Drones have increasingly become integral tools across various domains due to their versatility and technological advancements. For agricultural practices, drones can efficiently spray pesticides over vast crop fields, ensuring uniform coverage and reduced human exposure to chemicals (Activity 1). In geological surveys, drones equipped with high-resolution cameras and sensors can safely inspect the hazardous and difficult terrains of active volcanoes, providing critical data without risking human lives (Activity 2). Lastly, drones can be utilized in marine biology to collect breath samples from whales, allowing researchers to analyze DNA while minimizing disturbance to the animals (Activity 3). Thus, the capability of drones to operate in diverse environments makes all three activities feasible and underscores their growing relevance in modern scientific and environmental research.
