Who Is Henry David Thoreau?

Thoreau’s works are important sources of literature in contemporary environmentalism. The author's writings were critical of the relationship between man and the planet. According to the Center for American Progress, Thoreau condemned irresponsible and unrestrained utilization of natural resources (1). Thoreau remarked that men if men could fly, they would waste the sky in the same way they have messed the earth. Obviously, he took delight in the fact that man’s inability to fly has saved the sky from unsustainable exploitation. In this regard, environmental responsiveness was the hallmark of Thoreau’s work. He believed in the treatment of the environment with respect. Thus, Thoreau made a significant contribution through his philosophy of social responsibility and sustainable development when the environment was in danger of adverse exploitation due to the emergence of industries.

Such initiatives were important in protecting the environment and improving public awareness of the conversation.
