What are Environmental Issues?
Environmental issues are the harmful effects of all human activities. Some of the global environmental issues include pollution, overpopulation, waste disposal, climate change, global warming, the greenhouse effect, etc.
To create a balance in the environment, many government and non-government organizations follow protection programs on individual and organizational levels. Let’s look into some of the environmental issues that need urgent attention:
Climate Change
In today’s world, climate change poses a great threat and is one of the major environmental issues. The issue has come up in the last few decades. Release of greenhouse gases due to burning fossil fuels, deforestation and industrial activities is one of the major causes of climate change. This change has led to various problems such as the melting of glaciers, changes of seasons and an increase in epidemics.
Global Warming
The release of gases by burning fossil fuels and using automobiles has added high amounts of CFCs and greenhouse gases in the atmosphere. It has caused an increase in the temperature of Earth leading to Environmental issues. The increase in Earth’s temperature around the world is called global warming. Global warming is one of the current environmental issues that have come up in the past few decades.
Ozone Layer Depletion
The ozone layer is a protective layer around Earth that protects everyone from the harmful UV rays of the sun. The release of CFCs through various appliances has led to the depletion of the ozone layer. The chlorine present in CFCs destroys the ozone layer. The depletion of ozone leaves humans and other wildlife exposed to the harmful UV rays of sun, which results in various skin issues including cancer.
Ozone depletion is a leading cause of increasing environmental issues and concerns and requires immediate attention.
Air Pollution
Air Pollution is another important environmental concern in today’s world. It is a result of emissions from industries, vehicles, and use of fossil fuels. The harmful emissions have led to an increase in the temperature of the Earth. It has also resulted in an increased risk of diseases among people.
Water Pollution
The release of harmful chemicals and substances into the rivers, oceans, lakes, and seas by industries has resulted in changes in the chemical, physical, and biological environment of water bodies. This harmful change is known as water pollution.
Water is the main source of life for all living organisms and polluted water hampers the life of many living organisms as it lacks oxygen. Water pollution is one of the global environmental issues, hence, it is important to prevent water pollution.
Solid Waste Management
Solid waste management includes the collection, treatment, and disposal of solid waste that is discarded as unwanted and useless. Its effective management aims to prevent the negative impact of waste on health and the environment. Solid waste management, if followed properly, might prevent the worsening of the current environmental issues.
Deforestation
Deforestation is the removal of large-scale trees and forests to acquire more land for various agricultural, industrial, and urban purposes. It leads to the permanent destruction of forests and has significant environmental, social, and economic impacts. Trees are important for survival as they provide oxygen and several raw materials and maintain temperature. Their removal has become one of the leading environmental issues in recent times.
Large-scale removal of trees and forests for industrial and agricultural purposes has led to disruption of the environment and caused a drastic change in the temperature of Earth. Deforestation has also caused the loss of wildlife as forests provide shelter to a large number of animals and birds, making it one of the global environmental issues.
Overpopulation
Overpopulation is a situation in which the population becomes larger than the holding capacity of the environment. In the past few decades, overpopulation has become an issue of the world. Overpopulation puts a lot of pressure on the environment and has led to most of environmental issues such as climate change, deforestation, and global warming.
Solutions to Environmental Issues
