Soil pollution is caused by industrial waste that deprives soil from essential nutrients. The redundant, ever increasing use of chemicals such as pesticides, herbicides, insecticides and fertilizers is one of the main factors causing soil pollution by increasing its salinity making it imperfect for crop bearing and adversely affecting the microorganisms present in the soil, causing the soil to lose its fertility and resulting in the loss of minerals present in the soil, thus causing soil pollution and killing off more than just the intended pest. Soil pollution occurs when soil contains chemicals that are toxic or otherwise dangerous for humans and other living things. Soil pollution can cause organ damage. The presence of heavy metals in soil in toxic amounts can cause irreversible developmental damage in children, according to the website Tropical Rainforest Animals. Although lead and mercury may be found naturally in soil, high concentrations of either metal may cause damage to the developing brains of young children, which in turn may lead to neurological problems. Humans of any age may also suffer kidney or liver damage from exposure to excessive mercury in soil.

Water pollution is caused by oil spill, acid rain, and urban runoff. The use of hazardous chemicals in manufacturing industries and agriculture cause severe water pollution as waste from these industries goes directly into nearby rivers, lakes and ponds without getting treated to remove harmful toxins and compounds. This not only affects the quality of water but also pose danger to several endangered aquatic species. Increase in the water pollution can badly affect marine life and their habitats. Poor people who do not have access to clean drinking water are forced to drink untreated water which makes them prone to water related diseases which directly affects their health. Chemicals in water such as pesticides, nitrates, lead and arsenic can be a threat to human health. Pesticides can damage the nervous system and cause cancer because of the carbamates and organophosphates that they contain. Chlorides can cause reproductive and endocrine damage. Second, nitrates are especially dangerous to babies that drink formula milk. It restricts the amount of oxygen in the brain and cause the “blue baby” syndrome. Third, lead can accumulate in the body and damage the central nervous system. Lastly, arsenic causes liver damage, skin cancer and vascular diseases. Heavy metals, nitrates and plastic are toxins responsible for pollution. Air pollution is caused by various gases and toxins released by industries and factories and combustion of fossil fuels. Air pollution is a mixture of solid particles and gases in the air. Car emissions, chemicals from factories, dust, pollen and mold spores may be suspended as particles. Ozone, a gas, is a major part of air pollution in cities. When ozone forms air pollution, it's also called smog.Some air pollutants are poisonous. Inhaling them can increase the chance you'll have health problems. People with heart or lung disease, older adults and children are at greater risk from air pollution. Air pollution isn't just outside, the air inside buildings can also be polluted and affect your health Industrialized countries have worked to reduce levels of sulfur dioxide, smog, and smoke in order to improve people's health. But a result, not predicted until recently, is that the lower sulfur dioxide levels may actually make global warming worse. Just as sulfur dioxide from volcanoes can cool the planet by blocking sunlight, cutting the amount of the compound in the atmosphere lets more sunlight through, warming the Earth. This effect is exaggerated when elevated levels of other greenhouse gases in the atmosphere trap the additional heat. |
