carbon dioxide (CO2)

Trees, grasses, and other plants may produce the greenhouse gas methane. Trees and other plants may emit large amounts of methane, a greenhouse gas.

Nitrogen, oxygen and argon are the three most abundant elements in the atmosphere, but there are other key components that are required for supporting life as we know it on earth. One of those is carbon dioxide gas.

Gases in Earth’s Atmosphere Nitrogen and oxygen are by far the most common; dry air is composed of about 78% nitrogen (N2) and about 21% oxygen (O2). Argon, carbon dioxide (CO2), and many other gases are also present in much lower amounts; each makes up less than 1% of the atmosphere’s mixture of gases.

Some references include other gases on this list, such as krypton (less abundant than helium, but more than hydrogen), xenon (less abundant than hydrogen), nitrogen dioxide (less abundant than ozone), and iodine (less abundant than ozone).

The difference between air and oxygen is that oxygen is a pure chemical element, while air is a mixture, not an element.

Nitrogen gas

Earth’s atmosphere is composed of about 78% nitrogen, 21% oxygen, and one percent other gases.

Earth’s atmosphere has a series of layers, each with its own specific traits. Moving upward from ground level, these layers are named the troposphere, stratosphere, mesosphere, thermosphere and exosphere. The exosphere gradually fades away into the realm of interplanetary space.

Although we can’t see it, the air we breathe is made up of several gases. Oxygen is the most important for keeping us alive because body cells need it for energy and growth. Respiration is the term for the exchange of oxygen from the environment for carbon dioxide from the body’s cells.

Air is important for living things. People need to breathe, and so do lots of other animals—and plants! During respiration, a living thing takes in oxygen from the air and gives out carbon dioxide. This process gives animals and plants the energy to eat, grow, and live life!

In other words: we inhale, high concentrations of oxygen which then diffuses from the lungs into the blood, while high concentrations of carbon dioxide diffuses from the blood into the lungs, and we exhale.

The Main Causes of Water Pollution in the U.S.

• Runoff from Agricultural Operations. Agriculture represents one of the biggest sources of water pollution in the country.
• Runoff and Nonpoint Source Pollution.
• Industrial Activities.
• Leakage from Underground Storage and Piping.
• Leaking Sewers.
• Vehicle Emissions.
• Landfill Leakage.
• Hazardous Waste.

Keep Water Clean

1. Return used motor oil for recycling.
2. Use a commercial car wash.
3. Sweep sidewalks and driveways.
4. Fight mud.
5. Avoid using lawn fertilizers that contain phosphorus.
6. Leave an unmowed buffer next to streams and lakes.
7. Flush responsibly.
8. Use the trash, not the drain.

Easy and Effective Ways to Purify Water

1. Boiling. The simplest method to purify water is to boil it for a good amount of time.
2. Water Purifier. Alt Attribute: A. O. Smith X4+ Water Purifier.
3. Reverse Osmosis.
4. Water Chlorination.
5. Distillation.
6. Iodine Addition.
7. Solar Purification.
8. Clay Vessel Filtration.

Easy Things You Can Do To Protect Drinking Water Sources

1. Properly dispose of hazardous productsPut up signs.
2. Use and dispose of harmful materials properly.
3. Volunteer in your community.
4. Join in a beach, stream or wetland cleanup.
5. Prepare a presentation about your watershed for a school or civic organization.

If it’s on the ground, it’s in the river. As water flows over the watershed, it picks up chemicals, trash, and microbes that make their way into our water sources. Preserving the quality of our raw water sources is everyone’s responsibility.

All you need to do is follow these 7 ways to help keep lakes and rivers clean and pollutant free.

1. Use less water.
2. Keep your car repaired.
3. Use organic gardening techniques.
4. Compost and contain yard waste.
5. Deal with household chemicals and medicines properly.
6. Go sustainable.
7. Don’t litter.

PLANTS are permeated by the same gases that make up the atmosphere surrounding them: oxygen, carbon dioxide and nitrogen.

The Short Answer: Air pollution is caused by solid and liquid particles and certain gases that are suspended in the air. These particles and gases can come from car and truck exhaust, factories, dust, pollen, mold spores, volcanoes and wildfires.

The Causes of Water Pollution

• Industrial Waste. Industries and industrial sites across the world are a major contributor to water pollution.
• Marine Dumping.
• Sewage and Wastewater.
• Oil Leaks and Spills.
• Agriculture.
• Global Warming.
• Radioactive Waste.

5 Causes Of Air Pollution (And How You Can Help!)

• Vehicle Exhaust Fumes. In city environments, the leading source of air pollution is vehicle exhaust fumes.
• Fossil Fuel-Based Power Plants.
• Exhaust from Industrial Factories and Plants.
• Agricultural and Construction Activities.
• Natural Causes.
