Environmental Interactions and Pollution: Understanding Biotic and Abiotic Factors

The video tutorial covers the interaction between living (biotic) and non-living (abiotic) factors in the environment. It explains pollution types, sources, and effects, including air, water, and soil pollution. The importance of waste management, recycling, and composting is highlighted. The greenhouse effect and global warming are discussed, along with biogas as a renewable energy source. Practical solutions to reduce pollution and manage waste are provided.
