Modern farming techniques have significantly boosted crop yields in recent times. Advancements in biotechnology, use of fertilizers, pesticides, and machinery have led to more efficient farming and larger harvests. Methods like precision farming and hydroponics have also contributed towards increasing crop yield while minimizing the use of resources. However, these techniques also come with their own set of challenges such as soil degradation and environmental pollution. Overall, while modern farming has been a boon for crop production, it's also important to consider and address its environmental impact.
