Chapter 59 & 60- Ecological Impact of Humans & Conservation Ecology

Climate Change

Long-term changes in temperature, precipitation patterns, and other aspects of Earth's climate.

Habitat Loss

Destruction of natural habitats due to agriculture, urbanization, logging, etc.

Invasive Species

Non-native species that outcompete or prey on native species, disrupting local ecosystems.

Pollution

Contamination of air, water, and land with harmful chemicals, plastics, and waste.

Overexploitation

Overharvesting of resources (e.g., overfishing, hunting, deforestation) faster than they can replenish.

Biodiversity

The variety of life in the world or in a particular habitat or ecosystem.

Genetic Diversity

The variety of genes within a species, essential for adaptation and survival in changing environments.

Species Diversity

The number of different species in a particular area, leading to more stable ecosystems and resilience to disturbances.

Ecosystem Diversity

The variety of ecosystems in a region or across the globe, providing unique services and supporting different species.

Ecosystem Services

Essential functions provided by biodiversity, such as pollination, water purification, climate regulation, and soil fertility.

Endangered Species Act

Aims to protect and recover species at risk of extinction by preventing harmful activities and restoring habitats.

Biological Magnification

The process by which harmful chemicals become more concentrated as they move up the food chain.

Greenhouse Effect

The trapping of heat by greenhouse gases after sunlight is absorbed by Earth.

Nutrient Runoff

The washing away of fertilizers into rivers and oceans, causing eutrophication and harmful algal blooms.

H.I.P.P.O.

Habitat loss, Invasive species, Pollution, Population growth, Overexploitation.

Resilience

The ability of a diverse ecosystem to recover from disturbances like natural disasters or disease.
