Vehicle emissions, particularly from cars and trucks, are a major source of air pollution in urban areas. These emissions include harmful pollutants such as carbon monoxide, nitrogen oxides, and particulate matter.

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

Recycling is the process of converting waste materials into reusable materials. This helps to reduce the amount of waste that is sent to landfills and incineration facilities.

Carbon dioxide is a greenhouse gas that traps heat in the Earth's atmosphere. This leads to an increase in global temperatures and climate change.

Extinction is the term used to describe the loss of biodiversity. This occurs when a species is no longer able to survive in its natural habitat and dies out.

Fossil fuels, such as coal, oil, and natural gas, are non-renewable resources. They are formed from the remains of ancient plants and animals and take millions of years to form.

Reforestation is the process of planting trees to restore a forest. This helps to improve air quality, reduce soil erosion, and provide habitat for wildlife.

Water pollution occurs when harmful substances are released into the water. This can come from industrial waste, sewage, or agricultural runoff.

Reducing is the process of reducing the amount of waste produced. This can be done by buying less stuff, using reusable products, and repairing items instead of replacing them.

Noise pollution occurs when loud sounds are produced. This can come from traffic, construction, or industrial activities.

Conservation is the process of protecting and preserving natural resources. This can be done by reducing pollution, protecting habitats, and managing resources sustainably.

Land pollution occurs when harmful substances are released into the soil. This can come from industrial waste, mining activities, or agricultural runoff.

Sustainability is the process of living in a way that does not harm the environment. This can be done by using renewable resources, reducing waste, and protecting natural habitats.

Light pollution occurs when light is produced in excessive amounts. This can come from streetlights, billboards, and commercial buildings.

Sustainability is the process of using resources in a way that does not deplete them. This can be done by using renewable resources, reducing waste, and protecting natural habitats.
