| 1. How does deforestation impact the environment? |  |
Ans. Deforestation has various negative impacts on the environment. It leads to a loss of biodiversity as many species lose their habitats. It also contributes to climate change by reducing the amount of carbon dioxide that can be absorbed from the atmosphere. Deforestation also disrupts the water cycle, leading to changes in rainfall patterns and increased soil erosion.
| 2. What are the major causes of air pollution? | |
Ans. Air pollution is caused by various factors. The burning of fossil fuels such as coal, oil, and gas releases pollutants into the air. Industrial activities, including manufacturing and construction, also contribute to air pollution. Additionally, vehicle emissions, agricultural practices, and the burning of waste all contribute to the problem.

Ans. Pollution can have severe negative effects on human health. Air pollution, for example, can lead to respiratory problems, such as asthma and bronchitis.

Overall, pollution can reduce the quality of life and increase the risk of various diseases.

Ans. Global warming has numerous consequences. It leads to rising sea levels, which can result in coastal erosion and the flooding of low-lying areas. It also contributes to more frequent and severe weather events, such as hurricanes and heatwaves. Global warming can disrupt ecosystems, causing the extinction of certain species and altering ecological relationships. It also poses a threat to agriculture and food security, as changing temperatures and rainfall patterns can affect crop yields.
