Environmental degradation is a result of socio-economical, technological and institutional activities. Degradation occurs when Earth's natural resources are depleted. These resources which are affected include:
Water
Air
Soil
The degradation also impacts our:
Wildlife
Plants
Animals
Micro-organisms
The problems resulting from environmental change and its degradation, pose new challenges for traditional public health science. It is an accepted fact that, environmental degradation is contributing to human health threats worldwide. We may have several questions in our mind.
Land pollution is the deterioration (destruction) of the earth’s land surfaces, often directly or indirectly as a result of man’s activities and their misuse of land resources.

Altered Terrain: Colonial Encroachment and Environmental Changes in Cachar, A...PriyankaKilaniya
The beginning of colonial policy in the area was signaled by the British annexation of the Cachar district in southern Assam in 1832. The region became an alluring investment opportunity for Europeans after British rule over Cachar, especially after the accidental discovery of wild tea in 1855. Within this historical context, this study explores three major stages that characterize the evolution of nature. First, it examines the distribution and growth of tea plantations, examining their size and rate of expansion. The second aspect of the study examines the consequences of land concessions, which led to the initial loss of native forests. Finally, the study investigates the increased strain on forests caused by migrant workers' demands. It also highlights the crucial role that the Forest Department plays in protecting these natural habitats from the invasion of tea planters. This study aims to analyze the intricate relationship between colonialism and the altered landscape of Cachar, Assam, by means of a thorough investigation, shedding light on the environmental, economic, and societal aspects of this historical transformation.
UNDERSTANDING WHAT GREEN WASHING IS!.pdfJulietMogola
Many companies today use green washing to lure the public into thinking they are conserving the environment but in real sense they are doing more harm. There have been such several cases from very big companies here in Kenya and also globally. This ranges from various sectors from manufacturing and goes to consumer products. Educating people on greenwashing will enable people to make better choices based on their analysis and not on what they see on marketing sites.
"Understanding the Carbon Cycle: Processes, Human Impacts, and Strategies for...MMariSelvam4
The carbon cycle is a critical component of Earth's environmental system, governing the movement and transformation of carbon through various reservoirs, including the atmosphere, oceans, soil, and living organisms. This complex cycle involves several key processes such as photosynthesis, respiration, decomposition, and carbon sequestration, each contributing to the regulation of carbon levels on the planet.
Human activities, particularly fossil fuel combustion and deforestation, have significantly altered the natural carbon cycle, leading to increased atmospheric carbon dioxide concentrations and driving climate change. Understanding the intricacies of the carbon cycle is essential for assessing the impacts of these changes and developing effective mitigation strategies.
By studying the carbon cycle, scientists can identify carbon sources and sinks, measure carbon fluxes, and predict future trends. This knowledge is crucial for crafting policies aimed at reducing carbon emissions, enhancing carbon storage, and promoting sustainable practices. The carbon cycle's interplay with climate systems, ecosystems, and human activities underscores its importance in maintaining a stable and healthy planet.
In-depth exploration of the carbon cycle reveals the delicate balance required to sustain life and the urgent need to address anthropogenic influences. Through research, education, and policy, we can work towards restoring equilibrium in the carbon cycle and ensuring a sustainable future for generations to come.
Climate Change All over the World .pptxsairaanwer024
Climate change refers to significant and lasting changes in the average weather patterns over periods ranging from decades to millions of years. It encompasses both global warming driven by human emissions of greenhouse gases and the resulting large-scale shifts in weather patterns. While climate change is a natural phenomenon, human activities, particularly since the Industrial Revolution, have accelerated its pace and intensity

Structure andcomposition of soil
• The soil is the superficial
layer of Earth’s solid crust and also part of the
biosphere.
• Soil consists of solid particles packed together
in a porous structure.
• In the pores air, vapor, water or smaller
particles may appear, and this is also where the
special microflora of the soil resides.
5. MECHANICAL COMPOSITION AND STRUCTURE OF SOIL
The composition of the soil consists of four major components: –
mineral (50–60 % of total); – organic matter (10 %); – air (15–25
%); – water (25–35 %).
SOIL CLASSIFICATION
Unified international classification of soils has not yet been
developed. Distinguish the following types of soil:
– stony;
– sandy (more than 80 % sand);
– sandy-loamy;
– clay (60 % clay);
– loam

Definition of soil hygiene
• Soil hygiene focuses on
natural
and anthropogenic pollutants
(from water and through air
precipitation, chemicals, waste,
sewage) present in soil,
affecting
human health.
9. 4/8/2017 9
Most important soil contaminants
• Inorganic pollutants
1. Nitrates and nitrites
2. Heavy metals
3. Arsenic
• Organic pollutants
6. Pesticides
7. PAH
8. Soil-borne pathogens
• Radioactive pollution
10. 1. Deforestation : It is the removal of a forest or stand of trees
where the land is thereafter converted to a non-forest use .
Deforestation also loosens the soil and hence leads to soil
erosion , Land that is once converted into a dry or barren
land, can never be made fertile again. Hence deforestation
is one of the major reason to soil pollution.
Deforestation

11. 2. Agricultural activities: With growing human population, demand for
food has increased considerably. Farmers often use highly toxic
fertilizers and pesticides to get rid off insects, fungi and bacteria from
their crops. However with the overuse of these chemicals, they result
in contamination and poisoning of soil.
Pesticides being sprayed

12. 3. Unskilled irrigation: Water logging may occur when the
drainage system of the agricultural field is not maintained
scientifically. Water logging closes the passage of air to the
soil, stops the growth of soil organisms and makes the soil
barren.
Water logging

13. 4. Overcrowded landfills: Each household produces tones of
garbage each year. Garbage like aluminum, plastic, paper,
cloth, wood is collected and sent to the
local recycling unit. Items that can not be recycled become
a part of the landfills and hence pollute the soil.
Overcrowded
landfills

14. 5. Mining Activities : Mining is also a source of land pollution. Huge
holes are dug in mining, and these holes form can pose a hazard to
us as they form deep mining pools. Metals like cadmium and lead
will be deposited, which are toxic, contaminating the soil. This will
leave the mining land barren and unable to use again .
Mining activities

15. 6. Shifting cultivation: In it, the forest is burnt to use the land for
cultivation, until the soil loses it’s fertility. Once the land
becomes inadequate for crop production, it is left barren and
hence it leads to soil erosion. This method is mostly used by
tribes.

are very hazardous and can lead to the loss of ecosystems.
When land is polluted, it directly or indirectly affects
the climate patterns.
3. Contamination of underground and surface drinking water.

19. 4. Environmental Impact: When deforestation is committed, the tree
cover is compromised on. This leads to a steep imbalance in the rain
cycle. A disturbed rain cycle affects a lot of factors. To begin with, the
green cover is reduced. Trees and plants help balance the
atmosphere, without them we are subjected to various concerns
like Global warming, the green house effect, irregular rainfall and
flash floods among other imbalances.

toxic chemicals and pesticides lead to problem of skin
cancer and human respiratory system. The toxic chemicals
can reach our body through foods and vegetables that we
eat as they are grown in polluted soil.

growing due to increase in waste and are later burned
which leads to air pollution. They become home for
rodents, mice etc which in turn transmit diseases.

23. 8. Effect on wildlife: The animal kingdom has suffered mostly in the past
decades. They face a serious threat with regards to loss of habitat and
natural environment. The constant human activity on land, is leaving
it polluted; forcing these species to move further away and adapt to
new regions or die trying to adjust. Several species are pushed to the
verge of extinction, due to no homeland.
Animals on verge of extinctionAnimals are forced to leave their home and are
mostly killed by vehicles

24. 9. Global Warming : soil pollution also leads to global
warming as the one of the main cause of soil erosion is
deforestation and due that there is a imbalance in the ratio
of oxygen and carbon dioxide . Hence there is a rise in
temperature leading to Global Warming.

25. 10. Biomagnification : The discharge of
chemicals on land, makes it dangerous for the
ecosystem too. These chemicals are
consumed by the animals and plants and
thereby make their way in the ecosystem. This
process is called bio magnification and is a
serious threat to the ecology.
