As well as improving our well-being, trees play an important role in dispersing and removing pollutants such as carbon dioxide (CO2), nitrogen dioxide (NO2) and particulate matter (PM) from the atmosphere. This has benefits both locally and globally.
How do trees help in purifying the air?
Trees may absorb some pollutants in the natural life processes common to all plants. In an exdiange of gases, plants take in carbon dioxide, convert it to food, and release oxygen. This exchange occurs through stomata or pores on the leafs surface.
Which tree purifies air the most?
Silver birch, yew and elder trees were the most effective at capturing particles, and it was the hairs of their leaves that contributed to reduction rates of 79%, 71% and 70% respectively.
Do we need trees to breathe?
Trees produce oxygen and clean carbon dioxide out of the air we breathe. Without trees, life could not continue. Trees have also proved to remove airborne particles from the air and reduce smog, thereby improving the air we breathe, and therefore, our respiratory health.

How do forests help in purifying the air Class 7?
Moreover, forests also soak in large amounts of carbon dioxide released by animals and plants during respiration, during volcanic eruptions and also by burning coal and petroleum. This way forests help in purifying the air by maintaining the right levels of carbon dioxide and oxygen in the atmosphere.
How do the trees make air fresh?
Through a process called photosynthesis, leaves pull in carbon dioxide and water and use the energy of the sun to convert this into chemical compounds such as sugars that feed the tree. But as a by-product of that chemical reaction oxygen is produced and released by the tree.

How does nature help in keeping the air clean?
The earth around us naturally provides clean air that is produced from a series of complex interactions between the land and atmosphere. Forests, for example, absorb carbon dioxide and produce oxygen. To help produce clean air, natural resources such as wetlands, trees, and soil, filter many pollutants from our air.
How do trees control pollution?
If trees are planted in large scale, the carbon dioxide gas present in atmosphere are absorbed by plants for photosynthesis. since burning of fossil fuels produce carbon dioxide so plants absorb it and help in reducing the pollution.
What gives clean air?

Vehicle emissions, fuel oils and natural gas to heat homes, by-products of manufacturing and power generation, particularly coal-fueled power plants, and fumes from chemical production are the primary sources of human-made air pollution.
What is healthy air quality?
AQI values at or below 100 are generally thought of as satisfactory. When AQI values are above 100, air quality is unhealthy: at first for certain sensitive groups of people, then for everyone as AQI values get higher.

What makes our water dirty?
Contaminants such as chemicals, nutrients, and heavy metals are carried from farms, factories, and cities by streams and rivers into our bays and estuaries; from there they travel out to sea. Meanwhile, marine debris—particularly plastic—is blown in by the wind or washed in via storm drains and sewers.

How much of Earth’s water is fresh?
In the first bar, notice how only 2.5% of Earth’s water is freshwater – the amount needed for life to survive. The middle bar shows the breakdown of freshwater. Almost all of it is locked up in ice and in the ground. Only a little more than 1.2% of all freshwater is surface water, which serves most of life’s needs.
What is the purpose of a water filter?
Water filtering is a method used to filter out undesired chemical compounds, organic and inorganic materials, and biological contaminants from water. The purpose of water filtration is to provide clean drinking water.
How do you store water in your house?
Steel and glass bottles are ideal for storing water for regular use. Avoid using regular plastic bottles as toxins could sweep in from them into your water and contaminate it, says Dr Bhavi. 4.
