Intense human presence and tourist developments is taking its toll on marine life. Heavy ocean traffic is endangering marine habitats. Reserves of oil, gas and minerals lie beneath the seafloor and pose a major threat to sensitive marine habitats and species. Pollutants on land make their way into the ocean, harming the entire marine food chain, including humans. Deforestation leading to billions of tons of carbon releasing into the Earth's atmosphere. Slash-and-burn is a primary threat to global warming. Clearing land to utilize it for farming causes the nutrients in the soil to deplete quickly which leads to more clearing. Destroying the homes and habitats for animals and people who live in the region. Logging will lead to trees running out before human necessities are met. contamination of snow, waters, and organisms with "imported" pollutants is a phenomenon of the past few decades and appears to be increasing ecosystems in this region appear to be much more open to damage from a low level of pollutants than warmer climates many organisms in this frozen region accumulate and store organic pollutants and toxic metals. animals in this area such as polar bears and even humans, may carry high pollutant concentrations from eating local foods Extreme winds in this area carry airborne pollutants over the central Arctic Basin. Smog is contributing to global warming Carbon dioxide from cars, planes, and power plants have raised levels in the atmosphere higher in the last 150 years than they have been for hundreds of thousands of years. Chlorofluorocarbons used in refrigerants and aerosol propellants are deteriorating the Earth's ozone layer. Acid rain is caused by sulfur dioxide and other chemicals released into the atmosphere. Volcanoes used to be the main source of atmospheric sulfur dioxide; today people are.
