I think heart disease is a very big problem. My own father died very suddenly of a heart attack when he was still young. Each year 7.4 million people die from coronary diseases, which are diseases of the arteries that supply your heart with blood.
climate change its going to be one of the biggest threats to humanity, we will have increased sea-levels meaning less land for peoples homes, increased drought and more poverty!
