Environmental service aims to safeguard and maintain the health and integrity of ecosystems, biodiversity, and natural resources for the benefit of both present and future generations.

Driving a gas-powered car contributes to air pollution and greenhouse gas emissions, which harm the environment. The other options, such as planting trees, recycling waste, and using public transportation, are all examples of environmental service.

Waste reduction refers to the practices and strategies employed to minimize the amount of waste generated. It involves reducing the consumption of resources, reusing items, and composting organic materials.

Solar energy is a renewable energy source because it is derived from the sun, which is a constantly replenished resource. Fossil fuels, nuclear energy, and natural gas are non-renewable energy sources because they are finite and cannot be replenished naturally.

Upcycling refers to the process of transforming waste materials or unwanted products into new items of better quality or perceived value. It involves creatively reusing discarded materials to create something new and useful.

Carbon dioxide is a greenhouse gas because it traps heat in the atmosphere, contributing to the greenhouse effect and global warming.

Reforestation refers to the process of planting trees in areas where forests have been lost or degraded. It aims to restore the ecological balance and provide environmental benefits such as carbon sequestration, soil conservation, and biodiversity enhancement.

Plastic is a non-biodegradable material because it does not decompose naturally in the environment. It can take hundreds or even thousands of years for plastic to break down, causing pollution and harm to wildlife.

Energy efficiency refers to the practices and technologies employed to reduce energy consumption without compromising the level of service or comfort. It involves using energy more wisely and efficiently.

Organic farming is a sustainable agricultural practice that emphasizes the use of natural methods and materials to produce food. It avoids the use of synthetic pesticides, herbicides, fertilizers, and genetically modified organisms (GMOs).

Biodiversity conservation refers to the efforts and strategies employed to protect and maintain the variety of life on Earth, including species, ecosystems, and genetic diversity. It aims to prevent the loss of biodiversity and ensure the sustainable use of natural resources.

Light pollution, noise pollution, and thermal pollution are all types of pollution that can be caused by human activities. Light pollution refers to excessive artificial light that can disrupt natural ecosystems and affect human health. Noise pollution is caused by excessive and unwanted sound that can have negative impacts on human health and well-being. Thermal pollution occurs when human activities release heat into the environment, causing changes in water temperature and affecting aquatic ecosystems.

Water conservation refers to the practices and strategies employed to reduce water consumption and minimize water waste. It involves using water more wisely and efficiently, as well as implementing measures to protect and preserve water resources.

Hydropower is a type of renewable energy source that utilizes the movement of water to generate electricity. It involves harnessing the energy of flowing water, such as in rivers or dams, to produce electricity.

Carbon capture and storage (CCS) refers to the process of capturing carbon dioxide from industrial sources and storing it underground or in other geological formations to prevent its release into the atmosphere. This technology aims to reduce greenhouse gas emissions and mitigate climate change.
