Biogeochemical cycles are processes that involve the transfer and recycling of essential chemical elements for life between the biotic and abiotic components of an ecosystem. The carbon cycle is one of the most studied, and human activities have significantly affected this cycle, especially through the burning of fossil fuels. In a college entrance exam environment, students are challenged to apply their theoretical knowledge of biogeochemical cycles to understand and explain changes that human action can cause in these cycles. Based on this context, write a text discussing the carbon cycle and the main ways human activity affects it. Then, propose and justify an action that could be implemented to minimize the negative impact of human activity on this cycle, considering the scientific, technological, and social aspects involved.

The sulfur cycle is an important biogeochemical cycle that involves the movement of sulfur between living organisms and the environment. This chemical element is essential for life, being found in the form of organic acids and amino acids, among other molecules. Sulfur has various biological functions, such as the formation of connective tissues, the transport of oxygen in the blood, and the production of energy. What are the main stages of the sulfur cycle?
