Global health is greatly affected by factors such as pollution, changes in global and regional climate, water resource quality, food growing capacity, and ecosystem health. Poor human health in turn affects the capacity of the global population to deal with environmental changes and adapt to them. Therefore, global health plays a central role in the central role in the Earth Institute’s work to understand the adverse effects of development and to find a path that leads to a sustainable future.
Everyday we encounter chemicals, physical agents, and other substances in the air, water and soil around us, as well as in the flood we eat. Research shows a connection between our environment and our health, but we still have a long way to go in understanding what links the two. We need better information and more sophisticated tools to understand the causes of these diseases if we are to prevent.
The origin of the plastic most likely came from the ocean surface abundant with plastic pollution. This plastic pollution has grown steadily over the years. The plastic back in 1980 was mostly of polyethylene which primarily comes from plastic bags and plastic bottles. The plastic is carried around the ocean via wind and ocean currents. If these picture speak anything of meaning to you, i hope the message is clear. Do your part and pick up a piece of liter if you see some. Also a great way to help out is by participating in local stream and river cleanups in your area.
This message is also being made to say that seabirds are not the only species affected here. Numerous species are affected, and something needs to done to clean up the plastic vortex. Atleast 267 species including whales, fish, turtles, seals, sea lions and seabirds have ingested or become entangled in the debris. The sad truth is that unless something is done t clean up the mess, many more marine life species will continue to die or face unnecessary trauma. The human way of life has taken a roll on the earth. The carelessness that humans have lived by for thousands of years can no longer sustain on this planet without serious consequenses.
Water polluiton comes from a number of unique sources. Combining these points of pollution with the increase in global population in a continuously decreasing amount of clean water for plant and animal lifeon earth and increasing amount of polluted water. It is widely known that water covers almost three-quarters of the earth surface. However the large amount of pollutants than fill our water ways each year are largely unknown, such as industrial waste, urban stormwater, agricaultural runoff, various household chemicals and even nuclear waste.Industry has been responsible for chemical pollution by dumping toxic wste into river. The many sources of pollutions , along with the overpuming rivers and groundwater have caused water quality to decline nationwide. Agricultural run off has caused chemical pollution that damages the delicates aquatic ecosystems.
Air pollution
Air poluiton may be defined as the introduction into the atmosphere of any material that brings about a negative effect on plants,animals, or people. The effect can vary from lowered visibility at the grand canyon to serve pollution outbreaks which may force city residents to stay indoors.Air pollution is a very big problem in our country. A large part of air pollution comes from cars. The Environmental protection agency says, ” The most polluting activity an average person does everyday is drive their car”. Most people probably aren’t aware that they are polluting the environment. May be if everyone knew how serious this polluting problem is, then they would find ways to reduce the pollution.
This picture was taken from my apartment.On the road the dustbin is took place.Government even do not care about all this ridiculous matter.People throwing garbage here and there.Its such a threat to our environment.because its polluting the air in several ways and making our environment unhealthy. Even though sometimes government provide specipic place to put garbage but what happen-people ignore it.we should not throw all this staffs here and there to protect our environment from air pollution.
Garbage disposal
Soil pollution comprises the pollution of soils with materials, mousty chemicals, that are out of place or are present at concentrations higher than normal which may have adverse effect on humans or other organisms. It is difficult to define soil pollution exactly because different opinions exists on how to characterize a pollutant, while some consider the use of pesticides acceptable if their effect does not exceed the result, others do not consider any use of pesticides or even chemical fertilizers acceptable. however soil pollution is also caused by means other than the direct addiction of xenobiotic( man made ) chemicals such as agricultural runoff waters, industrial waste materials, acidic precipitates and radioactive fallout.soil pollution can lead to water pollution if toxic chemicals leach into groundwater, or if contaminated runoff reaches strems, lakes or oceans. Soil also naturally acontributes to air pollution by releasing voltile compounds into the atmosphere.
Vehicle pollution
Of course air pollution is mothing new and from earliest times various pollutants have posed such a threat to public health that policy makers have been forced to intervence. It consider the scientific evidence that is available on the health effects of vehicle pollution. The large majority of today’s cars and trucks travel bu using internal combustion engines that burn gasoline or other fossil fuels. The process of burning gasoline to power cars and trucks contributes to air pollution by releasing a variety of emissions into the atmosphere. Emissions that are released directly into the atmosphere from the tailpipes of cars and trucks are are the primary source of vehicularl pollution. but motor vehicles also pollute air during the processes of manufacturing, refueling, and from the emissions associated with oil refining and disturbtion of the fuel they burn.
Burning garbage
burning-garbage
Did you know? when you burb garbage in a stove,in a barrel or in a camp fire,you r creating poisions the form of large variety of toxic chemicals that are released into the air.These fall back to the earth as particals or in rain drops and contaminate the water,plants and soil and accumulate in fat of animals and fish.These toxics effectively find their way up to the food chain,into the food we eat and poisoin our bodies causing serious health concern for our children and ourselves.
