Water is used as a coolant by power plants and industrial manufacturers. This is a common cause of thermal pollution.

Noise or sound pollution is annoying, distracting and can be physically harmful.

Billboards and glaring neon signs are part of light pollution in big cities.

Do you think wind turbines are an eyesore on the landscapes?

The burning of coal is the largest contributor to the increase of carbon dioxide (CO₂) in the atmosphere.

Acid rain contains dangerous chemicals because of smoke from cars and factories.

Greenhouse gases act like a blanket over the earth, thus making it warmer. This process is commonly known as the greenhouse effect.

The Canadian company TransCanada hoped to begin building the northern section of an oil pipeline that would trek close to 2,000 miles from Alberta, Canada, to the Gulf Coast of Texas. It would double imports of dirty tar sands oil into the United States and transport it to refineries on the Gulf Coast and ports for international export.
Pollution from tar sands oil greatly eclipses that of conventional oil. The water used in the process comes from rivers and underground aquifers. It takes three barrels of water to extract each single barrel of oil. Ninety-five percent of the water used to extract the oil is so polluted that the water must be stored in large human-made pools.
The tar sands oil is underneath the world’s largest intact ecosystem, the Boreal forests of Alberta. Its biodiversity is threatened by the pipeline.
Indigenous communities have been forced off their land, but also those living downstream from the ponds have seen spikes in rates of rare cancers, renal failure, etc.
