Study Notes
Nitrate and Soil
- Excess nitrate in soil can lead to harmful conditions such as groundwater contamination and eutrophication in aquatic systems.
Bioaccumulation Risks
- Bioaccumulation of non-biodegradable pesticides poses a major risk of biomagnification, where toxins increase in concentration at higher trophic levels, affecting predators and humans.
Fertilizer Usage Issues
- Excessive use of fertilizers in modern agriculture commonly results in nutrient runoff, contributing to water pollution and algal blooms.
Pesticides and Non-Target Organisms
- Overuse of pesticides harms non-target organisms, disrupting ecosystems by reducing biodiversity and harming beneficial species like pollinators.
Consequences of Eutrophication
- Eutrophication results in oxygen depletion in water bodies, leading to dead zones where aquatic life cannot survive.
Modern Agriculture Problems
- Problems associated with modern agriculture include soil degradation, loss of biodiversity, and water contamination through fertilizers and pesticides.
Habitat Fragmentation
- Habitat fragmentation refers to dividing a landscape into smaller, isolated patches, detrimental to wildlife movement and genetic diversity.
Plant Species Extinction
- The extinction of wild plant species, crucial for hybrid seed production, is primarily driven by habitat loss and monoculture farming practices.
Impact of Wetland Destruction
- Destruction of wetlands, estuaries, and mangroves significantly impacts biodiversity by eliminating critical habitats for numerous species.
Wildlife and Habitat Loss
- Human activities involving wildlife trade and poaching contribute to habitat loss and reduction in biodiversity.
Dams and Industrial Effluents
- Construction of dams alters water flow and habitat while industrial effluents introduce pollutants, both of which adversely affect biodiversity.
Pressures on Forest Resources
- Increased population and urbanization intensify pressure on forest resources in India, leading to habitat degradation and deforestation.
Water Logging Causes
- Poor drainage, excessive irrigation, and rainfall lead to water logging, negatively affecting soil health and agricultural productivity.
Energy Consumption Comparison
- Developed countries exhibit higher energy consumption levels due to industrialization, urbanization, and lifestyle demands.
Remedies for Water Logging
- Implementing improved drainage systems is a potential remedy for managing and reducing water logging problems.
Pesticides in Soft Drinks
- The presence of pesticides in soft drinks poses health risks to consumers, raising concerns about food safety.
Sustainable Energy Resources
- Renewable energy sources such as solar, wind, and biomass align with sustainable development goals by reducing environmental impact.
Non-Renewable Energy Challenges
- A significant challenge associated with non-renewable energy resources is their finite availability and the environmental degradation associated with their extraction and use.
