What is pollution doing to the world?
Pollution is the introduction of harmful materials into the environment.These harmful materials are called pollutants. Pollutants can be natural, such as volcanic ash.They can also be created by human activity, such as trash or runoff produced by factories. Pollutants damage the quality of air, water, and land.
How do pollutants enter the water system?
One way that these pollutants enter the water system is when rainwater washes fertilizers and pollutants off crops. The rainwater then drains into wells, streams, and other water sources and causes damage.

On top of that, many mammals, birds, reptiles, and insects regulate their reproductive and developmental cycles using natural light patterns. Light pollution disrupts these cycles and can cause wildlife populations to decline.
What happens when water is polluted?
What happens in water pollution is that these chemicals and nutrients enter the water system and make it undrinkable and dangerous for plant and animal life. In turn, this affects the ecosystem of the area and kills off important organisms.
What are secondary pollutant gases?
One common type of secondary pollutant is the gases produced when car exhaust fumes rise into the air. Those chemicals react with the air we breathe to create even more harmful gases.
What are primary pollutants?
Primary pollutants are pollutants that are emitted into the air directly from their source. Most primary pollutants are associated with burning fossil fuels for transportation and electricity.

This is having an equivalent effect to that of smoking tobacco, and much higher than, say, the effects of eating too much salt. Facebook live: special talk on climate change with Arnold Schwarzenegger.
What are the two types of air pollution?
There are two main types of air pollution – ambient air pollution (outdoor pollution) and household (or indoor) air pollution refers to pollution generated by household combustion of fuels (caused by burning fuel such as coal, wood or kerosene) using open fires or basic stoves in poorly ventilated spaces.
How many people die from air pollution in the world?
Household air pollution kills 4 million people a year and tends to affect countries in Africa and Asia, where polluting fuels and technologies are used every day particularly at home for cooking, heating and lighting. Women and children, who tend to spend more time indoors, are affected the most.
What is the greatest environmental threat to health of our time?
1 / 8. Climate change → Air pollution is the greatest environmental risk to health of our time, and climate change is the greatest public health threat of the 21st century. Burning fossil fuels is the primary source of both climate-warming emissions and health-damaging air pollution.
What is the biggest environmental health risk?
Access to clean household energy → Clean household energy access must move higher on the global energy, health and climate agendas. Household air pollution is one of the world’s single biggest environmental health risk, and a significant source of climate-warming pollution.
How much air pollution is safe?
So how polluted can air be before it starts to affect our health? For PM2.5, WHO guidelines say the maximum safe level is an annual average concentration of 10 μg/m 3 or less. To encourage cities to reduce air pollution, even if they are unable to meet the ideal safe levels, WHO has set three interim targets for cities. These are: 15 μg/m 3 (interim target 3); 25 μg/m 3 (interim target 2); 35 μg/m 3 (interim target 1). Many cities are now exceeding the very upper level of interim target 1.
How do pollutants affect the environment?
As well as affecting our health, pollutants in the air are also causing long-term environmental damage by driving climate change, itself a major threat to health and well-being.
How does pollution affect humans?
We are already seeing its effects in the form of global warming, contaminated seafood, increased cases of lung diseases and more.
What diseases are caused by polluted drinking water?
Diseases such as amoebiasis, typhoid and hookworm are caused by polluted drinking water.
How does toxic air pollution affect animals?
The toxic chemicals released into the air settle into plants and water sources. Animals eat the contaminated plants and drink the water. The poison then travels up the food chain – to us.
What are the causes of air pollution?
The main cause of air pollution as well as climate change (CO2-emissions) is the burning of fossil fuels (oil, coal, gas). A change to greener alternatives such as solar or wind power will therefore help both the climate and human health.
What are the effects of mercury on water?
Water polluted by chemicals such as heavy metals, lead, pesticides and hydrocarbon can cause hormonal and reproductive problems, damage to the nervous system, liver and kidney damage and cancer – to name a few. Being exposed to mercury causes Parkinson’s disease, Alzheimer’s, heart disease and death.

Why are fish dying?
Our fish are dying. They are eating the plastics and other contaminants in the sea, mistaking it for food. It’s not just the fish through, whole marine ecosystems are being affected. The concentration of the toxic materials in our oceans can reach levels that are enough to kill all marine life.
What does less waste mean?
Less waste will mean that we will no longer have a need to dump them in our oceans. The fish will be happier and so will we. More seafood!
How do heavy metals get into the ocean?
These heavy metals get into the water either directly from the toxic wastes dumped in the ocean by factories or from the garbage dumps. When the soil absorbs these heavy metals, they will find their way into the body of water surrounding them, and eventually into our oceans.
What is zero waste?
Businesses who are going green are now adopting the Zero Waste policy. This is a philosophy that uses the cradle to cradle model instead of cradle to grave. In this model, a product or material can be recycled into a new product when it reaches end of life!
