Well, here's a list of natural environment elements, this will give you a better idea about. The given list includes objects you see in your surroundings every day, all these objects are an integral part of our natural environment. All these domains together make up the environment. The lithosphere consists of the earth's crust. All the rocks, different layers of soil, and minerals found in the earth's crust are a part of the lithosphere. This domain facilitates the lives of forests and trees, and hence they're interdependent. The hydrosphere is the domain that comprises water bodies. Hydra means water in Latin. Hydrosphere hence includes all the forms of water bodies you can find on earth. The rivers, lakes, oceans, seas, and ponds. All of them come under the hydrosphere. The Atmosphere refers to the thin blanket of air that surrounds our planet. This thin blanket of air is held together by the gravitational force and is responsible for protecting us from harmful UV radiation. The atmosphere holds several gases in a specific ratio. Few of the major gases found in the atmosphere are oxygen, nitrogen, and carbon dioxide. The biosphere refers to all the living organisms found on mother earth. Ranging from tiny insects to the giant blue whale, all of these are a part of the biosphere. The biosphere is dependent on all the other domains since no organism on earth can survive without air, water, or soil. Hence, these domains are interdependent. What is a Manmade Environment? Man-made, the word is self-explanatory. Man-made means anything which is produced due to human kind's efforts. Anything which isn't found in the surroundings naturally is termed as man-made. The world, in which all of us live is a blend of both the natural environment and the man-made environment. Examples of Artificial Environment When you look around yourself, you'd find various objects in your home. Objects have been made out of naturally existing objects but human beings modified these objects according to their convenience. For instance, consider a door. A door is generally made out of wood. Wood comes from trees which are a part of the biosphere, however, human beings have modified the wood and transformed it into a door. This is how the artificial or man-made environment came into being. Given below are a few other man-made environment examples that would help you to get a better understanding. Our man-made environment consists of electronic elements. If you look around the house, you will find several electronic devices such as a television, fan, air conditioner, to name a few. All these electronic devices are made by human beings to make our lives more convenient. Electricity is the basic source for all these electronic devices and the electricity is produced by natural sources like wind, coal, solar. Hence artificial or man-made environment is derived from the natural environment to improve the quality of our life. Global warming Climate change such as global warming is the result of human practices such as the emission of greenhouse gases. Global warming leads to higher temperatures in the oceans and on the Earth's surface, causing melting of polar ice sheets, rising sea levels, and unnatural precipitation patterns such as flooding, excessive snow and desertification. Deforestation Species-rich forests are being destroyed, especially in the tropics, often to make room for livestock rearing, palm oil plantations, soy plantations and other agricultural monocultures. Today, about 30% of the planet's surface is covered by forests, and about 18 million hectares are destroyed each year. Almost all of this deforestation comes from logging and burning. Natural forests not only act as biodiversity reserves, they also help keep coal out of the atmosphere and oceans. Pollution There are 7 key types of pollution – air, water, soil, noise, radioactive, light and thermal and these are primary causes that affect our environment in many ways. All these types of pollution are interlinked and influence each other. Therefore we need to tackle all of them together. Pollution of air, water and soil requires millions of years to recoup. Industry and motor vehicle exhaust are the number one pollutants. Heavy metals, nitrates and plastic are toxins responsible for pollution. While water pollution is caused by oil spill, acid rain, urban runoff, air pollution is caused by various gases and toxins released by industries and factories and combustion of fossil fuels; soil pollution is majorly caused by industrial waste that deprives soil from essential nutrients. Soil Degradation Globally, food security depends on the factor whether or not soils are in good condition to produce crops. According to UN estimates, about 12 million hectares of farmland a year get seriously degraded. Soils get damaged due to many reasons. Such reasons include erosion, overgrazing, overexposure to pollutants, monoculture planting, soil compaction, land-use conversion and many more. Nowadays, a wide range of techniques of soil conservation and restoration exist, from no-till agriculture to crop rotation to water-retention through terrace-building. Global Warming Climate changes like global warming are the result of human practices like the emission of greenhouse gases. Global warming leads to rising temperatures of the oceans and the earth’ surface causing natural disasters that include flooding, melting of polar ice caps, rise in sea levels and also unnatural patterns of precipitation such as flash floods, hurricanes, wildfires, drought, excessive snow or desertification.

In conclusion, it can be said that today there are many problems related to the environment. We can also take the problem of Arol in Uzbekistan. Moreover, there are many such problems all over the world. I think we have only ourselves to blame for these problems. These problems are certainly not the only problems in the world. We can take floods, tornadoes and volcanoes to the world's problems.
