WHAT IS POLLUTION
Pollution is the presence in or introduction into the environment of a substance which has harmful or poisonous effects
THE EFFECTS OF POLLUTION
1. Environment Degradation
The environment is the first casualty for the increase in pollution weather in air or water. The increase in the amount of CO2 in the atmosphere leads to smog which can restrict sunlight from reaching the earth. Thus, preventing plants in the process of photosynthesis. Gases like Sulfur dioxide and nitrogen oxide can cause acid rain. Water pollution in terms of the oil spill may lead to the death of several wildlife species.
2. Human Health
The decrease in quality of air leads to several respiratory problems including asthma or lung cancer. Chest pain, congestion, throat inflammation, cardiovascular disease, respiratory disease are some of the diseases that can be caused by air pollution. Water pollution occurs due to contamination of water and may pose skin related problems including skin irritations and rashes. Similarly, noise pollution leads to hearing loss, stress and sleep disturbance.
3. Global Warming
The emission of greenhouse gases particularly CO2 is leading to global warming. Every other day new industries are being set up, new vehicles come on roads and trees are cut to make way for new homes. All of them, in a direct or indirect way, lead to an increase in CO2 in the environment. The increase in CO2 leads to melting of polar ice caps which increases the sea level and pose danger for the people living near coastal areas.
