Human Impact on Ecosystems and Conservation Strategies

Habitat destruction

The process of eliminating or altering natural habitats, making them unsuitable for species.

Habitat fragmentation

The division of large habitats into smaller, isolated patches.

Habitat degradation

The decline in habitat quality due to pollution, climate change, or invasive species.

Invasive species

Introduction of Non-native species into ecosystems, disrupting local biodiversity.

Unsustainable use of resources

Overexploitation of natural resources beyond their renewal rate.

Impact of pollutants (biomagnification)

The accumulation of toxins in organisms at higher trophic levels.

Climate change

Long-term shifts in temperature and weather patterns due to human activities.

Migration

Species relocate due to environmental changes affecting ecosystems.

Eutrophication

Excessive nutrient build-up in water bodies, leading to algal blooms and oxygen depletion.

Deforestation

Amazon rainforest expansion, agriculture, and mining destroy ecosystems.

Habitat fragmentation example

Roads, cities, and farmland break up ecosystems, limiting species movement.

Ecosystem degradation example

Overgrazing, industrial pollution, and soil salinity degrade ecosystems.

Invasive species introduction example

Global trade, pet releases, and accidental transport introduce invasive species.

Resource overexploitation example

Overfishing, deforestation, excessive water use, and mining.

Pollutant impact example

Industrial waste, pesticides, and heavy metals enter food chains.

Greenhouse gas increase example

Burning fossil fuels, deforestation, and industrial emissions increase greenhouse gases.

Species migration example

Climate shifts, habitat loss, and human activities force species migration.

Nutrient introduction example

Agricultural runoff, sewage discharge, and industrial waste introduce excess nutrients.

Wildlife corridors disruption example

Wildlife corridors disrupted by highways.

Dryland salinity example

Dryland salinity in Australia: excessive irrigation leads to salt accumulation.

Cane toads impact example

Cane toads in Australia harming native wildlife.

Cod fisheries collapse example

Collapse of cod fisheries in the North Atlantic.

Mercury accumulation example

Mercury accumulation in fish affecting human health.

Coral bleaching example

Coral bleaching due to rising ocean temperatures.

Polar bears migration example

Polar bears moving further inland due to melting ice.

Dead zones example

Dead zones in the Gulf of Mexico due to fertilizer runoff.

Conservation strategies

Protected areas, reforestation, sustainable land use.

Wildlife management strategies

Wildlife corridors, habitat restoration, sustainable urban planning.

Salinity management strategies

Salinity management, afforestation, sustainable farming practices.

Biological control strategies

Biological control, habitat restoration, strict biosecurity measures.

Sustainable resource management

Sustainable harvesting, quotas, renewable resource management.

Pollution control strategies

Pollution control, banning harmful chemicals, ecosystem monitoring.

Renewable energy strategies

Renewable energy, carbon sequestration, afforestation.

Habitat protection strategies

Habitat protection, migration corridors, climate adaptation strategies.

Fertilizer use reduction strategies

Reducing fertilizer use, wastewater treatment, wetland restoration.
