Global Warming

Will climate change affect the safety of the food supply to such an extent that it will cause an increase in human mortality?

Nowadays, one of the most discussing and disturbing problems in the world is global

warming. There are many concerns about climate change effects on different spheres

of our life. One of the most perturbing consequences that disturbing humanity is climate change

impact on safety of the food supplies and whether it will cause an increase in human mortality or

not. Some experts' opinion is that climate change will have a positive impact on safety of food

supplies, and will not be cause of food shortage in future. However, there is a possibility that the

effect of climate change on food supply safety will cause an increase in human mortality.

First reason why human mortality might increase is food shortage caused by floods and

drought, also food price ricing that will make food hardly available for people in some countries.

We all know that climate change entails increasing of temperature all over the world. Warmer

weather cause melting of glaciers and increasing of precipitation which in turn is cause of rising

of sea level. Frequent and abundant rainfalls along with sea level rising could be a reason for

floods that will damage crops in the floods' areas. Also, increased precipitation could cause

reduction and damage of crops, because not all plants can adapt to the weather with a high

humidity; many of plants will deteriorate or make fewer harvest. Besides, melting and

disappearing glaciers will be a cause of water shortage in regions whose rivers take their water

from ice melt. At first melting glaciers will be cause of floods, but then when they will

be nearly to disappearing it will be the reason of droughts, because rivers will not be able

to provide fields and cities with water. Another cause of droughts will certainly be temperature

rising. Lester R. Brown in his book "World on the Edge" says that crop ecologists believe that

temperature rise for each 1-degree-Celsius throughout the time of plants maturation is causing

10-persent decrease of cereal harvest (47). Thus, the temperature rising will be the cause

of yield reduction that will be drive of less food availability and price ricing. According to

Nanaimo Daily News (British Colombia), Liliana Hisas states that human death will increase

because of rising food cost and its less accessibility. Consequently there is a possibility that

human mortality will increase due to food shortage and its high prices.

Another reason of increasing human mortality is poor quality of food, and its contamination

from chemicals caused by climate change. There is some evidence that food quality is

decreasing, and food become "dangerous" for people. Scientists believe temperature rising and

hot weather make
