Pollution – Short Speech 1.
The earth that we live in today is far from its pristine and natural form. I am sure that most teachers and students here would agree with my statement.
Some of the changes that the planet has undergone have been a part of the natural and gradual process of evolution. However not all of them have been so. Many of the most recent and rapid changes have been induced by human beings. To give a more understandable name to this, we can call it pollution.
Pollution is a product of human exploitation of the environment. Man who has come on control over nature in the recent centuries, have exploited it mindless without an understanding of the consequences resulting in unexpected changes that we are trying to combat today.
We can define pollution as the introduction of contaminants into the natural environment which causes adverse change and damage to the environment. Pollution of the environment can be broken down into the pollution of the various components of the environment. There is air pollution, water pollution, land pollution, noise pollution and light pollution. Most of us are familiar with air, water and land pollution. The newer additions are noise and light pollution. Noise pollution basically refers to the excessive noise that is created by human activity from processions to industrial activity. Light pollution refers to the excessive light concentration from artificial sources. These sources of pollution are found to have negative and pervasive effects on the individual as well as the environment.
In conclusion to this speech, I would like to end by saying that we have caused harm to the environment and are suffering the consequences of the same. The problem is that it is not the ones responsible that are facing the consequences. But we can all work together to prevent the consequences from becoming worse and also to renew the environment. It is in our hands to be the change that we want in this world.

Pollution – Short Speech 2.
I feel honored to present my speech on Pollution.
Pollution is the unwanted process by which our environment becomes impure or dangerous. In our environment, there are many harmful substances or pollutants. The presence of pollutants in our natural environment such as air, water, soil, etc., makes it dangerous for living-beings.
Pollution is everywhere. There are dusts, and polluted gases in the air we breathe. The fresh water systems are mixed with impure chemicals. The soil has become contaminated and not fit for agriculture.
The causes of pollution are many. Most of them are very often related to human activities. Air is polluted when harmful gases are emitted from vehicles and factories. Loud noises of heavy machinery causes noise pollution. Contaminated groundwater, pesticides, and acid rain causes soil erosion. Untreated disposal of factory wastes has caused much harm to the fresh water bodies such as rivers, lakes, and underground water.
The effect of pollution is very bad. Breathing impure air is not safe for human health. Loud noises may damage the hearing capability of humans. The ecosystem and biodiversity of both the fresh water systems and oceans get damaged due to pollution. Water pollution may lead to scarcity of potable water. Contaminated soil is neither safe for cultivation, not it is fertile enough for crop growing in abundance. Further, massive release of greenhouse gases may give rise to environmental problems such global warming and climate change.
The solution to the gigantic problem called pollution lies somewhere the way we consume and use various things in our life. More reliance on renewable energy sources for energy generation will surely help in reducing pollution. Planting trees and supporting various afforestation projects can help in reducing pollution and soil erosion. Plants and trees also purifies the air. Organic farming is the answer to the problem of soil erosion due to the excessive use of pesticides. The fertility of the soil remains unaffected if natural manures are used.
Thus, we find that though the modern era is an era of urbanization and comforts, it has come at the cost of polluting the environment. Now, it is the time for making concrete steps towards removing or controlling the factors that cause pollution. The youth of today desires a pollution free world. And, I am sure that they are committed to make it a reality.
