The four examples of environmental sustainability include: Renewable energy: Using energy sources that are replenished naturally, like solar, wind, hydro, and geothermal power. By using renewable energy, we can reduce our dependence on fossil fuels, which contribute to climate change and air pollution. Sustainable agriculture: Incorporating farming practices prioritizing environmental protection, social responsibility, and economic viability. For example, crop rotation, integrated pest management, and agricultural conservation tillage can reduce soil erosion, water pollution, and greenhouse gas emissions. Green buildings: Involves designing and constructing buildings in a way that minimizes their impact on the environment. By using energy-efficient materials and technologies and incorporating renewable energy sources for green buildings, we can reduce carbon emissions and promote sustainable development. Waste reduction: Involves reducing the amount of waste we generate and disposing of it in an environmentally friendly way. It can include using recyclable materials such as glass bottles, wooden crates, and packaging made of compostable materials or composting food waste.
