Climate change or climate breakdown will not kill us in one foul swoop. Its more likely that as the earth heats and cools, parts of the world we currently live in become impossible to live in and won’t allow us to grow enough food to survive. This will force us to live closer to each, force lots of people to move country and mean that we will be living in tighter, cramped cities and competing for resources. Over time this could lead to more diseases spreading, more easily. As disease passes from human to human, so if we all live very close to each other, it is easier for the diseases to spread from person to person. These mass disease outbreaks, may happen multiple times, until the popluation is wiped out. If climate breakdown does not slow down, eventually crops will fail and animals may die, so in the end, humans will not survive due to a lack of food to survive on and access to clean water.
