EXERCISE 04:Answer the following questions after reading the text:
Q.1: How does climate change affect water availability in different regions?
Ans: Climate change causes irregular rainfall, longer droughts, and melting glaciers, which affect freshwater supply. Some areas may experience flooding, while others suffer water shortages. This uneven distribution makes it harder for people to access clean and reliable water.
Q.2: How does climate change impact biodiversity and species survival?
Ans: Climate change alters ecosystems, changes temperatures, and destroys habitats. Many species can't adapt quickly enough, leading to extinction. Animals like polar bears lose ice habitats, while coral reefs die, due to warming oceans threatening thousands of marine species.
Q.3: How is the increase in poverty an effect of the climate change?
Ans: Climate change damages crops, water sources, and livelihoods, especially in poor regions. When people lose food, homes, or jobs due to floods, droughts, or storms, they fall deeper into poverty. Recovery becomes difficult without resources or support.
Q.4: What 's climate change and what are its main causes?
Ans: Climate change is the long-term change in Earth's climate, mainly caused by human activities such as:
• Burning fossil fuels (coal, oil, gas)
• Deforestation
• Industrial pollution
• Agriculture and waste emissions
These actions increase greenhouse gases, which trap heat and warm the planet
Q.5: How does deforestation contribute to climate change?
Ans: Trees absorb carbon dioxide (CO2). When forests are cut down, this CO2 is released into the atmosphere, adding to the greenhouse effect. Fewer trees mean less carbon absorption and more warming of the Earth. Cutting down forests is caused to demolish farmlands and pastures.
Q.6: Why might people in small island nations be more affected by climate change than others?
Ans: Small islands are at high risk of sea level rise, which can flood homes, contaminate freshwater, and even make islands uninhabitable. These nations have fewer resources to fight climate disasters, making them extremely vulnerable.
Q.7: Why is the ocean both a victim and a helper in the fighi against climate change?
Ans: Victim Oceans: absorb excess heat and CO2, causing warming, acidification, and damage to marine life.
Helper Oceans: act as carbon sinks, absorbing CO2 and slowing global warming.
Healthy oceans: help regulate the climate.
Q.8: Do you think switching to renewable energy can solve all climate problems? Why or why not?
Ans: Switching to renewable energy like solar, wind, and hydro can greatly reduce greenhouse gas emissions, but not solve all climate problems alone. Other actions like reforestation, sustainable agriculture, and waste reduction are also needed. It's a combined global effort.
Q.9: What connection can you draw between climate change and poverty?
Ans: Climate change worsens poverty by damaging agriculture, housing, and health, especially in poor countries that lack resources to recover. Poor communities are less prepared for disasters and have fewer safety nets, making them more vulnerable.
Q.10: Why is climate change considered a global issue, not just a local or national one?
Ans: Climate change affects the entire planet i.e. weather patterns, oceans, wildlife, and human health across all continents. Carbon emissions in one country can impact the atmosphere worldwide. That's why it needs global cooperation to find and implement solutions.
