21 de noviembre - World Pure Air Day



November 21st has been declared the World Pure Air Day. Every single time we think about the old times, we can realize how  lucky our grandparents were because they had a much  better environment and the chance to breathe cleaner air. Pure air consists of a mixture of gases in proper proportion which is good for living things, it means seventy eight percent of nitrogen, about twenty one percent of oxygen, and in very small quantities of carbon dioxide, methane, ozone, and water vapor. So, it means pure air is free from germs and harmful gases. It sounds so easy to conserve it, but the reality is that through the years, this important natural resource has been polluted and the human beings are not contributing to stop that. It is important to know that smog, greenhouse gases, and other top air polluntants are affecting  the planet and our health.

 

Air Pollution and its Effects

Air pollution is a mixture of solid particles and gases in the air. Chemicals from factories, greenhouse effect emissions, fuel burning, etc… are considered air pollutants which are extremely dangerous for human health and the  planet. According to the World Health Organization, each year air pollution is responsible for nearly seven million deaths around the world. Exposure to high levels of air pollution can cause a variety of health problems, increasing cases of respiratory infections, lung cancer, and more. The environment affected by air pollution, can damage crops and trees in different ways. Just to mention some environmental impacts, such as Global Warming, that will affect the climate of different regions, the  distribution of plants and animals, it will create disturbance in agriculture and food production, increase the melting of snow, and develop an important raise in the sea levels, in the next 50 years. On the other hand, formation of acid rain is a serious thing that affects our environment, too. Sulphur dioxide and nitrogen oxides react with water in the atmosphere producing sulphuric acid and nitric acid. These acids come down along with the rain. This phenomenon is called acid rain. It affects productivity of plants by damaging the leaves, entering the soil and affecting it. It enters the ground and river waters which causes harm to the aquatic life, too.

 

Help to Reduce Air Pollution and Maintain Pure Air in our Environment.

We have to be conscious that all of us need to contribute to help reduce air pollution. Remember, the less gasoline we burn, the better. Another suggestion could be choosing another way of  transportation, you can either take the public transportation or if you have a car, you can carpool with other colleagues, walk or even ride a bike are good choices, too. Buying local food is helping to this situation, if you buy locally  you cut down on the fossil fuels burn in transporting food  from across our countries. If we live or work near areas prone to wildfires, keep away from the harmful smoke, wear masks if necessary. And one of the most vital recommendations nowadays is to wear sunscreen, when ultraviolet radiations comes through the weakened ozone layer, it can damage your skin or you can get skin cancer. We can do many positive things to keep the air pure. Let’s get involved and start at home.
