution. Like the mainstream culture in the other Nordic countries, Estonian culture can be seen to build upon the ascetic environmental realities and traditional livelihoods, a heritage of comparatively widespread egalitarianism out of practical reasons (see: Everyman's right and universal suffrage), and the ideals of closeness to nature and self-sufficiency (see: summer cottage).

What ideal does Estonia hold towards the environment?
closeness to nature
