Final answer:
Stricter regulations on alcohol advertising can help reduce the alcohol-related death toll by limiting exposure, especially among youths, rather than increasing availability or encouraging excessive consumption.
Step-by-step explanation:
Environmental changes that can help reduce the alcohol-related death toll include options such as implementing stricter regulations on alcohol advertising. By reducing the exposure and appeal of alcohol, especially among the youth, it's possible to decrease its consumption and related harms. On the other hand, increasing the availability of alcohol in public spaces, encouraging excessive alcohol consumption at social events, and reducing the legal drinking age would likely create more accessibility and therefore increase the risks and negative consequences of alcohol use. It is clear from historical evidence and public health research that creating environments which do not glamorize or facilitate easy access to alcohol tend to be more effective in promoting responsible drinking behaviors and reducing alcohol-related problems such as domestic violence, accidents, and underage drinking.
