The answer is diet, or lifestyle but I recommend diet more
I would say A because it sounds the most positive and sometimes people need a little push to get confidence to follow their dreams and be successful.
-the burning of fossil fuel
-natural events
-waste in landfills
-agricultural activities
-mining operations
-etc
I would say diabetes because when you're diabetic you have an elevated amount of glucose. Which causes the narrowing of blood vessels and stiffening in arteries and a decrease in the function of red blood cells. which would mean that white blood cells don't do their job, and fight infection. so with all of this, blood and oxygen flow to the wound are decreased. So the wound can not receive proper attention from the body because it doesn't have enough nutrients or oxygen to heal.
