Fossil fuels, such as coal, oil, and natural gas, are non-renewable energy sources formed from the remains of ancient plants and animals.

Carbon dioxide is the primary greenhouse gas emitted by human activities, primarily through the burning of fossil fuels for energy production and transportation.

Crop rotation is a sustainable agricultural practice that involves growing different crops in the same area in sequential seasons to maintain soil fertility and reduce the risk of pests and diseases.

Reduce refers to the first step in the waste management hierarchy, which aims to minimize the amount of waste generated at the source.

Taking public transportation is a sustainable transportation option as it reduces individual carbon emissions and promotes efficient use of resources.

Composting is the process of converting organic waste, such as food scraps and yard waste, into a nutrient-rich soil amendment through natural decomposition.

Fixing leaky faucets is a sustainable water conservation practice as it prevents the wastage of water due to leaks.

Recycling refers to the process of converting waste materials into new materials and objects, thereby extending their lifespan and reducing the need for raw materials.

Using energy-efficient appliances is a sustainable energy efficiency practice as it reduces energy consumption and lowers greenhouse gas emissions.

Conservation refers to the practice of reducing the amount of energy consumed, often through the use of energy-efficient technologies and behavioral changes.

Implementing a comprehensive recycling program is a sustainable waste management practice as it reduces the amount of waste sent to landfills and promotes the reuse of materials.

Reforestation refers to the practice of planting trees and other vegetation on degraded or cleared land to restore its natural ecosystem and improve its environmental conditions.

Implementing sustainable agroforestry systems is a sustainable land management practice that combines agriculture and forestry to create diverse and productive ecosystems.

Conservation refers to the practice of reducing the amount of water used, often through the use of water-efficient technologies and behavioral changes.

Harnessing solar and wind energy is a sustainable energy production practice as it generates electricity from renewable sources without emitting greenhouse gases.
