Diseases spread by pollution. The globe is getting heated up due to the poisonous gases released by the industries, vehicles, and various types of Electronic gadgets. Recently the organization for the wild life protection warned the countries that due to the changes occurring in the temperatures 12 dangerous diseases are ready to spread. Among those diseases Cholera, Ebla, Plague and Sleeping sickness are also there.
Many disease causing germs that caused severe diseases previously are now gaining their energies again due to this global warming. If we bring down the pollution we can eradicate these diseases at least to some extent.
