Environmental Issues
Environmental issues are the harmful effects of human activities on the environment. These include pollution, over-population, waste disposal, climate change, global warming, greenhouse effect, etc.
Various environment protection programs are being practised at the individual, organizational and government levels with the aim of establishing a balance between man and environment.
Some of the current environmental issues that require urgent attention are:
Global Warming
Warming of the Earth's lower atmosphere (troposphere) because of increases in the concentrations of one or more greenhouse gases. It can result in irreversible climate change that can last for decades to thousands of years.
Ozone Layer Depletion
The ozone layer is a layer of concentrated ozone gas. It protects us from the sun’s harmful ultraviolet rays. This very important layer is being destroyed by CFCs (chlorofluorocarbons), which are used in industries and everyday life (e.g. aerosol cans).
The chlorine in these compounds destroys the ozone layer. The hole in the ozone layer leaves humans and wildlife exposed to the harmful UV rays resulting in several skin diseases including cancer.
Water Pollution
The introduction of harmful substances into rivers, oceans, lakes and ponds, which changes the physical, chemical or biological condition of the water is called water pollution. The polluted water lacks oxygen and therefore the organisms die.
Water is the main source of life and therefore it is our prime duty to prevent it from any kind of pollution.
Air Pollution
Air pollution is the result of emissions from the industries, automobiles, and increasing use of fossil fuels. The gaseous emissions have added to an increase in the temperature of the earth. Not only this, but it had also increased the risk of diseases among individuals.
Solid Waste Management
Solid-waste management is defined as the discipline associated with the generation, storage, collection, transfer and transport, processing, and disposal of solid waste in a manner that it does not have a harmful effect on the environment.
Forests are an abode to a large number of wild animals and plants. Destruction of forests has led to the elimination of a large number of plants and animal species affecting the biodiversity.
Overpopulation
The earth’s population is increasing drastically. It is estimated to be more than seven billion. The increasing population has led to a shortage of resources. If this continues, it will be very difficult to sustain such a huge population. The other environmental issues including pollution, waste management, deforestation, climate change and global warming are all associated with over-population.
Solutions to Environmental Issues
Following are some of the most common solutions to the environmental issue:
- Replace disposal items with reusable items.
- The use of paper should be avoided.
- Conserve water and electricity.
- Support environmental friendly practices.
- Recycle the waste to conserve natural resources.
Environmental issues are a warning of the upcoming disaster. If these issues are not controlled, there will soon be no life on earth.
