Human and other forms of life are exposed to higher level of ultraviolet which can cause damage to skin cells and sensitive tissue of the eyes than they are capable of repairing. As we know, ozone is mainly found in two region of earth’s atmosphere. Most ozone are based statistic there are 90% between 10 km -17 km above Earth surface and extended up to 50 km is resided in these layers, called it stratosphere. The remaining ozone layer is called troposphere which is lowest region of
Our planet could potentially flood if this trend does not stop. It would not only hurt the habitats of polar animals, but also endangers all of Earth’s creatures and humanity as a whole. Today’s top resources, being coal, oil, and natural gas, are terrible for humanity, animals, and plants alike. There has to be better options for the well-being of our wonderful earth. Even though fossil fuels are the world’s main source of energy and are considered to be the best option, there are cleaner, more efficient forms such as wind,
Ultraviolet light can harm plants if they are overexposed. Especially to the shortest of ultraviolet wavelengths. Although the Earth’s atmosphere filters out most of the most harmful ultraviolet wavelengths, deterioration of the ozone layer has plant scientists worried about Earth’s vegetation in the future. The ozone layer of the earth is a layer in the earth's stratosphere containing a high concentration of ozone, which absorbs most of the ultraviolet radiation reaching the earth from the sun. Ozone Is a unstable toxic gas with a pungent odor and powerful oxidizing properties, formed from oxygen by ultraviolet light.
UV Rays are rays of light coming from the sun that are invisible to the naked eye. There are various types of UV rays: UV A, UV B, UV C. Whilst UV C is harmless; UV A and UV B are harmful to humans. UV B is the most harmful to humans as the wave length is the longest out of them all, which in turn can enter deeper into human skin which cause skin cancer and sun burn when exposed for a long duration The ozone layer is a layer in the Earth’s atmosphere, which helps block UV rays from hitting earth. It is made up of O3 particles, which helps absorb energy from UV rays that come through allowing for it to not do any harm. A critical problem currently occurring in the world is that pollution is causing the amount of ozone to decrease and break down.
Cornu and Hatley first described the unique role of these molecules in absorption of ultraviolet light. In addition, the ozone layer was first discovered in 1913 by Charles Fabry and Henry Buisson (Solomon, 1999) however, the properties was first described by Dobson who invented a simple spectrophotometer that could measure the stratospheric ozone from the ground (Sivasakthivel, 2011). Ozone layer is very important for the earth in such it absorbs about 93% up to 99% of the high frequency radiations. In today’s condition, the earth is suffering a drastic depletion of this layer due to excessive release of pollutants containing chlorine and bromine gasses of chlorofluorocarbons (CFCs) and halons (Solomon, 1999). Recent studies states that these deteriorations let extra UV-B radiation to reach the earth’s surface that inhibits the reproduction of phytoplankton, organisms that make up the base of food chain.
I agree by all means with the quote. It discusses how there are holes in the ozone layer and how we can’t fix the ozone layer. Science was used as a disadvantage to solve the ozone layer depletion because it was due to chemicals like CFC’s and Halons that were released in the ozone to interfere with the ozone layer ("Halon and the Ozone Layer”). “Ozone is a form of oxygen.” ("Depletion of the Ozone Layer.”). It is known by the formula: O_3.
Solar energy is a very important and great source of renewable energy on the earth. The amount of solar energy that reaches on the earth’s surface is reduced in intensity due to several atmospheric phenomena such as reflection, scattering, absorption of radiation etc. There are several factors on which the amount of reduction depends. These are generally the wavelengths of the radiation and the path through which the solar radiation passes. The factors affecting the intensity of the direct sunlight coming from the sun are the changing weather conditions, clouds and atmospheric pollutants.
Similarly, volcanic degassing determines the state of the atmosphere and climate and influences the ways in which volcanoes erupt. Hence, throughout geological history, volcanic degassing has been crucial to planetary habitability as it evidently prevented the planet from freezing, despite lower atmospheric pressures, by generating an adequate greenhouse effect. However, volcanoes occasionally erupt cataclysmically, emitting great volumes of gas and ash into the upper layers of the atmosphere. As a result, the volcanic debris may block incoming sunlight, causing global cooling, and can thereby lead to widespread crop failure and famine. The habitable zone of the Earth is, therefore, dependant on the operation of plate tectonics, as it provides the necessary conditions for atmospheric evolution and life on
• Radioactive decay is observed to be happening in the Earth’s crust, which produces harmful gases which are radioactive in nature. These harmful gases are the second largest cause of cancer after smoking. • Apart from controlled burning that is a man-made source of pollution, wildfires also as a similar source of pollution. Same harmful effects are observed on the environment. The only difference is that this source is natural.
If the atmosphere reflects the radiation from the sun then the atmospheric temperature of the earth would be so cold which would not permit any living organisms including human beings. The atmospheric temperature should be maintained for the life. It should not go below the permissible range or above the same. But the green house is getting disturbed because of the pollutions in the atmosphere due to several reasons. One such major reason is the imbalanced concentration of CO2 in the atmosphere.
