https://padlet.com/215206/cfmxdbo4epsc/wish/228784902 By burning fossil fuels like oil,coal,natural gas,gasoline for our needs of energy we have been causing air pollution this occurs when harmful substances including particulates and biological molecules are introduced into earth’s atmosphere]]> 2018-02-06 18:44:03 UTC https://padlet.com/215206/cfmxdbo4epsc/wish/228784902 215206 https://padlet.com/215206/cfmxdbo4epsc/wish/228787648 when the waste that we create is collected and is then dumped into the ocean these materials can take anywhere from 2 weeks to 200 years to decompose and not only does this contaminate the water but it can also cause harm to any animals in the sea]]> 2018-02-06 18:48:02 UTC https://padlet.com/215206/cfmxdbo4epsc/wish/228787648 215206 https://padlet.com/215206/cfmxdbo4epsc/wish/228791249 when industries pollute the air with smoke or exhaust and some of the gases that are released include sulfur dioxide and nitrogen dioxide these gases can mix with the water vapor in the air and then fall back down as acid rain that can cause the soil or water that it lands on to become contaminated and toxic to both plants and animals and is even strong enough to damage buildings]]> 2018-02-06 18:53:03 UTC https://padlet.com/215206/cfmxdbo4epsc/wish/228791249 215206 https://padlet.com/215206/cfmxdbo4epsc/wish/228792433 Thermal pollution is the harmful release of heated liquid into a body of water or heat released into the air as a waste product a example of this is water being used for cooling in a power plant that then goes into the ecosystem this can cause a change on the levels of oxygen and cause negative effects on the ecosystem]]> 2018-02-06 18:54:46 UTC https://padlet.com/215206/cfmxdbo4epsc/wish/228792433 215206 https://padlet.com/215206/cfmxdbo4epsc/wish/228793742 Radioactive contamination also called radiological contamination is the deposition of, or presence of radioactive substances on surfaces or within solids,liquids or gases, were their presence is unintended or undesirable]]> 2018-02-06 18:56:54 UTC https://padlet.com/215206/cfmxdbo4epsc/wish/228793742 215206 https://padlet.com/215206/cfmxdbo4epsc/wish/228795796 these artificial light affect nocturnal animals these animals sleep during the day and are active at night light pollution alters their environment by turning night time into day these animals depend on the earth’s cycle of day and night]]> 2018-02-06 19:00:03 UTC https://padlet.com/215206/cfmxdbo4epsc/wish/228795796 215206 https://padlet.com/215206/cfmxdbo4epsc/wish/228798237 Noise pollution is the propagation of noise with harmful impact of the activity of human or animal life the source of outdoor noise worldwide is mainly caused by machines,transport and transportation systems]]> 2018-02-06 19:03:26 UTC https://padlet.com/215206/cfmxdbo4epsc/wish/228798237 215206 https://padlet.com/215206/cfmxdbo4epsc/wish/228800968 when volcanoes erupt they create a mixture of gases and particles into the air some of these particles like ash have a cooling effect because it reflects sunlight.Volcanoes also release large amounts of greenhouse gases like CO2 which have a warming effect because greenhouse gases absorb heat from the sun this energy warms the atmosphere and earth’s surface]]> 2018-02-06 19:07:21 UTC https://padlet.com/215206/cfmxdbo4epsc/wish/228800968 215206 https://padlet.com/215206/cfmxdbo4epsc/wish/228802644 Ozone is another pollutant it is a colorless toxic gas with a pungent odor and powerful oxidizing properties,formed from oxygen by electrical discharges or ultraviolet light.this type of pollution is harmful for both plants and animals it can damage vegetation and ecosystems and breathing ozone can cause multiple health problems]]> 2018-02-06 19:09:50 UTC https://padlet.com/215206/cfmxdbo4epsc/wish/228802644 215206 https://padlet.com/215206/cfmxdbo4epsc/wish/228805678 Methane is also another gas that can cause harm methane is a colorless,odorless flammable gas that is the main constituent of natural gas.It is the simplest member of the alkane series of hydrocarbons.One source of methane are cows.It is estimated that cows release anywhere from 70 to 120kg of methane per year.The negative impact that methane has on the climate is 23 times higher than carbon dioxide]]> 2018-02-06 19:14:02 UTC https://padlet.com/215206/cfmxdbo4epsc/wish/228805678 215206 https://padlet.com/215206/cfmxdbo4epsc/wish/228809008 Cosmic rays are a highly energetic atomic nucleus or other particle traveling through space at a speed approaching that of light.These high energy radiation rays normally come from outside our solar system and when these cosmic rays come into contact with earth’s atmosphere]]> 2018-02-06 19:19:03 UTC https://padlet.com/215206/cfmxdbo4epsc/wish/228809008 215206 https://padlet.com/215206/cfmxdbo4epsc/wish/228812109 Oil spills are also a big cause in water pollution one example of this is the oil spill that happened in the gulf of mexico on april 20 2010 that killed 11 people and an estimated 3.19 million barrels of oil had leaked into the gulf causing multiple types of marine live to be affected]]> 2018-02-06 19:23:56 UTC
