PROTECTION AGAINST RADIATION

The Earth's atmosphere and magnetic shield protect us from cosmic radiation. Earth's magnetic shield protects us from the cosmic radiation and is strongest at the equator and weakest near the poles. The magnetic shield diverts most of the radiation around the earth

TEMPERATURE REGULATION

The earth's temperature depends on the balance between energy entering and leaving the planet’s system. The recent buildup of greenhouse gases in the atmosphere from human activities has changed the earth's climate and resulted in dangerous effects to human health and welfare and to ecosystems.

OZONE LAYER DAMAGE

Cfs, and other gases used in cooling systems and in aerosolso breaks down ozone into oxygen. In some parts of the ozone layer, this decomposition has be become common. Scientists call these the ozone holes. In these areas ultraviolet radiation does not absorb it can pass through and strike living organisms directly.

ACID RAIN

Sulfur and nitrogen oxides react with the water in the clouds to form sulfuric and nitricod acid. These fall only in the lands with precipitation. This corrosive acids, which build up in land and lakes can kill plants.

GREENHOUSE EFFECT

The greenhouse effect is the process through which heat is trapped near Earth's surface by gases. The greenhouse gases are: carbon dioxide, methane, ozone, nitrous oxide, chlorofluorocarbons, and water vapor. When sunlight reaches the earth’s surface, it can either be reflected back into space or absorbed by the earth. Once absorbed, the planet releases some of the energy back into the atmosphere as heat.

SOURCE OF NUTRIENTS

The nutrients are either transferred to animals when animals eat the plants or they are transferred back into the soil. For instance, when plants and animals die, arthropods, earthworms, fungi and bacteria in the soil break them down. Arthropods are insects such as mites.

SUSPENDED PARTICLES

The burning of fossil fuels releases co2 and other gases. It also causes tiny little gases to be suspended in the air. When there's little wind, these particles build up around big cities and industrial atmosphere. Living in an area with too many particles is related with respiratory diseases.
