Scope and Importance of Environmental Studies

The word “environment” comes in the French word Environner that means to encircle or surround. The term “environment” refers to multiple variables that encompass humans as well as living creatures. Environmental studies examine the interrelations between organisms the environment and all variables that impact the life on earth, such as the weather, food chains and the water cycle and so on. It is a fundamental science that studies our earth and its everyday activities which is why this field of study is essential for all.

Environmental studies are a broad field.

Environmental studies is a discipline that has multiple and multilevel responsibilities. It is important and essential not just for children, but also for all. The study’s scope is summarized in the following manner:

  • The study helps people of different renewable and nonrenewable resources in the region. The endowment or potential patterns of utilization as well as the amount of resources that are available for future use in the condition of a nation are examined in the research.
  • It provides information about ecological systems as well as the relationship between cause and effect.
  • It gives essential information on biodiversity, as well as the possible threats to species of animals, plants and microorganisms that live in the environment.
  • The research helps identify the causes and effects of natural and major generated catastrophes (flood or earthquake, landslide, landslide or cyclones.,) and pollutions and ways to reduce the impact.
  • It lets one evaluate various options to address environmental concerns before deciding on the best course of action.
  • The study helps environmentally educated citizens (by being aware of the environmental laws as well as the rules, rights and laws, etc.) to make the right decision-making to protect and improve the condition of the planet.
  • The study exposes the issues of overpopulation and health, hygiene, and so on. and the importance of the technology, science and the arts in removing or minimizing social evils.
  • The research aims to determine and develop indigenous, appropriate environmentally friendly skills and techniques for various environmental issues.
  • It educates the citizens on how to make sustainable use of resources since the resources we inherit from our ancestors and passed on to the younger generation, and they do not diminish in quality.

The study helps to translate the application of knowledge in practice and the numerous uses for the environment.

The importance of studying the environment

Environmental studies are based on an in-depth understanding of different environmental systems. Its aim is to make citizens able to conduct research and find the practical solutions to present environmental issues. Citizens are able to examine the environmental variables like the terrestrial, aquatic, and atmospheric systems as well as their relationships with the biosphere and the anthrosphere.

Importance

  • The world population is growing at alarming rates, particularly in the developing world.
  • The amount of natural resources available to the earth are only a small portion of the earth’s resources.
  • The techniques and methods of extracting natural resources are being developed.
  • The resources are being over-exploited,, and no one has the way of transferring the wealth to future generations.
  • Unplanned use of natural resources leads to pollution of all kinds as well as at every level.
  • The environmental degradation and pollution can seriously impact the well-being of all living creatures on earth , including human.
  • The citizens should accept jointly the accountability for the degradation of the environment and start taking appropriate steps to increase the size of the earth.
  • Education and training are essential to protect biodiversity of the species and prevent their extinct.
  • The urban zone, when combined with the industrial sector, is among the major pollutant sources.
  • The area and number of extinct species under protected areas must be increased to ensure that the wild animals are protected at the very least in these places.
  • The study allows individuals to appreciate the complexities of the natural environment and the necessity for them to adopt to appropriate actions and seek sustainable development that is compatible with the surroundings.
  • The study encourages students to be involved in community activities and take part in a variety of initiatives related to the environment and management.
  • It’s a good moment to change the direction of educational systems and curricula to meet these demands.

Environmental studies are an approach that is multidisciplinary to research interactions between humans and the natural environment. It blends various approaches from the humanities, social sciences including biological sciences, physical and social sciences, and uses these methods to examine environmental issues.

Environmental study is an essential instrument to bring about the modifications in knowledge of values, behaviours, and habits required to ensure sustainability and stability in and across nations.

Environmental studies tackles each aspect that affects the organism. It is fundamentally an inter-disciplinary approach that allows for a greater understanding of the natural world as well as human impact on its quality. It is a applied science, which is seeking practical solutions to make our civilization sustainable and able to rely on Earth’s scarce resources. Its elements include

  • Biology
  • Geology
  • Chemistry
  • Physics
  • Engineering
  • Sociology
  • Health
  • Anthropology

  • Philosophy

Environmental issues that are major

Nature and man have always been in harmony for a long time and when man’s needs were in line with nature it was a breeze. Unfortunately, man’s quest to have unlimited pleasure and happiness has led him to the use of nature’s resources and in a manner that has diminished nature’s self-stabilization capacity. The incessant exploiting of nature over the course of many centuries has caused a myriad of environmental issues. Man’s insatiable need for resources and desire to control nature has put him in a collision with the environment. The demands of a rapidly growing technological world place a huge strain on the balance with the natural world. Some of the major environmental problems that threaten humanity are global warming and pesticides, water pollution hazardous waste, biomedical wastes, e waste and the loss of biodiversity

India is currently one of the ten first industrialized nations in the world. We are today blessed with a strong industrial infrastructure, especially in the key industries such as fertilizers, chemicals, metals and petroleum, food, etc. 

What have we learned from these? Pesticides, plastics, detergents dyes, paints and food additives, etc. Because of the advancement in the field of atomic energy, there has also increasing levels of biological radioactivity. Alongside this, there is numerous industrial effluents and emission sources, including poisonous gases that are found in the air. Mining activities are also contributing to the issue, especially in the form of solid waste.

Man’s activities had an negative consequences for all kinds of living organisms within the biosphere. The earth and the atmosphere (air land, water,) which provides life to the planet is known as the Biosphere. Because of the lack of an environment that is able to control pollution it has led to an immense backlog of liquid, gaseous and solid pollutants in our nation. The solid wastes that cause pollution are hazardous waste as well as pesticides, medical waste and so on. They are now the most significant environmental problems, in addition to the impact of automobiles on climate change, pollution from vehicles and pollution by pesticides, water pollution, and biodiversity loss across the globe.

Pollution from vehicles and industrial sources

The most infamous culprits for urban pollution are industrial and vehicular pollution. Since 1975, the Indian economy has expanded 2.5 times, while the industrial pollution load has increased 3.47 times and the traffic pollution burden has increased 7.5 times. In Delhi as an example, 70% of the air pollution is due to vehicle pollution. Because of the three million vehicles that travel its roads. Industries make up 17% of the pollution. The pollution emitted by vehicles may cause inflammation on the respiratory system, may be harmful or carcinogenic based on the fuel type. In India automobiles primarily use petrol or diesel.

Automobiles emit air pollutants.

Climate Change

The increasing levels of greenhouse gas (GHGs) that are anthropogenic in origin in the atmosphere, such as carbon dioxide (CO2) methane (CH4) and the nitrous oxide (N2O) have increased from the 19th century to the present. Based on the Third Assessment Report (TAR) of the Intergovernmental Panel on Climate Change due to the rise in atmospheric greenhouse gasses (for e.g. CO2 up by 29 percent and CH4 by 150 per cent, and N2O by 15 percent) over the past century, median temperature of the surface has increased by 0.4-0.8degC worldwide. The rainfall has been changing spatially and the frequency and intensity of extreme events have increased. The sea level has increased at an average annual increase of between 1-2 millimeters during the time. 

The constant increase in the amount of GHG in the atmosphere could cause climate changes that result in massive changes to ecosystems that could cause devastating disruptions to livelihoods as well as life-styles, economic activity as well as human health. According to the United Nations Framework Convention on Climate Change stipulates that all parties to safeguard the climate system according of their “common but distinct obligations’ and capacities. 

In 1990, the advanced the world (Australia, Canada, USA, Europe, former USSR and Japan) generated 65 percent of world’s total GHG emissions. However, this was reduced to 54 percent in percent in 2000, mostly due to the increase of Chinese emissions. It is estimated that the South Asian region, including three-fourths of the emission portion of India and China, accounted for just three percent of worldwide GHG emission in the year 1990. Moreover, the percentage of emissions originating of South Asia has grown merely by 4% since 2000.

Pollution of water

India includes 12 rivers that have an area of catchment totalling 252.8 million hectares. The Indian homes generate approximately 75 percent of the waste and the wastewater treatment facilities are insufficient for most cities, and nearly non-existent within rural India. As per the Central pollution Control Board, of the 8,432 major medium and large industries across the country, only 4,989 implemented proper methods to treat wastewater prior to discharge. Of the more than two million small-scale industrial units, many of which, like tanneries, have been found to be extremely polluting, only few have treatment facilities at all and their wastewater that is not treated will always find its ways into water systems in the country.

  • Tanks polluted
  • Pollution from the ocean
  • Industrial pollution

Poisoned by Pesticides

Pesticide poisoning is a problem that is a problem that affects 68,000 farmers and their workers each day. Each year approximately 25 million people suffer from poisoning caused by pesticides around the world. Farmworkers and workers in the agricultural sector are exposed pesticides in direct contact when mixing or spraying pesticides, particularly in countries that are developing, such as Asia. Each year, around 3 million people get poisoned in the world, and more than 200,000 are killed due to using pesticides.

Beyond the reported cases of poisoning by pesticides ever more alarming are the long-term consequences, such as cancers, adverse reactions-not just on particular organs or systems, but also on the endocrine system, which includes the reduction of male sperm count and undecided test results and an increase in incidence from breast cancer. People and communities are constantly exposed to pesticides via contamination of air, soil and water. The long-term effects of pesticides are particularly alarming when fresh studies show that certain pesticides are linked to cancer, decreased fertility and disruption to the endocrine system, as well as the suppression of immune systems.

Pesticides are a major cause of concern.

The struggle of the common worker in the plantation industry of Malaysia against the repercussions of pesticides, such as Parquet, as well as what they are entitled to as employees.

The story of ex-International Rice Research Institute (IRRI) workers in the Philippines poisoned by pesticides in the IRRI test fields, and then unjustly healed by IRRI. There are also details of the fisher community of Kamukhaan in Philips which were affected by poisoning and the destruction of their habitat by Pesticides used in the nearby banana plantation.

The people living at Kasar code, Kerala who were poisoned by Endosulfan which was air sprays in the Plantation Corporation in Kerala, India.

Community of farmers and agricultural workers located in Warangal, Andhra Pradesh, which have been poisoned by pesticides in spraying. Warangal is well-known for its high number of suicides by cotton farmers One of the major causes of the farmers’ take their own lives is the resistance created by pesticides against pests.

Pesticides Action Network Asia and the Pacific (PANAD) was the first to began a campaign called ‘No Pesticide Use Day in 1998 to oppose the use and manufacture of pesticides across the world. This day is observed in honor of the thousands who died, as well as the thousands of people who suffer and are dying in the aftermath of Bhopal in 1984. Bhopal Disaster. Bhopal’s tragedy Bhopal is a tragic and poignant reminder of the dangers of the toxicity of pesticides and chemicals The victims continue to be affected to this day.

Pescticides In Soft Drinks

Soft drinks are water-based, non-alcoholic drinks with flavors that can be carbonated, acidulated, and sweetened. Certain carbonated soft drinks contain caffeine, mainly the cola drinks with a brown color. Two global giants PepsiCo as well as Coca-Cola dominate the market for soft drinks in India.

Coco cola brands include Thumps Up, Limca, sprite, Minute Maid, and Gold Spot from Parle Beverages and soft drink brands Crush, Canada Dry and Sport Cola from Cadbury

Pepsico brands – Pepsi-Cola Brands ,Frito-Lay Brands ,Tropicana Brands ,Quaker Brands ,Gatorade Brands

Sample Analysis

A report from a laboratory conducted by CSE in 2003 revealed amazing facts about the severity of pesticides present in soft drinks that are sold in India. CSE discovered excessive concentrations of harmful pesticides as well as insecticides high enough to cause cancer as well as destruction of reproductive and nervous systems birth defects, as well as severe impairment of our immune system. Leading market players Coca-Cola and Pepsi were found to have similar levels of residues from pesticides. The same time, CSE also examined two soft drink brands that are sold in the US to determine whether they had pesticides in them. They did not. This just shows companies were adhering to two different standard.

In the list of pesticides that have been found in 18 cities across India, Kolkata is on the top, while Guwahati is at the bottom of the list. Kolkata has a pesticide content in cold beverages of around 51.7 ppb. Pesticides can cause irreparable damage to human bodies.

It has been demonstrated repeatedly that pesticides can be employed to kill bacteria in bathrooms. The acidic nature of these drinks can be dangerous to human health.

Hazardous waste could be solid, liquid, or gas. All have one thing in common: they are risky and be a significant risk for human health and the environment if not properly managed. In India there is a significant amount of hazardous waste can be to about 6 to 7 million tonnes per year and could vary according to the nature and volume of hazardous waste produced in India. The main hazardous waste generated in India includes pharmaceuticals, petrochemicals pesticides, paints fertilizers, dyes, chlor-alkali and many other industries.

Release of hazardous wastes from industrial facilities

A lack of preventative approach to managing waste has led to the creation of increasingly hazardous wastes, and unfortunately, the control of dangerous waste is now an enormous issue within India and no extra consideration is given to the management of these wastes. The implementation of the ban in the first place is incredibly insensitive which is why hazardous waste is leaking into our shores regularly. Apart from producing hazardous wastes for themselves, India invites import to this waste for the sake of recycling and reuse even though there is a lack of environmentally friendly technologies to recycle and reuse hazardous waste.

In the end, uncontrolled generations, poor handling disposal and storage in hazardous waste are among the major causes of the health and environmental adverse effects. It is imperative to review the current method of pollution control as well as end-of-pipe strategies and concentrate on prevention of pollution and waste minimization, as well as more sustainable production methods and reducing toxics.

Dumping of Tannery Sludge:

Biomedical Waste

Biomedical waste is comprised of organic waste and non-organic ones that are generated in hospitals. In the average, an average hospital bed, it produces 1 kilos of waste each day. Out of that 10% is infectious, while 5 percent is dangerous and the remainder is general waste. Everyday, our numerous hospitals and medical facilities pump out tons of waste. A WHO report shows the fact that Hepatitis – B virus can live during the spring season for eight days.

The syringe that is disposable and used for security could actually give an illusion of security. It could actually be a syringe used in the past that was that has been repackaged by the mafia who are involved in trafficking medical waste.

Unhealed and unmediated syringes at the municipal dump can return to hospitals and be administered to patients, who could become cross-infected.

The issue of medical waste has taken on enormous proportions and complicated dimensions. While health facilities attempt to provide better medicare service to citizens however, hospital waste disposal system is thwarting the efforts of these institutions. The regulations for managing this waste are in place. What is needed urgently is a training program for all health professionals and establishing a waste management procedures in hospitals.

Plastics comprise a significant portion of the medical waste. In India markets for medical waste has increased to US$2.350 millions (1979) to 4 millions (1986). Plastics used in the medical field are currently increasing at a pace of 6 percent annually. Although plastics can reduce the risk of transmitting infection in the hospital There are many issues that arise from its usage and removal.

Crackers are being cracked down

In the past, Diwali has turned into one of the biggest festivals for pollution due to crackers, noise and artificially colored sweets, as well as grave health hazards. On the day of Diwali, cities transform into gas chambers, which increases the gasses and toxic fumes like NO2, CO2, SO2 and suspended particles (SPM) and suspended particulate matter (SPM) that are inhaled. 

Children are the most affected. Women who are pregnant and suffer with respiratory ailments are the most affected. Additionally crackers are made by factories that violate safety regulations and use child labor. The children are employed for 16-18 hours a day in filthy, dirty, manufacturing facilities that are made-to-order and choked to death for Rs.10-15 daily. They deal with chemicals that can causes deadly disease of the kidneys, lungs eyelids, skin and lungs.

E Waste

  • Computers are discarded each two-to four years, on average.
  • Cell phones last a period that is less than two years in developed countries.
  • Each computer screen has around 20% lead per weight.
  • A mobile phone contains 19 percent copper and eight percent iron.
  • Informal name for electronic items that are nearing the at the end in their “useful life”.
  • Large appliances in the household – Refrigerators Computers, air conditioners and Stereo systems, mobile phones.
  • Its volume grows by 3 to 5 percent per year.
  • The most significant pollutants are heavy metals, such as Hg Pb, Cd, Cr (VI) and flame retardants – Polybrominated Biphenyls (PBB) as well as polybrominated diphenylethers (PBDEs).

International Scenario

  • 20-50 MT/year of e-waste are produced around the globe.
  • USA contributes between 1% and 3% of the total municipal waste production.
  • EU 5 – 7 millions tonnes per year roughly 14 to 15 kg per person and is predicted to grow at an average of 3%-5 percent per year.
  • In the advanced countries, it is 1percent of the total solid waste production and is projected to rise to 2% by the year 2010.
  • The magnitude of the problem in India
  • India 1.46,000 in 2011 4.7 lakh tonnes in the year 2011.
  • India’s e-waste production is increasing at a rate of 15% and is projected to surpass 800,000 tonnes by 2012.
  • More than 60 per cent of total e-waste generated in India.
  • The top cities (70 70 %) The top cities (70%) are Mumbai, Delhi, Bangalore, Chennai, Kolkata, Ahmedabad, Hyderabad, Pune, Surat and Nagpur.
  • A total of 50,000 MT per year is illegally imported.

Loss of Biodiversity

The constant loss of biodiversity due to overexploitation and habitat destruction, deforestation, land pollution and deforestation is a major danger to the very existence of humanity. It is estimated that if this pattern of loss of biodiversity continues, approximately 1/4th of the species on earth could be extinct by 2050 date. The rate of loss that is in the region of one species a year for the past 600 million years is now thought to be hundreds of species per day. Therefore, conserving biodiversity is one of the biggest environmental concerns. The task is for countries and government agencies, as well as organizations and individuals to preserve and improve biodiversity and still meet the requirements to have natural resources.

We are at an important change in human history which means that for the very first times, we have the tools in the form of motivation, knowledge, and motivation to safeguard our environment and create a sustainable future for our children. Up until recently, we did not have these options or enough evidence that could inspire people to make a change in their lifestyles and make a commitment to environmental protection. Today, the need is evident to almost everyone. It’s unfortunate that this may be the last chance to act before our environmental problems become irreparable.
