Human Ecology is the study of the relationship between humans and their environment, including the impact of human activities on the environment and the impact of the environment on human health and well-being.

Sustainable Development is a concept that aims to meet the needs of the present without compromising the ability of future generations to meet their own needs. It involves balancing economic growth, social development, and environmental protection.

Equity and social justice are fundamental components of Sustainable Development, as they ensure that the benefits of development are shared fairly and that all individuals have the opportunity to contribute to and benefit from sustainable practices.

Mitigation refers to the process of reducing the negative impact of human activities on the environment, such as greenhouse gas emissions or deforestation. It involves taking actions to minimize the causes of environmental problems.

Adaptation refers to the process of adjusting to the impacts of climate change and other environmental changes. It involves taking actions to reduce the vulnerability of human societies and ecosystems to these changes.

Solar energy is a renewable energy source that is derived from the sun's rays. It is a clean and sustainable source of energy that does not produce greenhouse gases.

Fossil fuels, such as coal, oil, and natural gas, are non-renewable energy sources that are formed from the remains of ancient plants and animals. They are finite resources that will eventually run out.

Resilience refers to the ability of an ecosystem to recover from disturbances, such as natural disasters or human activities. It is a measure of the ecosystem's ability to withstand and adapt to change.

Crop rotation is a sustainable practice in agriculture that involves growing different crops in the same area in sequential seasons. It helps to maintain soil fertility, reduce pests and diseases, and improve crop yields.

Selective logging is a sustainable practice in forestry that involves harvesting trees in a way that minimizes damage to the forest ecosystem. It involves selecting and removing only mature trees while leaving younger trees and other vegetation intact.

Recycling is the process of converting waste materials into new materials and objects. It helps to reduce the amount of waste sent to landfills and incinerators, conserving natural resources, and reducing pollution.

Compact city design is a sustainable practice in urban planning that involves creating dense, walkable, and mixed-use urban areas. It reduces the need for car travel, promotes public transportation and cycling, and creates more livable and sustainable communities.

Energy efficiency refers to the process of reducing the amount of energy consumed while maintaining the same level of service. It involves using energy-efficient appliances, improving insulation, and adopting energy-saving practices.

Using public transportation is a sustainable practice in transportation as it reduces the number of vehicles on the road, decreases traffic congestion, and lowers greenhouse gas emissions.

Water conservation refers to the process of reducing the amount of water consumed while maintaining the same level of service. It involves using water-efficient appliances, fixing leaks, and adopting water-saving practices.
