Question Numbers: 54-58
Direction: On the basis of the given passage answer the following questions.
In recent years, there has been a growing concern over the effects of climate change on the global ecosystem. Climate change is caused by the increase in greenhouse gases, such as carbon dioxide which trap heat in the Earth's atmosphere. This results in the planet's average temperature rising which leads to various negative consequences.
One of the most notable effects of climate change is the melting of polar ice caps which leads to rising sea levels. This threatens low-lying coastal areas and island nations, as well as causes more frequent and severe flooding. Additionally, the warming of oceans leads to an increase in the frequency and severity of hurricanes, typhoons and other extreme weather events.
Climate change also has a significant impact on the world's wildlife. As temperatures rise, many species are forced to migrate to cooler regions or risk extinction. This can lead to significant disruption of ecosystem and loss of important biodiversity. For example, coral reefs are particularly vulnerable to changes in temperature and acidity and the decline of these important habitats can have far-reaching effects on marine ecosystems.
Human health is also affected by climate change as extreme weather events can cause injury, illness and death. Heat waves in particular are a main threat and are expected to become more frequent and intense in the coming decades. Additionally, air pollution which is exacerbated by the use of fossil fuels can cause respiratory problems and other health issues.
Finally, climate change also has significant economic impacts. The cost associated with repairing and rebuilding infrastructure damaged by extreme weather events can be enormous and can have a significantly adverse impact on local economies. Additionally, the effects of climate change on agriculture can lead to food shortages and price rise.
