Natural resources are the treasures that nature provides to all living organisms. They include air, water, soil, forests, minerals, fossil fuels, and biodiversity. These resources are the foundation of life on Earth and are essential for survival, development, and progress. Without natural resources, human civilization cannot exist. Natural resources are broadly classified into renewable resources … Read more
1. Introduction Disasters are sudden events that cause large-scale destruction to life, property, and the environment. They may be natural (earthquakes, floods, cyclones) or man-made (fires, accidents, wars, industrial hazards). Disaster Management refers to planning, preparedness, response, and recovery efforts taken to reduce the impact of disasters. It is essential for a safe and sustainable … Read more
1. Introduction The human heart is a muscular organ responsible for pumping blood throughout the body. It supplies oxygen and nutrients to tissues and removes carbon dioxide and waste products. The heart works as a pump in the circulatory system, functioning non-stop from birth to death. On average, the heart beats 72 times per minute … Read more
