The Environmental Issues in Science

Carbon dioxide is a greenhouse gas that traps heat in the atmosphere, contributing to climate change.

Vehicle emissions, particularly from diesel engines, are a major source of air pollution in cities.

Solar energy is a renewable energy source that harnesses the power of the sun to generate electricity.

Photosynthesis is the process by which plants, including trees, use sunlight to convert carbon dioxide and water into glucose and oxygen.

Agriculture, particularly the clearing of forests for farming and grazing, is a major cause of deforestation.

Extinction is the term used to describe the permanent disappearance of a species from Earth.

Agricultural runoff, containing fertilizers and pesticides, is a major source of water pollution.

Fragmentation is the term used to describe the process by which plastic breaks down into smaller pieces over time.

Carbon dioxide emissions from human activities are a major cause of ocean acidification.

Photosynthesis is the process by which plants use sunlight to convert carbon dioxide and water into glucose and oxygen.

Fossil fuel burning, particularly the burning of coal, oil, and natural gas, is a major cause of climate change.

Evaporation is the process by which water evaporates from the Earth's surface into the atmosphere.

Methane, produced by livestock and rice cultivation, is a major source of greenhouse gas emissions in agriculture.

Transpiration is the process by which plants lose water vapor through their leaves.

Agricultural emissions, particularly from livestock and fertilizer use, are a major source of air pollution in rural areas.
