FAQs on Poster: Our Necessities -Air, Water & Food - EVS for Class 2

1. Why are air, water, and food considered essential for life?
Ans. Air, water, and food are fundamental necessities for all living organisms. Air provides the oxygen needed for respiration, allowing cells to produce energy. Water is crucial for hydration, digestion, and various biochemical processes. Food supplies the nutrients required for growth, repair, and overall health. Without any of these three elements, survival is not possible.
2. How does air pollution affect our health?
Ans. Air pollution can lead to a variety of health issues, including respiratory diseases, cardiovascular problems, and even neurological disorders. Pollutants such as particulate matter, nitrogen dioxide, and sulfur dioxide can irritate the lungs, decrease lung function, and increase the risk of asthma and other chronic illnesses. Long-term exposure can also result in serious conditions like lung cancer and heart disease.
3. What are the consequences of water scarcity?
Ans. Water scarcity can have dire consequences, including food shortages, increased competition for resources, and heightened tensions between communities. It affects agricultural production, leading to reduced crop yields and increased food prices. Additionally, lack of access to clean water can result in health problems, such as the spread of waterborne diseases.
4. How can we ensure food security?
Ans. Ensuring food security requires a multi-faceted approach that includes sustainable agricultural practices, reducing food waste, and improving distribution systems. Supporting local farmers, investing in agricultural technology, and implementing policies that promote equitable access to food are also vital. Education on nutrition and sustainable practices can help communities become more resilient to food shortages.
5. What role does climate change play in the availability of air, water, and food?
Ans. Climate change significantly impacts the availability of air, water, and food by altering weather patterns, increasing extreme weather events, and affecting ecosystems. Changes in temperature and precipitation can lead to droughts or floods, impacting water supply and agricultural productivity. Additionally, air quality may deteriorate due to increased natural disasters and industrial activity, further threatening public health and food systems.
