Chlorine, a chemical attack secondary CFCs to ozone, which is composed of three oxygen atoms, snatching one of them to form chlorine monoxide. This then reacts withoxygen atoms to form oxygen molecules, releasing chlorine molecules that break down more ozone molecules.
Given the possible solution to reduce degradation of the ozone layer is to raise awareness of not using chemical sprays that damage our planet, reuse and recycle products could help this problem.
CLIMATE CHANGE
The main direct effect of climate change on health is the increase inmortality during the "heat waves" and other extreme weather events, mainly in the elderly, children and people with chronic conditions such as cardiovascular or respiratory diseases, by their reduced ability physiological. The problem in cities is the increase in temperature causes higher concentrations of O3 at ground level thus exacerbating air pollution problems.
Many of the organisms andbiological processes associated with the spread of infectious diseases are particularly dependent on climatic variables, especially temperature, precipitation and humidity. For example, increases in expected net after the change of the geographical distribution of insect vectors would increase the potential for transmission of many diseases.
Natural disasters can’t be prevented but can be reduced byavoiding emissions, toxic waste, anything that might affect the environment influences the climate.
