Environmental issues Environmental issues are the harmful effects of human activities on the environment. These include pollution, over-population, waste disposal, climate change, global warming, greenhouse effect, etc. Various environment protection programs are being practiced at the individual, organizational and government levels with the aim of establishing a balance between man and environment. Climate change is a great concern in today’s scenario. This problem has surfaced in the last few decades. Greenhouse gases are the major cause of climate change. Environmental changes have several destructive impacts such as the melting of glaciers, change in seasons, epidemics, etc. Global Warming-- The burning of fossil fuels, emissions from the automobiles and chlorofluorocarbons add to the greenhouse gases in the atmosphere. This has led to an increase in earth’s temperature causing environmental changes. This increase in temperature across the globe is known as global warming. Ozone Layer Depletion The Ozone layer is a layer of concentrated ozone gas. It protects us from the sun’s harmful ultraviolet rays. This very important layer is being destroyed by CFCs (chlorofluorocarbons), which are used in industries and everyday life The chlorine in these compounds destroys the ozone layer. The hole in the ozone layer leaves humans and wildlife exposed to the harmful UV rays resulting in several skin diseases including cancer. Water Pollution The introduction of harmful substances into rivers, oceans, lakes and ponds, which changes the physical, chemical or biological condition of water is called water pollution. The polluted water lacks oxygen and therefore the organisms die. Water is the main source of life and therefore it is our prime duty to prevent it from any kind of pollution. Air pollution is the result of emissions from the industries, automobiles, and increasing use of fossil fuels. The gaseous emissions have added to an increase in the temperature of the earth. Not only this, it had also increased the risk of diseases among individuals. Solid Waste Management Solid-waste management is defined as the discipline associated with the generation, storage, collection, transfer and transport, processing, and disposal of solid waste in a manner that it does not have a harmful effect on the environment. Deforestation is the depletion of trees and forests at an alarming rate. The trees provide us with oxygen and several raw materials, and also maintain the temperature of the earth. Due to the depletion of trees for commercial purposes, there has been a drastic change in the earth’s climate. Forests are an abode to a large number of wild animals and plants. Destruction of forests has led to the elimination of a large number of plant and animal species affecting the biodiversity. The earth’s population is increasing drastically. It is estimated to be more than seven billion. The increasing population has led to the shortage of resources. If this is the case, it will be very difficult to sustain such a huge population. The other environmental issues including pollution, waste management, deforestation, climate change and global warming are all associated with over-population. Following are some of the most common solutions to the environmental issue: Replace disposal items with reusable items. The use of paper should be avoided. Conserve water and electricity. Support environmental friendly practices. Recycle the waste to conserve natural resources. Environmental issues are a warning of the upcoming disaster. If these issues are not controlled, there will soon be no life on earth. അഖില ജെയ്‌മോൻ 4 എ ഗവണ്മെന്റ് എൽ പി സ്കൂൾ മേവട കൊഴുവനാൽ ഉപജില്ല കോട്ടയം അക്ഷരവൃക്ഷം പദ്ധതി, 2020 ലേഖനം  സാങ്കേതിക പരിശോധന - Kavitharaj തീയ്യതി: 26/ 04/ 2020 >> രചനാവിഭാഗം - ലേഖനം
