This document summarizes the exploitation of natural and energy resources. It discusses how resource extraction has increased since the 19th century to meet growing energy demands. About 80% of the world's energy comes from non-renewable fossil fuels. Exploitation of resources causes problems like depletion of fossil fuels, deforestation, greenhouse gas emissions, water pollution and soil erosion. A case study examines how Tamil Nadu's leather industry pollutes water sources and a potential solution of using seawater and waste heat from a nearby power plant is proposed. The document advocates reducing, recycling and reusing resources through sustainable management practices.

"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.

The objective of this work is to contribute to valorization de Nephelium lappaceum by the characterization of kinetics of drying of seeds of Nephelium lappaceum. The seeds were dehydrated until a constant mass respectively in a drying oven and a microwawe oven. The temperatures and the powers of drying are respectively: 50, 60 and 70°C and 140, 280 and 420 W. The results show that the curves of drying of seeds of Nephelium lappaceum do not present a phase of constant kinetics. The coefficients of diffusion vary between 2.09.10-8 to 2.98. 10-8m-2/s in the interval of 50°C at 70°C and between 4.83×10-07 at 9.04×10-07 m-8/s for the powers going of 140 W with 420 W the relation between Arrhenius and a value of energy of activation of 16.49 kJ. mol-1 expressed the effect of the temperature on effective diffusivity.
1. EXPLOITATION OF NATURAL
AND ENERGY SOURCE

2. INTRODUCTION:
• The exploitation of natural and energy resources started to emerge
in the 19th century as natural resource extraction developed.
• During the 20th century, energy consumption rapidly increased.
• Today, about 80% of the world’s energy consumption is sustained by
the extraction of fossil fuels, which consists of oil, coal and gas.
• Another non-renewable resource that is exploited by humans
are Sub soil minerals such as precious metals that are mainly used in
the production of industrial commodities.
3. NATURAL RESOURCES:
Natural resource are the resource available in the nature like air ,water
sunlight ,soil,minearls,forest wild life etc.,
natural resource are of two main types renewable and non renewable natural
resources
RENEWABLE ENERGY:
• Those resources which can be replenished in short period of time like
air, water ,sunlight, forest etc.,
NON-RENEWABLE ENERGY:
• Those resources which can not be replenished in the short period of
time like minerals (coal,petroleum,natural gas, metals etc.,)because
they take millions of years to be formed.
4. SOME OF THE PROBLEMS ARISING FROM THE
EXPLOITATION OF NATURAL AND ENERGY
RESOURCES:
1.Depletion of fossil fuels
2.Deforestation
3.Green house gas increase
4.Water pollution
5.Soil erosion
5. DEPLETION OF FOSSIL FUEL:
Industrial revolution increased energy
demands.
Consumption of fossil fuels increased.
Rate of fossil fuels consumption larger than
rate of formation of fossil fuels.
Depletion of fossil fuels reserve: problem for
future generation.
6. DEFORESTATION:
Trees are cut down.
Sold as fuel or timber.
Land is used for settlements,
cultivation, etc.
Construction of dams for irrigation
facility.
Resulting in damage to habitat,
biodiversity loss and aridity.
7. GREEN HOUSE GAS INCREASE
Industrial revolution increased carbon
dioxide emission rapidly.
Combustion of fossil fuels.
Combustion of wood.
Emissions from automobiles.
Resulting in global warming
8. WATER POLLUTION:
Industries are situated beside water
bodies.
Pollutants are discharged into water
bodies.
Water pollution occurs.
Affects aquatic plants and organisms.
Resulting in deathly effect to the whole
natural biological communities.
9. SOIL EROSION:
Soil erosion is occurs naturally.
Soil erosion increased by 10-40%.
Deforestation, Construction of roads,
urbanization, etc are main causes.
Resulting in land degradation,
sedimentations of aquatic ecosystems, etc.
10. CASE STUDY:
THE LEATHER INDUSTRY IN TAMIL NADU :
• Over the years the groundwater in the areas where the tanneries are
located, has become intolerably polluted.
• The industry is highly water-intensive. Each tonne of hide/skin
tanned requires over 40,000 liters of water.
• Hence even a small tannery with a capacity to process 3 to 4 tonnes a
day uses up well over 100,000 liters of water a day—the daily
household requirement of at least 2,500 people.
• The pollution control authorities have been following their routine
procedures in bringing the pollution from the tanneries under control.
11. The Issue of Water
• The availability of water has become another worry for the industry.
Earlier, the River Palar in North Arcot provided enough water for the
process.
• Failing this, the plentiful availability of groundwater had been
sufficient to meet their needs. Now, over the years, the surface water
sources have dried up.
• The increasing population competes with the growing industry for
this scarce resource.
• The groundwater table in most places has been going down with
overexploitation. The available groundwater is polluted with effluents
and highly saline.
12. The Present Approach
• The pollution control authorities, as well as a number of research
institutions such as the Central Leather Research Institute in Chennai,
have been working to develop systems and processes to help the
industry to conform to the law.
• The United Nations Industrial Development Organization (UNIDO)
also has a special program for working on issues concerning the
pollution from tanning.
• As most of the tanneries are in the small-scale sector and cannot
afford expensive treatment systems on their own, Central Effluent
Treatment Plants (CETPs) are being established under the aegis of the
local industry association. Although this is helping to some extent.
• The water after treatment is still not fit for re-use by the industry
because by the population
13. The Present Approach
• One major problem continues to be the high salinity of the water.
• In addition, there is no answer as of now to the huge quantity of solid
waste generated from water treatment (the quantity is estimated at
150 kilograms per tonne of hide tanned).
• Since the solid waste is carelessly disposed of, it finds its way into the
groundwater during the seasonal rains.
14. A Direction to a Solution:
• One of the possible approaches that emerged was that the industry
could draw seawater, as the state of Tamil Nadu has a long coastline.
The current process parameters do not permit the use of seawater.
This could be a possible direction to research for the industry.
• If this is not feasible, then the industry would have to desalinate the
sea water for its use and internalize the cost of desalination.
Desalination of seawater is an expensive and energy intensive
process.
15. • The cost of energy has to be minimized. One possibility is the use of
the waste heat from a power plant.
• Many new thermal power plants are being planned in the state and it
may be possible to use waste heat from one of the plants to
desalinate water.
16. SOLUTION FOR THE CASE STUDY:
• Relocate all the tanneries along the coast
• Set up power plant close to the tannery cluster
• Use the waste heat from the power plant desalinate water
• Set up central treatment system for the waste water from the
tanneries
• Reuse the waste water in the power plant
• Incinerate the solid waste in the power plant
17. SEA WATER WATER/SALT

18. HOW TO HANDLE THIS PROBLEM:
The three R’s to save the environment :
• REDUCE:
which means using less of natural resource and avoiding wastage of
natural resources
• RECYCLE:
which means the materials like paper,plastic,glass,metals and they are used
for making things can again be used for making new things insteated of
synthesizing or extracting new paper ,plastic, glass etc.,
• REUSE:
which using things again like plastic bottles in which we buy jams,pickels
etc., can be again used for storing things in the kitchen
19. CONCLUSION :
The natural and energy resources should be used
wisely, judiciously, preciously and in such a
manner that they are present for future
generations to come i.e., sustainable
management.
