As many as 153 million lives could be saved if carbon emissions were cut. To conduct this study, professor of Earth sciences Drew Shindell and Greg Faluvegi ran computer stimulations of future emissions of carbon dioxide and associated pollutants such as ozone and particulate matter under three different scenarios. Scenario 1 simulated the effects of having accelerated reduction of carbon emissions and almost no negative emissions over the remainder of the 21st century. Scenario 2 simulated the effects of allowing slightly higher carbon emissions. The final scenario simulated the effects in which near term emissions are reduced to a level that would limit atmospheric warming to 1.5 degrees Celsius.
Many premature deaths linked to air pollution could be avoided worldwide this century if governments speed up their timetable fro reducing fossil fuel emissions.
More Arctic sea ice is entering the North Atlantic Ocean than before, making it increasingly dangerous for ships to navigate those waters in late spring, according to new research.
Many boats, for example fishing boats, have been getting trapped in the multiyear sea of ice off the Newfoundland coast.
The tributyltin (TBT) released by antifouling paints has resulted in sea water pollution. This has lead to serious consequences on the oyster production in many bays along the French coastline. The influence of the ban on tributyltin use in antifouling paints on the recovery of the oyster stock is discussed in an attempt to reflect on the strategy required to protect the marine environment.
The TBT in France has greatly effected the oyster population as well as marine life in general. Without marine life, our lives will change completely. We will have less food, less beauty, and less money. About 70% of our world will become a desert/ trash dump. Since water is a large component of all known living cells, every plant, animal, fungus, etc., every living thing on Earth would die. With all water vapor gone from the atmosphere, the sky might change color, and become a reddish tint due to the high oxygen content.
Pollution is defined as the introduction into the environment of a substance or thing that has harmful or poisonous effects. Pollution of air, water and soil require millions of years to recoup. Manufacturing and motor vehicles are the number one cause of pollution. Environmental pollution is one of the worlds greatest problems. It is causing irreplaceable damage to the natural world as well as human society. Forty percent of human deaths worldwide is caused by water, air, and soil pollution.
Breathing polluted air puts you at a higher risk for asthma and other respiratory diseases. Long term health effects can include chronic respiratory disease, lung cancer, heart disease, and even damage to the brain, nerves, liver, or kidneys. Continual exposure to air pollution affects the lungs of growing children and may aggravate or complicate medical conditions in the elderly.
Forests cover about 30% of our planet, however deforestation is rapidly clearing these essential habitats. At the current rate of deforestation, the worlds rain forests will vanish within the next hundred years. The biggest cause of deforestation is agriculture. This is because farmers cut large areas of forests to make room to plant crops and to graze their livestock. Logging operation are also at great fault for deforestation. Logging operations provide the world's wood and paper causing them to cut countless trees a year. Although deforestation is greatly caused by humans, it is also caused intentionally. Some are caused by wildfires and overgrazing, which prevents trees from growing. 80% of Earth's land animals and plants live in forests and deforestation is causing millions of these species their habitats.
Trees play an important role in absorbing greenhouse gases. With all the trees being cut down, there will be a great increase of greenhouse gases in entering our atmosphere which will cause an increase speed of global warming. The amount of deforestation could be lowered by decreasing the number of trees being cut down and replacing the trees by planting new ones.
Our large amounts of trash has a significant affect on people, animals, and the environment everywhere. Some might think that their waste is being thrown into a landfill or maybe a recycling facility, however the sad truth is that most of our waste ends up being spread around the globe by wind, water, or human. Much of this problem lies in our need for continuously cheaper goods made from unsustainable products. Plastics are ingested by birds, fish, and numerous other animals whether from the ocean or in other natural environments. This causes long term effects to the animals higher on the food chain. BPA, phthalates, vinyl
chloride, dioxin, and styrene are all chemicals found in plastics proven to be harmful to both human and animal bodies.
All of this hazardous waste is extremely harmful to humans for multiple reasons. one reason includes the fact that it is a hazard to the human health and environment which includes our soil, air, and water. With our natural resources being mixed with an abundant amount of waste, it is only a matter of time before we run out of our much needed resources.
Supermarkets spend, on average, 50 to 60 percent of their energy bills on refrigerating food and cooling people. This puts them among the biggest commercial building electricity users. This is a major environmental problem because it will substantially warm the Earth's atmosphere. According to John Fialka, supermarkets use about 2.5 million kilowatts-hours of electricity per year. Supermarkets leaking refrigerants have been blamed fro destroying the Earth's ozone layer. The ozone layer protects people from harmful solar radiation.
If the earths atmosphere keeps getting warmer, the ecosystem will collapse. Mountain glaciers and rivers will start to disappear. Most importantly, life on Earth will face extinction. If the ozone layer is destroyed we will face numerous consequences. Increase in sunburn, skin cancer, cataracts, and damage to plants are all suspected consequences. For these reasons, supermarkets should reduce their usage of refrigeration.
If ocean temperatures continue to rise due to climate change, fish will shrink by 30 percent. As fish grow they begin to demand more oxygen because their body mass becomes larger. However, the surface area of the gills grows much slower. Warmer waters increase fish's need for oxygen. Climate changes will prevent the oceans from getting enough oxygen needed for marine organisms. Lack of oxygen prevents the gills from giving enough oxygen to supply the body. Researches say this causes fish to stop growing. Fish are then unable to fulfill their needs with limited oxygen. Fast moving fish, such as tuna, require more energy and oxygen which means that they may be more affected by these factors.
If fish continue to shrink and later become extinct the planet will experience drastic changes. We will loose a major food source which will impact many especially the people who are unable to afford chicken or red meat. If fish become unavailable, it would increase poverty, malnutrition, and starvation. The ocean will not be able to perform many of its essential functions and there would be no marine life to keep pollution under control.
