Write an essay on Grow trees to avoid pollution.
Answers
Answer:
Trees are among the greatest natural wonder and are among the greatest gift given to man and other living things that depend on it. Trees provide us with two essential things in life these are food and oxygen. Apart from food and oxygen, trees also provide additional necessities like shelter medicine among other benefits. However, as their values continue to increase as more benefits of trees are being discovered the demand for trees have increased to satisfy the modern lifestyle. Trees benefit us in several ways; for instance, trees give us food like fruits, we also get wood from trees to make furniture. Most of the furniture in our houses is made of wood from trees.
Many medicines are derived from trees to cure diseases like fever and malaria. When trees absorb extra carbon dioxide and release oxygen, trees help in making the air clean. However, it is sad that humans continue destroying trees without realizing that they are destroying their future. The forest cover in many parts of the world is shrinking because of human activities, and lack of adequate trees has resulted in global warming. There are several ways in which people are misusing natural resources, especially trees hence harming the ecosystem, such activities like logging, clearing forest for development have negatively impacted on the environment.
With increased levels of carbon dioxide and other greenhouse gases, the climate is slowly changing as the world get warmer. The changing weather patterns have impacted negatively on us resulting in unseasonal rain. Flash floods and extremely high temperatures have become a common occurrence due to limited tree coverage. Imagine living in a world with millions of trees surrounding us, in such a world the extra carbon dioxide will be easily absorbed by this many trees, as they need the gas to make food. At the same time, more trees would mean more rain, cooler temperatures, minimizing the use of machines like refrigerators and air conditioner. Planting more trees means reducing greenhouse gases that will reduce global warming.
Planting trees is important to save the plant; trees not only remove harmful chemicals, but also help minimize greenhouses gases that cause global warming. Growing more trees would mean reducing soil erosion as they allow water to flow down into the earth below the tree. The process prevents soil from being carried away to the ocean. Growing more tree will help maintain soil fertility because it stops soil erosion especially within sloppy areas. Protecting soil fertility results to the better yield of crop hence reduce hunger all over the world.
Trees are important, and we need to grow more trees because they alter the environment by moderating the climate, improving the quality of air and reducing the stormwater runoff. Many people are yet to realize the benefits of growing more trees. The importance of tree is evident because trees act as natural habitat for animals and other species, therefore planting tree means having more benefits that come along with trees.
Trees are useful to both humans and other living organisms; they give us so much with nothing in return, they help us live in a cool environment, providing us with a charming environment that is why we need to act responsibly by growing more trees. We should condemn the destruction of trees to secure our future. When we plant more tree and care for them, we not only maintain a healthy surrounding but also reduce pollution, lower energy cost and improve the appearance of our community. That is why trees are important part of our community.

Explanation:
Air pollution is a global crisis and the major topic for this year’s World Environment Day. High concentrations of harmful gases and particles in our atmosphere negatively affects the health of humans, animals and plants. It also causes temperatures to rise, intensifying climate change.
But there’s a natural remedy: forests. Trees act as the earth’s purification system by absorbing airborne chemicals and releasing oxygen. To tackle global air pollution, we need to halt deforestation and plant billions of trees.
What causes air pollution?
Industrial human activities, such as the burning of greenhouse gases, release toxic chemicals and particles into the air. Concentrations are worse in crowded urban areas, and countries with huge manufacturing industries – such as China, India and Bangladesh – have the highest recorded levels globally.
Emissions from vehicles also contribute to poor air quality. In developing countries, deforestation and burning charcoal and wood for fuel is a driving factor. Cutting down trees not only releases CO2, but also prevents forests from purifying our air.
Many governments have an air pollution index and have set targets for ‘safe’ levels of air pollution, but almost every country is currently exceeding dangerous levels.
Why is air pollution dangerous?
According to the World Health Organization, nine out of ten people breathe polluted air. Approximately seven million deaths every year are attributed to bad air quality, which increases the risk of strokes, lung cancer and heart disease. Breathing dirty air has also been linked to immune system damage, as the body becomes inflamed to try and fight off the particles it is being exposed to.
Then there’s environmental damage in the form of global warming. This UN article explains the cause and effect chain of air pollution and climate change in more detail. Air pollution also causes acid rain, which in turn damages trees and turns soil and waterways acidic. Higher levels of black carbon and ground-level ozone can harm crop yields, worsening famine and poverty.
How do trees clean the air?
The world’s forests absorb a third of global emissions every year. Particles, odors and pollutant gases such as nitrogen oxides, ammonia and sulfur dioxide settle on the leaves of a tree. Trees absorb these toxic chemicals through their stomata, or ‘pores’, effectively filtering these chemicals from the air. Trees also mitigate the greenhouse gas effect by trapping heat, reduce ground-level ozone levels and release life-giving oxygen. If we continue with our current rate of deforestation, it will have severe consequences on the quality of our air.
Can using Ecosia reduce air pollution?
Ecosia is committed to planting trees and spreading awareness about the vital role forests play in the protection of our planet. We need to leave pristine forests intact, as they are carbon sinks and one of our biggest defences against climate change.
Every time you search the web, we use our ad revenue to plant trees where they are needed most: in deforested landscapes across South America, Africa and Asia. If you haven’t installed Ecosia on your desktop or smartphone yet, get it now and start planting trees today
