Ozone layer depletion is not a major cause of climate change. Global warming will be more significant contributor of climate change on earth.
<h3>What is ozone layer depletion and global warming?</h3>
Ozone layer depletion is the thinning of the ozone layer present in the upper atmosphere. This happens when ozone molecules interact with atmospheric chlorine and bromine atoms and break down. One chlorine molecule is capable of destroying one ozone molecule. It is not produced as quickly as it is destroyed.
The phenomenon of rising average air temperatures close to the surface of the Earth over the previous one to two centuries is known as global warming. This change has disturbed the climatic pattern of the earth. The burning of fossil fuels, logging of forests, and raising of livestock all have a rising impact on the climate and temperature of the planet. This increases the greenhouse effect and causes global warming by adding a significant amount of greenhouse gases to those that are already present in the atmosphere.
Ozone layer depletion is more acceptable than global warming because global warming is more responsible for the climate change in the earth, it traps huge amount of gases which rise the earth's temperature. Climate change may not primarily be caused by the ozone hole. Although a larger ozone hole does not contribute to global warming, the presence of ozone, a greenhouse gas, has a warming impact. The ozone hole itself has a minor cooling effect (about 2 % of the warming effect of greenhouses gases) because ozone in the stratosphere absorbs heat radiated to space by gases in a lower layer of Earth’s atmosphere. A small amount of heat can escape from that area into space as a result of the loss of ozone.

Answer:
Scientists believe that the different types we know emerged as early humans adapted to infectious diseases.
Explanation:
Different human blood types probably emerged to ward off infectious diseases. The incompatibility of some blood types, however, is only an "accident" of evolution. But this is a relatively recent problem, since blood transfusion has been around for only a few hundred years.
There are four main blood types. The oldest is B, which must have originated about 3.5 million years ago - it existed even before the human species evolved from its hominid ancestors, from a genetic mutation that modified one of the sugars in the surface of red blood cells.
Approximately 2.5 million years ago, mutations inactivated sugar, resulting in type O blood, which has neither type A nor B. sugar. AB blood, as it is easy to suppose, is covered by both sugar A and sugar by B.

Remittent fever
Remittent fever is a high body
temperature which shows fluctuations each 24-hour period but never gets to
normal. The pattern of this fever is not a distinguishable feature of any
disease. For the question given above, Mrs. Harris is describing remittent
fever.
