Climate Change
Climate change is a long term change in the Earth’s climate, especially a change due to an increase in the average atmospheric temperature.

Conditions when the effects of materials are harmful
Many attempts to save the world from global warming by removing carbon dioxide from the atmosphere but other factories continue burning fossil fuels that is why they can’t prevent the ocean from dying as a result of a build-up of acidity.

GLOBAL WARMING AND GREENHOUSE EFFECT

GLOBAL WARMING AND GREENHOUSE EFFECT
Forest fires were reported to have occurred in the Philippines., Indonesia and other countries hit by a phenomenon called El Niňo.

GLOBAL WARMING AND GREENHOUSE EFFECT
When fires like this happen, the burning trees releases excessive amount of carbon dioxide into the air. Large amount of this gas prevent heat reflected to Earth from escaping into the outer space. This phenomenon is called greenhouse effect.

Conditions when the effects of materials are harmful
GLOBAL WARMING AND GREENHOUSE EFFECT
It traps heat from the environment. It causes air temperature to rise. This condition results in the abnormal rise of the Earth’s temperature popular known as global warming.

ACID RAIN FORMATION
When fuels such as firewood and gasoline used in motor are burned, CO2, sulfur oxide and nitrous oxide are released into the air. Combined with water vapor, these gases form acid solution, known as acid rain.

ACID RAIN FORMATION
Acid rain can corrode stone buildings and status made of limestone or calcium carbonate. Acid rain also washes away top soil and reduces the production of crops. Being harmful, it can also contaminate rivers, dams and water.

THINNING OF OZONE LAYER
The ozone layer protects the Earth from the harmful effects of sun’s ultraviolet rays. The thinning of ozone layer is caused by chlorofluorocarbons or CFC’s.

Conditions when the effects of materials are harmful
THINNING OF OZONE LAYER
CFC’s are contained in hair sprays, air conditioners, refrigerators and other man made materials.

THINNING OF OZONE LAYER
Thinning of ozone layer means getting in touch with UV rays. Too much exposure to UV rays causes sunburn and skin cancer.
