Answer:
Deforestation
Deforestation is the permanent removal of trees to make room for something besides forest. This can include clearing the land for agriculture or grazing, or using the timber for fuel, construction or manufacturing. Forests cover more than 30% of the Earth's land surface, according to the World Wildlife Fund.
Urbanization
Urbanization refers to the increasing number of people that live in urban areas. It predominantly results in the physical growth of urban areas, be it horizontal or vertical. The United Nations projected that half of the world's population would live in urban areas at the end of 2008.
Oxygen reduction and Pollution
Water pollution has caused the ecosystem to be in a state of imbalance for a long time. It has become a major global ecological and environmental problem today. Solving the potential hidden dangers of pollutants and avoiding unauthorized access to resources has become the necessary condition and important task to ensure the sustainable development of human society. To solve such problems, this review summarizes the research progress of nanomaterials in the field of water aimed at the treatment of water pollution and the development and utilization of new energy. The paper also tries to seek scientific solutions to environmental degradation and to create better living environmental conditions from previously published cutting edge research. The main content in this review article includes four parts: advanced oxidation, catalytic adsorption, hydrogen, and oxygen production. Among a host of other things, this paper also summarizes the various ways by which composite nanomaterials have been combined for enhancing catalytic efficiency, reducing energy consumption, recycling, and ability to expand their scope of application. Hence, this paper provides a clear roadmap on the status, success, problems, and the way forward for future studies.
Deforestation is the cutting down of trees in the forest in a large number. Deforestation has always been a threat to our environment. But still many humans are continuing this ill practice. Moreover, Deforestation is causing ecological imbalance. Yet, some selfish people have to fill their pockets. Therefore they do not even think about it once. So, the government is trying countermeasures to avert the harm to the environment.
Essay on Deforestation
The main purpose of deforestation is to increase the land area. Also, this land area is to set up new industries. And, this all is because of the increase in population. As the population increases the demand for products also increase. So rich businessmen set up these industries to increase profit.
Harmful Effects of Deforestation
There are many harmful effects of deforestation. Some of them are below:
Soil erosion: Soil erosion is the elimination of the upper layer of the soil. It takes place when there is removing of trees that bind the soil. As a result wind and water carries away the top layer of the soil.
Moreover, disasters like landslides take place because of this. Furthermore, soil erosion is responsible for various floods. As trees are not present to stop the waters from heavy rainfall’s gush directly to the plains. This results in damaging of colonies where people are living.
Global Warming: Global warming is the main cause of the change in our environment. These seasons are now getting delayed. Moreover, there is an imbalance in their ratios. The temperatures are reaching its extreme points. This year it was 50 degrees in the plains, which is most of all. Furthermore, the glaciers in the Himalayan ranges are melting.
As a result, floods are affecting the hilly regions of our country and the people living there. Moreover, the ratio of water suitable for drinking is also decreasing.
Impact on the water cycle: Since through transpiration, trees release soil water into the environment. Thus cutting of them is decreasing the rate of water in the atmosphere. So clouds are not getting formed. As a result, the agricultural grounds are not receiving proper rainfall. Therefore it is indirectly affecting humans only.
A great threat to wildlife: Deforestation is affecting wildlife as well. Many animals like DodoSabre-toothed Cat, Tasmanian Tiger are already extinct. Furthermore, some animals are on the verge of extinction. That’s because they have lost habitat or their place of living. This is one of the major issues for wildlife protectors.
