Cutting down large numbers of trees in forests is known as Deforestation. It affects an ecosystem drastically. Deforestation is one of the major causes of environmental imbalance.
Urbanization refers to the population migration from rural to urban areas. In the contemporary world, urbanization has become a popular trend. The main reason for urbanization is more job opportunities and a better standard of life.
How urbanization results in deforestation?
Urbanization can result in deforestation in many ways. Two examples of which are-
- First, when rural-urban migrants adopt city-based lifestyles, they prefer to make use of more capital, as their income increases. This, in effect, drives land clearing for grazing livestock and forage.
- Meeting the food needs of a growing and urbanizing global population requires additional cropland and thus again results in deforestation.
Ozone Layer Depletion
The basic cause of ozone layer depletion is the presence of chlorine-containing gases (primarily CFCs and associated halocarbons). In the presence of UV light, these gases dissociate(breakdown), releasing chlorine atoms, which then go on to catalyze(increase the rate of a chemical process resulting in) ozone depletion.
Ozone Layer and Global warming
Due to deforestation and urbanization, the percentage of greenhouse gases increase this provides suitable conditions for the CFCs to deplete the ozone layer. The heat coming from the sun is reflected back after hitting the earth’s surface but the greenhouse effect reduces the heat from escaping the earth. Greenhouse gases like CO2 trap(absorb) heat, in turn, heating the earth’s surface but this has an opposite effect in the stratosphere as heat is trapped near the earth’s surface. The colder environment near the stratosphere supports the process of ozone depletion. This way human activities like deforestation and urbanization result in the depletion of the ozone layer.
Acid rain is caused by a chemical reaction that starts with the release of compounds such as sulfur dioxide and nitrogen oxides into the air. Such compounds can rise very high up into the atmosphere, where they combine and react with water, oxygen, and other chemicals to create more acidic contaminants called acid rain.
Harmful effects of Plastic Bags
Bags made from polythene have adverse environmental effects. Polythene bags are one form of non-biodegradable plastics that cause environmental pollution. They undergo a process known as photodegradation, in which they break down into smaller poisonous particles.
This proves disastrous to Wildlife. Plastic bags can choke fish, animals, and birds or poison them, marine wildlife is especially vulnerable to these toxic agents. "If seabirds, marine mammals or fish eat plastic particles, blocking the gut is likely to harm or even kill the organism”.
What are those fossil fuels?
Fossil fuels are rock-like, gas-like, or liquid-like resources that are burned to produce energy. They include coal, natural gas, and oil, and they are used as a source of energy in the electricity and transport sectors. They're also a big cause of emissions from global warming.
Global warming emissions
The disastrous effect of natural gas is not only produced when they are burned at power plants or in our homes as fuel. The full effect of natural gas on global warming also involves methane emissions from drilling wells and transporting pipelines.
Burning fossil fuels
Some of the largest hidden costs of fossil fuels come from air pollution that occurs when it is burned. Fossil fuels when burned release both carbon dioxide and other toxic air pollutants. The burning of Fossil Fuels like coal, oil, and natural gas may have very different types of impacts on the environment, such emissions result in a wide variety of public health and environmental costs being borne locally, regionally, nationally, and internationally.
Ways to Protect our Environment
Afforestation is the method of planting trees, or sowing seeds, to establish a forest in a barren land devoid of any vegetation. This is the converse process of deforestation. Afforestation can help in reducing Global Warming.
Reduce Paper Waste
Industry experts indicate that about 24 trees are needed when using chemical pulping to produce 1 ton of printing paper. The 24 trees will have to be a mixture of softwoods and hardwoods, with a diameter of about 6-8 inches each about 40 feet tall. This can be avoided by printing less and using the soft copy of data to process daily life Human necessities.
The 5 R’s for the environment
The five R's of the environment are refuse, repurpose, reduce, reuse, and recycle. All the above five ways help to reduce the amount of waste that we throw away. They preserve the natural resources, space for landfills, and electricity. Moreover, these also help in saving land and money which was before being used to dispose of waste.
To lessen the use of products that can harm the environment.
To use a used item again in order to reduce waste.
Refuse to buy or sell items that can harm the environment.
Recycle the items that can be reproduced like paper, plastic, glass bottles, etc.
To but something and use it for a different purpose
Disaster management can be defined as organizing and managing resources and responsibilities to address all humanitarian aspects of emergencies, in particular preparedness, response, and recovery, in order to lessen the impact of disasters.
