FAQs on Air and Water - 2 Class 1 Worksheet EVS
| 1. Why is air and water important for life on Earth? |  |
Ans. Air and water are essential for life on Earth because they provide the necessary elements for survival. Air provides oxygen for breathing, which is essential for the respiration process in living organisms. Water, on the other hand, is crucial for hydration, maintaining body temperature, and supporting various metabolic processes in organisms.
| 2. How does pollution affect the quality of air and water? | |
Ans. Pollution significantly impacts the quality of air and water. Air pollution, caused by the release of harmful gases and particles into the atmosphere, can lead to respiratory issues, allergies, and even cardiovascular diseases in humans and animals. Water pollution, caused by the discharge of pollutants into water bodies, can contaminate drinking water sources, harm aquatic life, and disrupt ecosystems.
| 3. What are the main sources of air and water pollution? | |
Ans. The main sources of air pollution include industrial emissions, vehicle exhaust, burning of fossil fuels, and agricultural activities. These activities release pollutants such as carbon dioxide, sulfur dioxide, nitrogen oxides, and particulate matter into the atmosphere. Water pollution can be caused by industrial discharges, sewage and wastewater, agricultural runoff, and oil spills, which introduce pollutants like heavy metals, chemicals, and pathogens into water bodies.
| 4. How can we reduce air and water pollution? | |
Ans. There are several ways to reduce air and water pollution. To reduce air pollution, we can promote the use of renewable energy sources, such as solar and wind power, which produce minimal emissions. Additionally, implementing stricter emission standards for vehicles and industries, promoting sustainable transportation options, and reducing reliance on fossil fuels can help mitigate air pollution. To address water pollution, it is important to properly treat and manage wastewater, prevent industrial discharges, implement effective agricultural practices to minimize runoff, and educate the public about responsible waste disposal.
| 5. What are the consequences of ignoring air and water pollution? | |
Ans. Ignoring air and water pollution can have severe consequences for both the environment and human health. Continued exposure to polluted air can lead to respiratory diseases, decreased lung function, and increased risk of cardiovascular problems. Water pollution can result in the contamination of drinking water sources, leading to waterborne diseases and long-term health issues. Furthermore, pollution can harm ecosystems, disrupt the balance of ecosystems, and negatively impact biodiversity. It is crucial to address and mitigate air and water pollution to safeguard our health and the environment.
