ACID RAIN, THEIR IMPACTS AND BIOTECHNOLOGICAL APPROACHES FOR MANAGEMENT
Acid rain is one of the major environmental threats since 19th century. The effect of acidification has been sighted all over the world such as deleterious ecological effects such as reduced reproduction of aquatic fish species, dieback and stunted growth in plants, accumulation of toxic aluminium and heavy metals in soil and water bodies, biodiversity loss including corals and shellfish, degrade to the manmade structures made up of marble and stone and corrosion of metal structures.
The term acid rain was coined in 1852 by Scottish chemist Robert Angus Smith, according to the Royal Society of Chemistry, which calls him the "father of acid rain."
Pollution
Pollution is the introduction of contaminants into the natural environment that cause adverse changes. There are three main types of pollution: air, water, and land pollution. Air pollution occurs when harmful substances are added to the air, affecting human health and contributing to issues like climate change. Water pollution happens when toxic substances contaminate bodies of water, threatening biodiversity, food safety, and access to clean water. Land pollution deteriorates the earth's surfaces through the accumulation of solid and liquid waste in soil and groundwater, endangering habitats, water quality, and public health.

The document also explains how chlorofluorocarbons depleted the ozone layer and the subsequent ban on their use. Deforestation reduces forests' ability to absorb carbon while desertification diminishes land productivity.
Acid rain
Acid rain is caused by sulfur dioxide and nitrogen oxide emissions from human sources like power plants and vehicles reacting in the atmosphere and falling to earth as rain, snow, or dry particles with a pH lower than 5.6. It damages aquatic ecosystems, soils, infrastructure, and is linked to health issues. Prevention methods include installing pollution controls on industry smokestacks, transitioning to renewable energy, restoring damaged environments, and international agreements to reduce emissions. Individual actions like conserving energy and choosing low-emissions transportation can also help address the problem.
Air pollution its causes and effect
Air pollution harms human health, plants, animals, and ecosystems. Some pollutants fall to Earth as acid rain, damaging crops, forests, and aquatic environments. Most air pollution comes from burning fossil fuels for energy and transportation, releasing compounds such as carbon dioxide, carbon monoxide, nitrogen oxides, and sulfur dioxide. Incompletely burned fuels also release volatile organic chemicals while decomposing garbage emits methane. Air pollution can travel long distances and harm distant environments. It causes breathing issues and cancer in humans as well as global warming effects.
Global environmental issues for ES
Acid rain is caused by sulfur and nitrogen oxides dissolving in rainwater to form acids that harm both the environment and human health. It damages forests, crops, aquatic species and infrastructure.

This presentation shows the amount of waste being produced is causing the environment to be weak and that the green house affect is causing global warming. Which will mean that most animals living in north and south pole e.g polar bears are going to be affected as snow is be melting. extinction
Air pollution
Air pollution is the introduction of harmful substances into the atmosphere, which can cause health issues and environmental damage. It is caused by the burning of fossil fuels like coal and petroleum, which release nitrogen, sulfur, and particulate matter. This can produce smog and acid rain. Regular inhalation of these polluted air can increase risks of diseases like asthma, COPD, and lung cancer. Governments have made efforts to reduce sulfur dioxide emissions with some success, but air pollution remains a threat, especially to children and the elderly. Reduction efforts include embracing cleaner transportation, fuels, production, and increasing green spaces.
