1. **Is nature the source of people's life?** Yes, nature is the foundation of human life, providing essential resources such as air, water, food, and raw materials. It supports ecosystems that are crucial for survival and well-being. 2. **For thousands of years people lived in harmony with nature, didn't they?** Yes, for much of human history, people lived in a way that respected and worked with natural systems, relying on sustainable practices and understanding the importance of biodiversity. 3. **Has man's interference in nature increased with the development of civilization? What has it led to?** Yes, with the advancement of civilization, particularly during the industrial revolution, human interference has significantly increased. This has led to environmental degradation, loss of biodiversity, pollution, and climate change. 4. **Why did some species of animals, birds, plants disappear from the Earth?** Species have disappeared due to several factors, including habitat destruction, pollution, overexploitation, climate change, and invasive species. Human activities have accelerated these processes. 5. **What is the result of man's careless interaction with nature?** The careless interaction has resulted in severe environmental issues such as climate change, loss of biodiversity, deforestation, soil degradation, and pollution, which in turn threaten human health and livelihoods. 6. **What do you know about the Chernobyl ecological disaster?** The Chernobyl disaster, which occurred in April 1986 in Ukraine, was a catastrophic nuclear accident that released large amounts of radioactive particles into the atmosphere. It resulted from a flawed reactor design and serious mistakes made by the plant operators. 7. **What are the consequences of this tragedy?** The consequences of the Chernobyl disaster included widespread contamination of land and water, long-term health effects such as increased cancer rates among those exposed, the creation of the exclusion zone around the plant, and significant socio-economic impacts on the surrounding regions. 8. **Environmental protection is a universal concern of everyone, isn't it?** Yes, environmental protection is a global concern that affects everyone regardless of geographic location. It requires collective action to ensure a sustainable future for the planet and all its inhabitants. 9. **Has anything been done to solve ecological problems?** Yes, various initiatives have been undertaken to address ecological problems, including international agreements like the Paris Agreement on climate change, conservation efforts to protect endangered species, reforestation projects, and movements advocating for sustainable practices and policies. 10. **Is international cooperation necessary to create a system of ecological security? Why do you think so?** Yes, international cooperation is essential for creating a system of ecological security. Environmental issues often cross national boundaries, and collaboration is necessary to address challenges such as climate change, biodiversity loss, and pollution effectively. Working together enables countries to share resources, knowledge, and technologies, leading to more effective solutions.
