In many villages and farms around us, small farmers and laborers have to carry heavy plastic tanks on their backs to spray chemicals on their crops. When they are spraying in the open fields, the wind often blows the dangerous chemical mist backward right into their faces and eyes.
This is a very serious problem because breathing in these chemicals causes immediate breathing trouble, severe coughing, and burning skin rashes. Over many years, doing this daily makes the farmers very sick with long-term lung diseases. It also causes heavy financial loss to poor farming families because they have to spend thousands of rupees on hospital treatments and miss work during harvest times.
I want to focus on this because the people who grow our food are risking their health every day just because they cannot afford expensive safety equipment. We need a low-cost, simple plastic shield or a better nozzle design for manual pumps so the chemical drift does not hit the farmer.
