WHAT IS ENVIROMENT?

Environment is the total sum of what is around something or someone . It includes living things and natural forces .The environment of living things provides conditions for development and growth, as well as of danger and damage. Living things do not simply exist in their environment. They constantly interact with it. Organisms change in response to conditions in their environment.

The word environment is used to talk about many things. People in different fields of knowledge (like history, geography or biology) use the word differently. An electromagnetic environment is the various radio waves that equipment such as radio and radar can meet. Galactic environment refers to conditions between the stars.

In psychology and medicine a person's environment is the people, physical things, places, and events that the person lives with. The environment affects the growth and development of the person. It affects the person's behavior.

Types of environment

The five types of environment are : Aquatic, forest, desert, grassland , and tundra environment or biomes . Each of these can be found in many areas around the world and contribute to the world’s ecosystem .

AQUATIC ENVIRONMENT: Aquatic environments are found all over the world. Roughly 75 percentage of the Earth is covered by water, and all of this water is part of an aquatic environment . The aquatic biome is further divided into saltwater oceans and freshwater environments , such as rivers and lakes

AQUATIC ENVIRONMENT:

Aquatic Environment

Fresh water

Rivers

Lakes

Saltwater oceans

FOREST ENVIRONMENT: Forests biomes are characterized by large trees and vegetation .They can be found in cold and warm temperatures around the world .These environments are important to the Earth because they release oxygen into the atmosphere and capture excess carbon dioxide .

FOREST ENVIRONMEN

T

DESERTAL ENVIRONMENT: Deserts are any type of environment that receives less than 10 inches of precipitation each year . They can be very hot and sandy or very cold and icy.

DESERTAL ENVIRONMENT

GRASSLAND ENVIRONMENT Grasslands are large biomes characterized by huge open areas that receive between 10 to 30 inches of precipitation per year. These areas are covered mostly by grass and have few trees and other types of vegetation .They are home to a wide variety of animals that use the grass for food.

GRASSLAND ENVIRONMENT

TUNDRA ENVIRONMENT: Tundra is the coldest biome of all of the different environments. Tundra’s have long, cold winters and very short summers .

TUNDRA ENVIRONMENT

WHAT IS NATURAL ENVIRONMENT? The natural environment encompasses all living and non-living things occurring naturally on Earth or some region thereof. It is an environment that encompasses the interaction of all living species. Climate, weather, and natural resources that affect human survival and economic activity.

The concept of the natural environment can be distinguished by components: Complete ecological units that function as natural systems without massive civilized human intervention, including all vegetation, microorganisms, soil, rocks, atmosphere, and natural phenomena that occur within their boundaries Universal natural resources and physical phenomena that lack clear-cut boundaries, such as air, water, and climate, as well as energy, radiation, electric charge, and magnetism, not originating from civilized human activity

NATURAL ENVIRONMENT

Environmental pollution can

be defined as any undesirable change in physical, chemical or

biological characteristics of any components of the

environment i.e air , water ,soil which can cause harmful effects on various forms of life or property.

There are several types of pollution, and while they may come from different

sources and have different consequences,

understanding the basics about pollution can help

environmentally conscious individuals minimize their

contribution to these dangers. In total, there are nine recognized sources of

pollution in the modern world.

Pollution

Air Pollution

Air pollution is the introduction of particulates, biological molecules, or other harmful gases into Earth's atmosphere, causing disease, death to humans, damage to other living organisms such as food crops, or the natural or built environment. Air pollution may come from anthropogenic or natural sources.

CAUSES OF AIR POLLUTION : There are various locations, activities or factors which are responsible for releasing pollutants into the atmosphere. These sources can be classified into two major categories.

Anthropogenic (man-made) sources:These are mostly related to the burning of multiple types of fuel. Stationary sources include smoke stacks of power plants, manufacturing facilities (factories) and waste incinerators, as well as furnaces and other types of fuel-burning heating devices. In developing and poor countries, traditional biomass burning is the major source of air pollutants; traditional biomass includes wood, crop waste and dung.

Mobile sources include motor vehicles, marine vessels, and aircraft. Controlled burn practices in agriculture and forest management. Controlled or prescribed burning is a technique sometimes used in forest management, farming, prairie restoration or greenhouse gas abatement. Fire is a natural part of both forest and grassland ecology and controlled fire can be a tool for foresters.

WATER POLLUTION

Water pollution is the contamination of water bodies (e.g. lakes, rivers, oceans, aquifers and groundwater). This form of environmental degradation occurs when pollutants are directly or indirectly discharged into water bodies without adequate treatment to remove harmful compounds.

Water pollution is a major global problem which requires ongoing evaluation and revision of water resource policy at all levels (international down to individual aquifers and wells). It has been suggested that water pollution is the leading worldwide cause of deaths and diseases, and that it accounts for the deaths of more than 14,000 people daily.

The specific contaminants leading to pollution in water include a wide spectrum of chemicals, pathogens, and physical changes such as elevated temperature and discoloration. While many of the chemicals and substances that are regulated may be naturally occurring (calcium, sodium, iron, manganese, etc.) the concentration is often the key in determining what is a natural component of water and what is a contaminant.

Oxygen depleting substances may be natural materials such as plant matter (e.g. leaves and grass) as well as man-made chemicals. Other natural and anthropogenic substances may cause turbidity (cloudiness) which blocks light and disrupts plant growth, and clogs the gills of some fish species. Many of the chemical substances are toxic. Pathogens can produce waterborne diseases in either human or animal hosts

Water pollution

SHOULD THE WATER BE CLEAN AND PURE OR SHOULD IT BE LIKE THIS….??

Noise pollution or noise disturbance is the disturbing or excessive noise that may harm the activity or balance of human or animal life. The source of most outdoor noise worldwide is mainly caused by machines and transportation systems, motor vehicles, aircraft, and trains. Outdoor noise is summarized by the word environmental noise.

High noise levels can contribute to cardiovascular effects in humans, a rise in blood pressure, causing head-ache, and an increase in stress , and an increased incidence of coronary artery disease. In animals, noise can increase the risk of death by altering predator or prey detection and avoidance, interfere with reproduction, and contribute to permanent hearing loss.

HEALTH EFFECTS:

HEARING LOSS

There are six main reasons for noise pollution: 1.Industrialization 2.Poor urban planning 3.Social events 4.Transportation 5.Construction 6.House hold chores This form of pollution may seem harmless, it in fact has far reaching consequences. The adverse effects on the health of the environment are quite severe.

CAUSES OF NOISE POLLUTION

Land Pollution means means degradation or destruction of earth’s surface and soil, directly or indirectly as a result of human activities. Anthropogenic activities are conducted citing development, and the same affects the land drastically, we witness land pollution; by drastic we are referring to any activity that lessens the quality and/or productivity of the land .

CAUSES OF LAND POLLUTION

There are eight main causes for land pollution: 1.Deforestation and soil erosion. 2.Agricultural activities 3.Mining activities 4.Overcrowded landfills 5.Industrialization 6.Construction activities 7.Nuclear waste 8.Sewage treatment

Some effects of land pollution: 1.Soil pollution 2.Change in climate patterns. 3.Environmental impact 4.Effects on human health 5.Cause air pollution 6.Distraction for tourists 7.Effect on wildlife

SOME SOLUTIONS : 1. Make people aware about the concept of Reduce, Recycle and Reuse.2. Reduce the use of pesticides and fertilizers in agricultural activities.3. Avoid buying packages items as they will lead to garbage and end up in landfill site.4. Ensure that you do not litter on the ground and do proper disposal of garbage.5. Buy biodegradable products.

Solutions For Land Pollution

World Environment Day (WED) is celebrated every year on 5 June to raise global awareness to take positive environmental action to protect nature and the planet Earth. It is run by the United Nations Environment Programme .

It was established by the United Nations General Assembly in 1972 on the day that United Nations Conference on the Human Environment began.

Earth Anthem" by poet-diplomat Abhay K was launched in June 2013 on the occasion of the World Environment Day by Kapil Sibal and Shashi Tharoor.

“Our cosmic oasis, cosmic blue pearlthe most beautiful planet in the universeall the continents and the oceans of the worldunited we stand as flora and faunaunited we stand as species of one earthblack, brown, white, different colourswe are humans, the earth is our home.

Our cosmic oasis, cosmic blue pearlthe most beautiful planet in the universeall the people and the nations of the worldall for one and one for allunited we unfurl the blue marble flagblack, brown, white, different colourswe are humans, the earth is our home.”
