Conservation of Natural Resource
Nature encompasses the phenomena of the physical world, including plants, animals, landscapes, and other natural features. It provides essential resources such as food, air, and water, which are crucial for our survival. Engaging with nature through activities like hugging trees, planting, gardening, hiking, and watching sunrises and sunsets can reduce anger, fear, and stress, while increasing pleasant feelings.
Conservation of Natural Resources
Conservation involves the careful maintenance and wise use of natural resources to prevent their depletion. These resources, including soil, water, air, plants, animals, and energy, need to be maintained sustainably. Ethiopia, for example, is rich in natural resources such as gold, platinum, potash, limestone, natural gas, and coal.
Natural resources can be classified into two categories:
- Renewable Resources: These include living things and their products, which can be managed, reused, and replaced sustainably. Examples include crop plants, trees, cattle, and chickens. Notable renewable resources in Ethiopia are coffee, Walia Ibex, sunlight, and the Ethiopian Bush crow.
- Non-Renewable Resources: These are non-living resources that cannot be replaced once used. Examples include metals like gold and iron, and fossil fuels like gas, coal, and oil. Conservation efforts are crucial to prevent species extinction and protect these resources.
Food Security
Food security, as defined by the United Nations’ Committee on World Food Security, is when all people have physical, social, and economic access to sufficient, safe, and nutritious food that meets their dietary needs for an active and healthy life. Food insecurity, often rooted in poverty, can stunt growth, slow cognitive development, and increase susceptibility to illness. Biology plays a crucial role in addressing food security by producing high-nutrient staple crops and developing new products to combat malnutrition
