Meaning: This quote by David Brower, a renowned environmentalist, reflects his concerns about the lack of understanding and control that ordinary people have over complex machinery and technologies, particularly those with potential environmental impacts. Brower's words convey a sense of caution and skepticism about the ability of individuals to responsibly handle complex systems without adequate knowledge and oversight.

Brower's concern about people not knowing much about what they are doing suggests a lack of awareness and understanding among the general population when it comes to dealing with intricate and advanced technologies. This lack of knowledge can pose significant risks, especially in the context of environmental impact, where the consequences of mishandling or misusing machinery can be far-reaching and detrimental. The quote implies that the complexity of modern machinery and technology may surpass the average person's capability to fully comprehend and control its effects.

Furthermore, Brower highlights the issue of insufficient control, pointing to the fact that there may not be enough oversight or regulation in place to ensure that these complex systems are managed responsibly. This lack of control can potentially lead to negative outcomes, particularly in the environmental realm, where unchecked technological activities can have severe ecological repercussions.

When Brower mentions the insufficient capability of ordinary people to tinker with such complicated machinery, he is underscoring the idea that the average individual may not possess the necessary expertise or skills to manipulate or manage complex technology effectively. This sentiment reflects a broader concern about the potential hazards of allowing unqualified individuals to interact with advanced machinery that could have significant environmental implications.

David Brower's background as an environmentalist and his extensive work in conservation and advocacy for the protection of natural resources lends weight to his perspective on this issue. As the founder of numerous environmental organizations and a key figure in the modern environmental movement, Brower's concerns about the potential risks associated with the inadequate understanding and control of complex machinery carry considerable authority.

In conclusion, David Brower's quote serves as a cautionary reminder about the challenges and potential dangers associated with the interaction between ordinary people and complex machinery, particularly in the context of environmental impact. His words prompt us to consider the need for enhanced awareness, oversight, and capability when dealing with advanced technologies, especially those with the potential to affect the environment. By acknowledging the limitations of individual understanding and control, Brower's quote encourages a thoughtful approach to the responsible management of complex systems for the benefit of both society and the natural world.
