Ecological Problems
Our planet is continually facing various environmental problems. Most of them come from the overexploitation of natural resources at such an accelerated rate that it cannot be regenerated at the same speed. All this entails a degradation of the environment as a result of abusive consumption by human beings. Human consumption is based on the acquisition of products beyond our regeneration capacities.
In this article we are going to tell you about the various environmental problems our planet faces and what their serious consequences are.
The earth is facing climate change because the temperature is getting higher and higher, and this is accelerated due to human activities, that is, we have driven humans and increased greenhouse gas emissions.
Facing it requires a global commitment, in which all countries must reduce the emission of greenhouse gases into the atmosphere. For this, it is necessary to bet on renewable energy, public transport and cars that use clean energy, and pass laws that regulate emissions from the industry.
Air pollution, that is, the presence of pollutants in the air, has both natural and man-made causes. The biggest factors that cause air pollution are: mining for the use of chemical products and the heavy machinery necessary for its development, deforestation, increased transportation related to the burning of fossil fuels, fires and the use of pesticides in agriculture.
Acid rain is a precipitation composed of water and toxic waste, especially acid from vehicles, industries or other types of machinery. To prevent this from happening, it is necessary to control polluting emissions, shut down non-compliant industries and reduce the sulfur content of fuels or promote and invest in renewable energy.

Air Pollution
Pollution is now a commonplace term that our ears are attuned to. We hear about the various forms of pollution every day and read about it through the mass media. Air pollution is one such form that refers to the contamination of the air, irrespective of indoors or outside.
A physical, biological or chemical alteration to the air in the atmosphere can be termed as pollution. It occurs when any harmful gases, dust, smoke enters into the atmosphere and makes it difficult for plants, animals , and humans to survive as the air becomes dirty. The sustainment of all things living is due to a combination of gases that collectively form the atmosphere; the imbalance caused by the increase or decrease in the percentage of these gases can be harmful to survival.
The Ozone layer considered crucial for the existence of the ecosystems on the planet is depleting due to increased pollution. Global warming, a direct result of the increased imbalance of gases in the atmosphere, has come to be known as the biggest threat and challenge that the contemporary world has to overcome in a bid for survival.
When we try to study the sources of Air pollution, we usually enlist a series of activities and interactions that create these pollutants. There are two types of sources that we will take a look, namely Natural sources and Man-made sources.
Natural sources of pollution include dust carried by the wind from locations with very little or no green cover, gases released from the body processes of living beings (Carbon dioxide from humans during respiration, Methane from cattle during digestion, Oxygen from plants during Photosynthesis).
The major outdoor pollution sources include power generation, vehicles, agriculture/waste incineration, industry and building heating systems. Smoke features as a prominent component. The smoke emitted from various forms of combustion, like in biomass, factories, vehicles, furnaces, etc.
