Importance of Environmental Studies: Learn the Scope, Career, Salary in 2023

importance of environmental studies

Environmental Studies has become an integral part of the curriculum for school students. Nations across the globe understand the importance of Environmental Studies. Since its origins, the blue-green planet has seen many changes. It took millions of years for life to originate on Earth in the form of tiny microbes. From then to today, Earth has been inhabited by more than 8.7 million species, including humans. We have played a major role in the changes the planet faces today. In the race to develop ourselves and provide all the amenities, we have altered the environment negatively. Hence, the need to have environmental experts is at its peak.

However, the need to understand the importance of EVS took a bit of a struggle. The campaign began in the US in the 1970s by Senator Gaylord Nelson and William K Reilly. You will be surprised to learn that there were no laws for factories to not throw toxic wastes in water or any act that could put a check on the pollution level. But it all changed because of the hard work of two men who knew the importance of maintaining a healthy environment. Since then, it took many more years for the world to understand the importance of Environmental Studies and having environmental engineers who can protect our future.

What is Environmental Science?

What is Environmental Science

Environmental Science is the in-depth study of the environment and nature. It is an interdisciplinary field that involves other subjects like Physics, Biology, Geography, Geology, Meteorology, Sociology and other cultural aspects. One can explore many correlated aspects while studying Environmental Science after 10+2. Generally, the importance of environmental education is not considered as lucrative as other mainstream options when it comes to a student’s career. 

But with time and the need for a sustainable future, the prominence of Environmental Studies has increased. These days students are exploring this field to build a concrete career path. A student can continue studying Ecology, Biology, Chemistry, Geology, Geography, Zoology, Botany and related fields and become an environmentalist. Many construction organisations hire Environmental Engineers to build eco-friendly green buildings. Town planners these days have to study topics on Environmental Science. The scope and importance of Environmental Science are omnipresent in almost all professional fields. 

Nations are taking into cognizance the importance of Environmental Science and building laws and acts in partnership with expert environmentalists. Environmental science will play a significant role with the way global warming is altering the face of the Earth. 

Importance of Environmental Science 

A student studies Environmental Science in the primary classes. It teaches students the importance of the environment around us and sensitises them towards protecting natural resources. After 10+2, students can take up the cause further while pursuing their studies in Environmental Science. Students who are set to appear for the CUET 2023 can select Environmental Studies as one of their domain subjects. The CUET syllabus for Environmental Studies covers topics like;

· Human Beings and Nature

  • Population and Conservation Ecology
  • Sustainable Development 
  • World Wide Fund for Nature 
  • Greenpeace
  • Population Dynamics
  • Threats to the Ecosystem
  • Increasing Human Consumption
  • Expanding Agriculture 
  • Conservation 
  • Pollution Monitoring 
  • International and National Air Quality Standards 
  • Water Testing 
  • Soil Testing 
  • Third World Development 
  • Urban Environmental Planning and Management 
  • Sustainable Agriculture 
  • Green Revolution 
  • Environmental and Natural Resource Economics 
  • International Relations and the Environment
  • Impact of International Politics, National Sovereignty and Interest
  • International Aid

Today, Environmental Science has become fundamentally important while planning for the future. These are just a few topics covered in the CUET syllabus and will be taught to students pursuing further studies in Environmental Sciences.

Scope of Environmental Science 

When you talk about Environmental Science and the scope of Environmental Science, then it is not just one subject. As mentioned earlier, Environmental Science combines various subjects. Even if you are not pursuing a B. Sc or Bachelor’s in Environmental Science, you can still be an environmentalist with other disciplinary specialisation. If you are a Marine Biologist, you can go for a certificate course or a diploma in Environmental Science. The other career fields that are related to Environmental Science and will help you in planning your career successfully are;

  • Water Resource Management
  • Soil Ecology
  • Wildlife & Forestry 
  • Environmental Education 
  • Marine Biology
  • Fire Sciences 
  • Wildlife Conservation
  • Biological Conservation 
  • Energy & Climate Change
  • Ecology
  • Town Planning 
  • Sustainable Energy 
  • Environmental Engineering 

Types of Environmental Studies 

When we say the word ‘environment’ we refer to many things that constitute our surroundings. The atmosphere, land, water, flora & fauna all combined are what we call ‘Our environment’. Hence, the study of the environment cannot be limited to any one aspect of it. The study of the environment is divided into 5 major areas. The different types of Environmental Studies are:

1. Environmental Chemistry

Our surroundings are full of chemicals around us. Environmental chemistry covers the chemical and biochemical processes on Earth. The focus is on human activities’ impact on modifying the molecular chemistry of air, water and soil. 

2. Geosciences

Now, Geography is a vast field. Many areas are covered here, including Geophysics, Geochemistry, Geology and more. Geosciences is related to studying the terrestrial environment, including volcanoes, minerals, magnetic fields, tectonic plates, glaciers, etc. 

3. Forestry and Agricultural Sciences

The depleting green cover of the planet has drastically impacted the sea level and air quality of the planet. The Forestry and Agricultural Science field has been helping manage, research, explore and invent sustainable ways for farming, agriculture, national parks, wetlands, and wildlife habitats. 

4. Atmospheric Science

The atmosphere of the Earth has various layers. Each layer has a different composition and is impacted differently by manmade factors. Atmospheric Science is studied by Climatologists, Meteorologists, Physicists, Scientists and other experts. 

5. Oceanography and Marine Sciences

More than 70% of the Earth is water; still, we could not protect our seas from the dangerous industrial revolution. The churning of oil and human waste thrown into the water has made the aquatic habitat toxic for marine life. Oceanography and Marine Sciences studies are an integral part of Environmental Science. The experts help in protecting marine life and building a sustainable future. 

How to Become an Environmental Scientist
