Final answer:
Sustainable farming and fishing help protect the hydrosphere by reducing water pollution, preserving aquatic ecosystems, and promoting responsible water use; therefore, the answer is d) All of the above.
Step-by-step explanation:
Sustainable farming and fishing practices can have a significant positive impact on the hydrosphere by addressing multiple concerns related to water usage and preservation. Reducing water pollution from agriculture is one of the most direct ways sustainable practices protect water bodies, preventing harmful pesticides, fertilizers, and animal waste from contaminating rivers, lakes, and oceans. Preserving aquatic ecosystems is another benefit, as sustainable fishing ensures that fish populations and habitats are not over-exploited, maintaining the natural balance and biodiversity. Furthermore, sustainable practices encourage responsible water use, maximizing efficiency and minimizing wastage, which is essential in a world where fresh water supplies are increasingly under pressure due to climate change and growing demands from domestic use and industry.
In conclusion, the answer to the question is d) All of the above because sustainable farming and fishing protect the hydrosphere by reducing water pollution, preserving aquatic ecosystems, and promoting responsible water use.
