In 1964, Rachel Carson testified before Congress about the negative impacts of this chemical. She said “If we are ever to solve the basic problem of environmental contamination, we must begin to count the many hidden costs of what we are doing.” What do you think she meant by “hidden costs”?

By "hidden costs," Rachel Carson likely meant the indirect and long-term consequences of using the chemical she was discussing. While the immediate benefits may have been evident, Carson wanted to draw attention to the potential environmental and human health risks associated with its usage. These hidden costs could include ecological damage, loss of biodiversity, contamination of water sources, harmful effects on wildlife, and even potential impacts on human health. Carson was advocating for a more holistic approach to decision-making, where the costs and consequences of actions are thoroughly evaluated before making environmental choices.
