Study Notes
Importance of Water
- Water is essential for human survival, making up approximately 60% of an adult's body weight
- It is necessary for various bodily functions, such as regulating body temperature, transporting nutrients, and removing waste products
Water Scarcity
- Only 2.5% of the Earth's water is freshwater, and most of it is frozen in glaciers or stored underground
- Approximately 1 billion people worldwide lack access to clean drinking water
- Water scarcity affects 40% of the global population, with this number expected to increase due to climate change and population growth
Water Uses
- Agriculture: 70% of global freshwater is used for irrigation, with 30% of this water being wasted due to inefficient practices
- Industry: 20% of global freshwater is used for industrial processes, such as manufacturing and energy production
- Domestic: 10% of global freshwater is used for household purposes, such as drinking, cooking, and sanitation
Water Conservation
- Every day, the average person uses around 80-100 liters of water
- Simple actions, such as fixing leaks and using water-efficient appliances, can save up to 30% of daily water usage
- Implementing water-saving technologies, such as drip irrigation and rainwater harvesting, can also reduce water waste
Water Pollution
- 80% of wastewater worldwide is released into the environment without adequate treatment
- Water pollution affects human health, causing an estimated 3.4 million deaths annually
- Common water pollutants include:
- Chemicals from agricultural runoff and industrial processes
- Bacteria and viruses from human and animal waste
- Heavy metals and other hazardous substances
Sustainable Water Management
- Implementing sustainable water management practices, such as water reuse and recycling, can help reduce water scarcity
- Protecting and restoring natural habitats, such as wetlands and forests, can help maintain water quality
- Educating individuals and communities about water conservation and pollution prevention is crucial for promoting sustainable water management practices
