Environmental Issues: Greenhouse Gases and Waste

Environmental Issues

• Greenhouse gases are gases in the atmosphere that trap heat and make the Earth warm, like a blanket around the Earth.
• The greenhouse effect is a natural process that keeps the Earth warm, but human activities are making it stronger and causing harm.

Types of Waste

• Non-biodegradable waste is waste that cannot be broken down by nature, such as plastic and glass.
• Two examples of non-biodegradable waste are plastic bags and glass bottles.

Global Warming

• Global warming is the gradual increase in the overall temperature of the Earth's atmosphere, primarily caused by human activities.
• It is a major environmental issue that affects the entire planet.

Acid Rain

• Acid rain is a type of pollution that occurs when pollutants in the air, such as sulfur dioxide and nitrogen oxides, combine with rain and fall to the ground.
• Acid rain is caused by the release of pollutants from vehicles, factories, and other human activities.

Air Pollution

• Air pollution is the presence of harmful substances in the air, such as gases, particles, and smoke.
• Air pollution is caused by human activities, such as burning fossil fuels, industrial processes, and vehicle emissions, and can harm humans and the environment.
