What are the characteristics of the environment?
2020 has been a strange year. With so many people forced to stay at home, the amount of pollution from driving has decreased so dramatically that it has closed the hole in the ozone layer over Antarctica according to the World Meteorological Organization (WMO).
Ozone is a pollutant at ground level, but it protects the earth from solar radiation contained in the upper atmosphere. Without ozone, the Earth would get much warmer. Ozone is a molecule of three oxygen atoms. When carbon is released into the atmosphere, it destroys ozone. One carbon molecule attracts two oxygen molecules from the O3, leaving only one oxygen molecule. This process takes one molecule of carbon and combines it with two molecules of oxygen to produce carbon dioxide, or carbon dioxide. In our joint efforts to fight the epidemic, we have accidentally repaired the hole in the ozone layer.
More than 1 billion people live in areas with severe water scarcity. Climate change is causing prolonged droughts, increasing the number of water-scarce regions, and pushing water-scarce regions to the brink of freshwater depletion.
The United Nations, through SDG 6, affirms that “clean water and sanitation” are basic human rights and encourages the private sector to take proactive steps to ensure water security. Many water-scarce places are centers of water-intensive commercial activities. Recognizing this, investors are incorporating measures to reduce water scarcity and paying stock valuation discounts to companies that make minimal efforts to address threats to water security. Water scarcity is an urgent problem, and without serious interventions, more of the world will share in the suffering caused by this crisis.
Today, the extinction of many species or the loss of biodiversity is a much discussed topic among ecologists internationally. Many species are rapidly disappearing. It is estimated that 20 to 75 species die every day due to deforestation. The loss of biodiversity is mainly due to the deterioration of life support systems. It provides the basis of life on Earth. Biodiversity means the diversity of life on Earth.
Diversity is a requirement for long-term environmental sustainability. Therefore, it is recognized that preserving its integrity is essential to preserving human life. Biodiversity includes all types of plants, animals, and microorganisms, as well as the ecosystem and ecological processes of which they are a part.
In 1950, the world produced more than 2 million tons of plastic annually. By 2015, this annual production had grown to 419 million tons and worsened plastic waste in the environment.
A report in the scientific journal Nature found that nearly 14 million tons of plastic currently enter the oceans each year, damaging the habitats of wildlife and the animals that live in them. Research has shown that if nothing is done, the plastic crisis will grow to 29 million metric tons per year by 2040. If we include microplastics, the cumulative amount of plastic in the ocean could reach 600 million tons by 2040
Ozone layer depletion:
Ozone layer depletion is a problem caused by air pollution. The ozone layer is the earth’s protective layer. The layer filters harmful solar radiation and protects the Earth’s atmosphere from the sun’s intense ultraviolet radiation. Due to the increase in carbon dioxide, the layer is damaged and harmful radiation is let in.
Due to the high percentage of Co2, the rays that enter the Earth’s atmosphere do not return. The accumulation of carbon dioxide does not allow the reflected rays to penetrate. Because of this, the temperature on Earth is increasing beyond the expected limits. (texajp_7)
