Environmental Science

ENVIRONMENTAL SCIENCE

Environmental science is a branch of science which has interdisciplinary fields like physical, biological and information science including plant science, physics, biology, ecology, geology, social science, zoology, atmospheric science and physical geography to the study of the Environment and the solution of the Environmental problems.

Some Important components of the Environment:

1.     Atmospheric Sciences:

It deals with the Earth’s atmosphere that focuses on interrelation to the other components.  Atmospheric science can also include greenhouse gas phenomena, meteorology, and atmospheric dispersion modeling of airborne contaminants, sound propagation phenomena related to noise pollution, and even light pollution. For Example

Global warming, infrared radiation transmission, inventory of atmospheric chemicals and their reactions, carbon dioxide fluxes.

2.     Geosciences:

It focuses on evolution earth’s crust like environmental soil science, environmental geology and volcanic phenomena. In some types of systems, it can also include oceanography and hydrology. For example

Soil erosion, It is the main disadvantage of the environment. It is one of the problems refers to the wearing a way of fields topsoil by the natural physical forces by the water.

3.     Ecology:

It is the study of inter-reactions between organisms and their environment. It tries to study a relation between the population of organisms and some physical characteristics of their environment. Such as concentration of a chemical or investigate the interaction between two population organisms through competitive relationship.

For example analysis of an ecological system which has been impacting by the one or more stressors might include different types of environmental science fields.

Organizations of Environmental Sciences:

These are the major international organizations in the world.

1.     Earth System Governance Project(ESGP):

It is started in 2010 by the developing countries which are most affected by environment and climate change. These countries are located around the Pacific Ocean and the Caribbean and some around Africa. But lack of interest of mentioned nations didn’t come to effect into the project.   

2.     Global Environmental Facility(GEF):

It was established I 1991 as a partnership of among 183 nations, international institutes, civic organizations, private businesses. This organization works on projects concerning climate change, international water, biodiversity, land degradation, and the ozone layer. Currently, it is the largest funder of these types of projects in this world. Together, these funds have contributed to 3,690 projects in 165 countries.

3.     Intergovernmental Panel on Climate Change(IPCC):

IPCC works in UN as a scientific and intergovernmental organization. It was established in 1988 by the world meteorological organization. It's based to offer the world and biased, scientific assessment and climate change and its effects.

4.     International Union of Conservation Nature(IUCN):

It was established in 1948 and is comprised of 1,200 governmental and non-governmental members. Its promotion is to promote sustainable natural resources and nature conservation of the natural resources around the globe. It also deals with issues such as gender equality, poverty, and sustainable business practices in order to achieve its objective.

5.     World Nature Organization (WNO):

Planning for world nature organization was started in 2010 by the countries which were developing at that time affected by climate change. It works on climate situations and climate-related problems worldwide.

Major Problems of Environment science:

These are the major environmental problems in the world.

1.     Climate change

2.     Deforestation

3.     Waste Disposal

4.     Loss of Biodiversity

5.     Pollution

1.     Climate change:

Climate change is a change that refers to the statistical distribution of weather patterns when the weather remains that change for a long period of time sometimes it would be decades to million years. It changes in average weather conditions or within the longer term average conditions. Climate change has become a problem to the Environment that it can be led to global warming.

2.     Deforestation:

In the world greenhouse, gas emission doesn't-come from factories and cars at least 15 percent. They come from Deforestation. Environment organizations decided that by 2030 there will be only 10 percent of rainforest left; remaining forests will be cut for agriculture uses.

3.     Waste of disposal:

Waste is generating in the society is bigger and very fast. It is to put or throw waste in the trash but there is a long process to disable or decrease the waste in the large amount. It has also become a big environmental problem in the world. By the organizational statistics, there is every person is producing 4.6 percent of waste around the world.

4.     Pollution:

The most popular pollution problems in the environment are land, air, water, and sound pollution. Pollution has become a big problem that has to be solved only by the people and the government. These types of pollution like soil irrigation and water pollution have massive pollution situations in the world.

5.     Loss of Biodiversity:

Biodiversity is the variety of life in the world that too in a particular ecosystem is declining. Loss of biodiversity that is a major problem in society. The environment that has to cross many problems to set a natural environment in the world.
