Water pollution
Water pollution has many negative effects including the death of aquatic animals, disruption of food chains, spread of diseases to humans, and destruction of ecosystems. Pollutants are absorbed by small organisms and concentrate up the food chain, eventually poisoning animals and humans. Water pollution also has economic costs such as increased water purification costs and losses to fishing and tourism industries. Control measures include proper waste disposal, reducing chemical usage, water conservation, and government regulations on industry and sewage treatment.
Water Pollution
Water pollution throughout the world is affecting food chains and food webs. Water such as lakes, rivers, streams, creeks, and oceans become polluted in many different ways. One main way is the dumping of trash, or littering. Many creeks, rivers, and even oceans have been polluted by manmade items such as trash (EPA, 2011). When fresh water such as rivers and creeks become polluted, it hurts the surrounding wildlife.

Water pollution occurs when bodies of water become contaminated by harmful substances, making the water unfit for its intended use. There are two main types of pollution: point source pollution which comes directly from an identifiable source, and nonpoint source pollution which comes indirectly from diffuse sources like farm runoff. Common causes of water pollution include sewage, excess nutrients from fertilizers which can cause algal blooms, silt from construction sites, and organic waste which reduces oxygen levels in water. A wide variety of chemicals and pathogens can also pollute water supplies and disrupt ecosystems.
Sec 2 Exp Water Pollution
Sewage and industrial waste contain harmful substances that pollute water bodies when improperly disposed of. Non-biodegradable substances like detergents remain in water and cause pollution. Water pollution endangers plant and animal species by disrupting insulation and clogging feathers/fur, and poses negative health impacts as poisons accumulate in seafood. It also causes economic losses through impacts on fisheries, tourism, and costly oil spill cleanups.

Eutrophication ppt
Eutrophication in aquatic ecosystems is caused by excessive nutrients which enhance algal growth. This can have negative effects like algal blooms, oxygen depletion, and fish kills. Nutrients enter waterbodies from both point sources like wastewater effluents and non-point sources like agricultural runoff. Consequences of eutrophication include dominance of cyanobacteria, increased plankton-eating fish populations, and reduced diversity. Prevention methods include removing excess plants, adding competitors/predators of algae, oxygenating water, using herbicides/algaecides, banning phosphates in cleaners, and improving wastewater treatment to remove nutrients. Cultural eutrophication is accelerated by human activities like agriculture

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UP
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.
