Global issues are the issues that influence the global environment,and global community including environmental ,social ,economical issues. There are the following issues that adversely affect on the world..
Economical Issues:-
- Unemployment
- Food Security
- global warming/climate change
- Gender equality
- Health issues
- Global trade/investment
- Financial crisis
Environmental issues:-
- Acid rain
- Biodiversity loss
- Water scarcity
- Deforestation
Economical issues:-
Climate change/global warming:-
A change of climate that is directly or indirectly related to human activity that alters the composition of the global atmosphere and which is in addition to natural variability over comparable time periods.
climate change is also likely to have wide ranging and mostly adverse impacts on human health.Climate change is also expected to lead to increases in the potential transmission of vector borne diseases including malaria,dengue,and yellow fever.
Food Security:-
The population of the world is increases day -by- day.And the number of hungry and needy peoples in the world has increased over the last few years.One in nine people go hungry each day.The problem is that there is no enough producing food so people don't get it and live tough hungry life.And some people don't have enough money for purchasing the food due to unemployment.
According to the world food programme (WFP),countries with the highest level of food insecurity also have the highest outward migration of refugees.And this problem is twofold: while overall hunger has steadily decreased over the past decade,there has been an increase in the number of refugees.
Health issues:-
As the number of peoples in the world is increases the health issues also increased day by day.Around the world,million of the peoples are at the risk of death due to illness.The health issues occur due to poverty,or by taking the poor quality of medicine to prevent the diseases,or due to climate change.we can control these ongoing health issues by
- By improving the quality of the products/medicines.
- By improving or endure the local health system.
- By providing the essential medicine to the health departments
- By sharing scientific expertise or technical support
Example:-
- Corona virus (COVID-19)
- Malaria
- Polio
- Tuberculosis
- Measles
- HIV
- Diphtheria
- Drug-resistant pathogens
Unemployment:-
The causes of large scale are many unemployment are many.Firstly, the population of our country and other developing countries is rising fast.Our population is increasing by a few lac each year.It becomes difficult to meet the needs of all the additional people.
Secondly, the slow economic and scientific progress of the country is perhaps the greatest cause of employment.Because of slow industrial development there are not very many large factories and industrial centers,where labourers ,skilled workers and fresh graduates can get employed.
The key to solving the problem of unemployment is proper education at the right time.when the child grows up its parents or relations or the government should provide it proper school education.
"Unemployment makes useful people useless and hopeless."
Gender Equality:-
"About half of our population is of women,so democratically speaking, they deserve all the rights and importance in society which can help them to perform their roles".
There should be a gender equality in the word ,although women make up approximately half of population there have historically been social barriers to economic and personal freedom for women.The women are as important as the men in our society. They contribution to all in social and national progress.Properly educated and trained women can be immense help to their husbands and working members of their family in every situation.Women needs equality.If any country does not have gender equality they never ever move on the way of progress.
Environmental issues:-
There are some major environmental issues...
Deforestation:-
Deforestation has many adverse effects on the environment.It changes weather and climate.
Deforestation means cutting down of trees for the conversation of a forest to non forest land.It affects the amount of water soil and moisture in atmosphere.It also contributes to decreased transpiration,which lessens cloud formation.This ultimately reduces the sources of rains.
Deforestation is a great threat to biodiversity.
Acid rain:-
Acid rain is defined as any form of participants (rain,snow,sleet or dew) that has a pH less than 5.6.It results from a process of chemical reactions involving pollution and water molecules in air.It hardly affects on our environment
- The surface and the ground water also affected by acidic rain and overcome the aqua life in the surface.
- The land as well as water ecosystem affected by acidic rain.
- It affects on the skin of human beings causes skin irritation.
- It affects the fertility of soil.
Water scarcity:-
Water security is the biggest issue that hardly affects on agricultural sector.Agriculture also happens to be the largest sub-sector of water use,as it consumes around 93% of total water resources available(surface and ground water ).So mismanagement of water affect on agriculture sector.
As with food there is enough water for each person currently living on the planet. However the access to that water is not possible for everyone.Issues such as poor infrastructure displacement,and conflict mean that many people often have to use unsafe water sources.this is a clear health and sanitation risk.
