If I believed the Earth was slowly turning into cheddar cheese, I could invoke this theory to explain a lot of things. Why is the rat population in our major cities growing so quickly? Earth cheesification is providing more rat food. Why have there been so many earthquakes lately? The cheesification of the tectonic plates has made them less resistant to sudden shifts. Why are glaciers melting? The freezing point of cheddar cheese is lower than that of water; as the Earth at the poles undergoes cheesification, the unfrozen cheese is causing a slight warming of the ice sheets from below, resulting in unusual levels of melting.
