The Earth Needs You

The population of our planet is increasing constantly. The population growth, unfortunately, has many adverse effects, one of which is the pollution problems. Pollution is a process of contaminating the environment in a way that it becomes unsafe to use. The contamination usually occurs through the chemical substances; however, it is not limited to tangible effects. The pollution can also take the form of the light, sound (noise pollution), or heat. The effects of pollution are devastative.

One of the pivotal issues nowadays is the water pollution. The enlargement of the population means more trash and garbage. The rubbish dumps decay and the toxic substances permeate the soil going to the rivers and oceans. Moreover, tons of garbage is thrown directly into the water. There are even special islands for garbage in the oceans.

Even though the technological development offers various approaches to garbage utilization, most of the poor countries do not utilize innovative technologies. Thus, pollution becomes the leading cause of death in underdeveloped, low-income countries. Nevertheless, water is contaminated not only due to regular garbage utilization. The plants, factories and mills are the key pollutants of the water. The process water from factories goes to the rivers and seas in neighborhood areas. In some rivers, the water is contaminated to the critical level and is banned for use. The fish and living environment of natural ecosystems are contaminated by dangerous chemicals that cause either the death of the entire ecosystems or hurts the consumers of the contaminated products (seafood, fish, water, salt).

Another big humanity’s challenge is air pollution. Air consists of nitrogen, oxygen, water vapor and inert gases. When the typical structure of air is altered, we can observe the effects of air pollution. The primary reason of air contamination is the effect of the burning fuels. The smoke floats in the air and most people breathe it in. Further, it affects the health resulting in respiratory diseases, cancers and other problems. Another type of air pollutants are dangerous gases, such as sulfur dioxide, nitrogen oxides, carbon monoxide, and chemical vapors. Those gases undergo the reactions in the higher atmosphere layers and return to the surface in the form of the dangerous chemicals (acid rains) that ruin the living environment. Moreover, carbon dioxide and sulfur dioxide create the so-called “greenhouse effect” when the radiation is absorbed while the heat is prevented from escaping. It is a natural process.

However, the high concentration of the gases makes Earth warmer and affects the natural processes on the planet. Thus, air pollution is one of the contributors to the global warming.

The growth of population and the technological progress have imprints on the ecological stage of Earth. The extraction of natural sources, work of factories and plants, and other products of human activity result in various environmental problems. The pollution of water, air and sound has extremely negative effects on our environment. The effects of the pollution include acid rains, detrimental diseases and illnesses of people and animals, and global warming. The environmental pollution is the global problem that calls for radical actions for environment protection and rehabilitation. More than that, the problem should be resolved on a global level by the united efforts of the global community.
