Organic farming focuses on sustainable agriculture, avoiding synthetic chemicals and GMOs, and emphasizing crop rotation, composting, and biological pest control to maintain soil health and biodiversity. It often results in higher biodiversity and healthier soil but can have lower yields and higher labor costs compared to conventional farming.

Hydroponics is a soil-less farming method where plants grow in nutrient-rich water. It allows for precise control of nutrients, reduces water usage by up to 90%, and can produce higher yields in a smaller space. However, it requires significant upfront investment and energy for lighting and temperature control, making it less sustainable in terms of energy consumption.

Aquaculture, the farming of fish and other aquatic organisms, provides a substantial source of protein and can relieve pressure on wild fish populations. It can be practiced in various environments, including freshwater and marine systems. However, poorly managed aquaculture can lead to environmental issues such as water pollution, disease spread, and habitat destruction.

Each method has its benefits and drawbacks, with organic farming emphasizing environmental sustainability, hydroponics maximizing efficiency and yield, and aquaculture offering a sustainable protein source if managed responsibly. The choice depends on specific goals, environmental conditions, and resource availability.
