ECOLOGY

WHAT'S ECOLOGY?
Ecology is the study of the distribution and abundance of organisms, the interaction between organisms, the interaction between organisms and their environment, and structure and function of ecosystems. Scientists who study those relationships are called ecologist.

WHY IS ECOLOGY IMPORTANT?

The purpose of ecology is to provide knowledge about the way the world works and provide evidence on the interdependence between the natural world and people. A better understanding of ecological systems will allow society to predict the consequences of human activity on the environment.
HOW TO SAVE THO WORLD
RECYCLE: Recycle as much as you can – paper, glass, plastics, cardboard, newspapers, magazines, compostable food, Re-use your plastic bags. Plastic takes over 100 years to biodegrade!
To recycle paper means not to destroy wood/trees.
REUSE: When you go shopping, reuse plastic bags from a prior trip or bring a cloth bag or backpack. Don't buy products with lots of packaging.
SAVE:
• Turn the tap off when brushing/washing! When you brush your teeth, wet the brush, then turn off the water until you need to rinse. We don't waste water.
• Don't use disposable products at all.

WHAT CAUSES POLLUTION

Pollution occurs in different forms; air, water, soil, radioactive, noise, heat/ thermal and light. Every form of pollution has two sources of occurrence; the point and the non-point sources.
 AIR POLLUTION: Air Pollution is the most prominent and dangerous form of pollution. Smoke from chimneys, factories, vehicles or burning of wood basically occurs due to coal burning; this releases sulphur dioxide into the air making it toxic.
 WATER POLLUTION: It occurs due to several factors; the industrial wastes dumped into the rivers and other water bodies cause an imbalance in the water leading to its severe contamination and death of aquatic species. Nasty and fluids products flow into the rivers, lakes and seas. Also spraying insecticides, pesticides like DDT on plants pollutes the ground water system and oil spills in the oceans have caused irreparable damage to the water bodies. Water pollution not only harms the aquatic beings but it also contaminates the entire food chain by severely affecting humans dependent on these.
 SOIL POLLUTION: Soil pollution occurs due to incorporation of unwanted chemicals in the soil due to human activities. Use of insecticides and pesticides absorbs the nitrogen compounds from the soil making it unfit for plants to derive nutrition from. Release of industrial waste, mining and deforestation also exploits the soil. Since plants can't grow properly, they can't hold the soil and this leads to soil erosion.
 NOISE POLLUTION: Noise pollution is caused when noise which is an unpleasant sound affects our ears and leads to psychological problems like stress, hypertension, hearing impairment, etc. It is caused by machines in industries, loud music, etc.
 RADIOACTIVE POLLUTION: Radioactive pollution is highly dangerous when it occurs. It can occur due to nuclear plant malfunctions, improper nuclear waste disposal, accidents, etc. It causes cancer, infertility, blindness, defects at the time of birth; can sterilize soil and affect air and water.
 THERMAL/HEAT POLLUTION: Thermal/heat pollution is due to the excess heat in the environment creating unwanted changes over long time periods; due to huge number of industrial plants, deforestation and air pollution. It increases the earth's temperature, causing drastic climatic changes and extinction of wildlife.

THE CONSEQUENCE OF POLLUTION

 ENVIRONMENT DEGRADATION : Environment is the first casualty for 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 Oil spill may lead to death of several wildlife species.
 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 diseases that can be causes 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.
 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 direct or indirect way lead to 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.
 INFERTILE LAND : Due to constant use of insecticides and pesticides, the soil may become infertile. Plants may not be able to grow properly. Various forms of chemicals produced from industrial waste is released into the flowing water which also affects the quality of soil.
 CLIMATE CHANGE: Increase of our planet's temperature. (general warming)

Pollution not only affect humans by destroying their respiratory, cardiovascular and neurological systems; it also affects the nature, plants, fruits, vegetables, rivers, ponds, forests, animals, etc, on which they are highly dependent for survival. It is crucial to control pollution as the nature, wildlife and human life are precious gifts to the mankind.
