Final answer:
Poor ventilation of indoor smoke from cooking with biofuels is associated with respiratory issues.
Step-by-step explanation:
Poor ventilation of indoor smoke from cooking with biofuels is associated with respiratory issues. When biofuels are burned indoors without proper ventilation, it can release harmful pollutants into the air, which can be inhaled and cause respiratory problems.
The smoke and pollutants from burning biomass can be problematic and lead to respiratory infections, especially among women and children in developing countries who are exposed to them for long periods of time.
