Global warming is the phenomenon of the increase of certain gas levels in the atmosphere due to the increase in the earth’s temperature. The temperature rise is due to the greenhouse effect caused by the increased levels of carbon dioxide (CO2), Chlorofluorocarbons (CFCs), and other pollutants. This term has been observed over the past 2 or 3 centuries. The rise in global warming has brought changes in climatic patterns. Many scientists have warned that a temperature rise may bring significant social, ecological, and economic damage to society. Such damage also includes the extinction of some flora and fauna species.
CAUSES OF GLOBAL WARMING:
The causes of global warming may be natural or artificial (man-made). The following are the major causes of global warming:
- DEFORESTATION: The cutting of trees over a large area will result in deforestation. The loss of trees will gradually increase the level of carbon dioxide in the atmosphere since the plants are the main source to intake CO2 and release Oxygen (O2). This in turn results in economic imbalance and increases global warming.
- INDUSTRIALIZATION AND POPULATION GROWTH: With the advent of industrial development, there is a rapid rise in the earth’s temperature. The release of harmful pollutants into the atmosphere results in global warming. The increase in population increases the level of CO2 in the atmosphere since they exhale CO2.
- GASES PRODUCED IN AGRICULTURE: Various farming activities produce carbon dioxide, methane, and nitrous oxide. Methane is released by various resources like rice paddies, fossil fuels, cow dung. By adding the fertilizers to the land, it increases the level of nitrous oxide in the atmosphere. This leads to a rise in the earth’s temperature.
- VOLCANIC ERUPTION AND FOREST FIRE: The ash and smoke emitted during the volcanic eruption and forest fire will drastically increase the level of CO2, which in turn increases global warming.
IMPACTS OF GLOBAL WARMING ON EARTH
- MELTING OF GLACIERS: Global warming has led to the temperature rise which may bring several disadvantages to the earth. This in turn increases the melting of glaciers and thus increases sea level.
- ECOLOGICAL IMBALANCE: Increase in global warming results has affected the coral reefs that may lead to the extinction of some flora and fauna species. This creates an ecological imbalance.
- CLIMATIC CHANGES: Global warming has brought changes in climatic patterns. The monsoon failure, drought, acid rain, tsunami, floods due to heavy rainfall are some of the results of climatic changes. This will have a drastic impact on the living species of earth. The marine ecosystem is greatly affected by global warming.
- ARRIVAL OF NEW DISEASES: The patterns of heat and humidity have been greatly affected by global warming. This results in the mutation of several microbes and that mutation maybe sometimes dangerous and will result in severe diseases. The increase in temperature affects the normal healthy lifestyle of humans.
- LOSS OF HABITAT: Global warming will result in the loss of habitat for several flora and fauna species. Some of the animals have to migrate from their natural habitats or some become endangered species and indirectly it brings drastic effects on biodiversity.
HOW TO STOP GLOBAL WARMING?
Follow 3R’s Reduce, Reuse, and Recycle. Reduce the usage of devices that emits CFCs and CO2 to the atmosphere. Plant more saplings to decrease the level of carbon dioxide and thus helps in maintaining the ecological balance. Conduct many awareness programs about global warming and its impact so that people can understand. Avoid the usage of plastic bags and canes. Use energy-efficient products to save energy. So, let’ protect our earth by following these steps.
