Answer:
Environmental impact
Step-by-step explanation:
Ethanol is a type of biofuel that is made from plant materials, such as sugar cane or corn. In Brazil, ethanol is commonly used as a fuel for cars, especially flex-fuel vehicles that can run on either gasoline or ethanol. Ethanol is often cheaper than gasoline in Brazil and is seen as a more environmentally friendly alternative to fossil fuels.
However, there have been some concerns about the use of ethanol in Brazil. One issue is the potential impact on food prices, as the production of ethanol from crops like sugar cane can compete with food production. Additionally, there have been concerns about the environmental impact of ethanol production, such as deforestation and greenhouse gas emissions.
