| 1. What are some of the major causes of Earth's changing climate? |  |
Ans. Some of the major causes of Earth's changing climate include deforestation, industrialization, burning of fossil fuels, and greenhouse gas emissions. These activities contribute to the increase in atmospheric concentrations of greenhouse gases, leading to global warming and climate change.
| 2. How does deforestation affect the Earth's climate? | |
Ans. Deforestation significantly impacts the Earth's climate as it reduces the number of trees that absorb carbon dioxide from the atmosphere through photosynthesis. With fewer trees, there is an increase in the concentration of carbon dioxide, a greenhouse gas, leading to the greenhouse effect and global warming.
| 3. What are the consequences of climate change on Earth's ecosystems? | |
Ans. Climate change has several consequences on Earth's ecosystems. It can lead to the loss of biodiversity, as some species may not be able to adapt to rapidly changing conditions. Rising temperatures can also cause shifts in habitats and disrupt the delicate balance of ecosystems, affecting the availability of resources for different species.
| 4. How does industrialization contribute to Earth's changing environment? | |
Ans. Industrialization contributes to Earth's changing environment through various factors. The burning of fossil fuels for energy production releases large amounts of carbon dioxide and other greenhouse gases into the atmosphere. Industries also produce pollutants that can lead to air and water pollution, impacting the overall health of the environment.
| 5. What are some measures that can be taken to mitigate the effects of climate change? | |
Ans. Some measures to mitigate the effects of climate change include transitioning to renewable energy sources, reducing greenhouse gas emissions, promoting sustainable agriculture, preserving forests, and adopting energy-efficient technologies. International cooperation and policy changes are also crucial in addressing climate change on a global scale.
