What can we do about Climate Change?

We can do it!


Preventions can be taken to reduce the effects of greenhouse gases. By looking at the causes and effects of the man-made destruction, there has been catastrophic destruction that is taking place and changing the colorful and green earth to black and white, scary earth. If humans continue to behave in these directions then over a period of time there will be sudden catastrophe, which will take place on earth like tsunami (due to gradual melting of glaciers) that we human will not able to bear the effect of destruction.
So let’s all work smartly and sensibly.
Some of the simple, daily events that we can do to reduce the global warming are –

1.     Travel - drive less and car-pool in order to reduce the emission of carbon dioxide. Also, use of bicycle and a habit of walking to reduce the use of car for a shorter distance. This also gives our body some exercise.
2.     Buy local food, fresh food from farmer, don’t buy frozen food.
3.     Change of energy efficiency – a) Turn off the light when not in use.
b) reduce the use of hair-drier, c) use cloth line instead of dryer
4.     Eat less meat – more manure produced by the cows will be useful for the farmers to produce fresh food for us. Reduce eating frozen food.
5.     Planting of trees
6.     Recycle and reuse
7.     Bring awareness among your group of people you know – Family and Friends

Health Problems


Due to increase in the amount of annual rainfall, more contamination of water in the third world countries has led to mosquito-prone diseases such as malaria, sleeping sickness, etc. For examples, countries like Africa and India.

Some of the known infections have increased its severity in spreading the disease vastly among animals and humans are shown in the table below.

As we all studies in our biology classes, the bacterial diseases can be cured by antibiotics courses. Until a certain stage of the disease, depending on which disease it is. But viral disease can’t be cured even with antibiotics. This explains that the viral diseases are much more dangerous and harmful as compared to bacterial diseases.

S No.
Disease
Type of infection
Cause
1.
Avian Influenza
Viral
Usually occurs in wild birds via secretion and feces.  This disease is spread among humans from poultry.
2.
Cholera
Bacterial
It is a water-borne disease affecting people in the in the developing world. However, its bacterial once contracted to human can be a deadly.
3.
Malaria
Bacterial
This disease is transformed from one human to another by the vector, a female mosquito that sucks the human blood.
4.
Ebola
Viral
This disease occurs due to unusual pattern of monsoon/dry seasons.
5.
Plague
Bacterial
One of the oldest diseases caused by the spread of rodents and their fleas.
6.
Sleeping Sickness
Bacterial
This disease is caused by the Tsetse fly. The major source of this disease is cattle.
7.
Tuberculosis
Bacterial
Infection that is caused in lungs (major part of the body) and other organs too.
8.
Yellow Fever
Viral
Mosquitoes carry this disease. With change in temperature the disease gets spread to other new regions.

Asthma is another major health-concerned issue that is caused by the change in the global atmosphere. High amount of greenhouse gases are emitted out from more industries and leading to air-pollution. This pollution in the air is leading to allergies and difficulties in breathing; asthma.
