24
Q

This refers to changes in the natural structure of species and their interactions within an ecosystem.

A

Alteration in Ecosystem Compostion

25
The causes for alteration of ecosystems can be classified into two primary categories:
Natural Causes Anthropogenic (human-caused) causes
26
NATURAL causes for alteration of ecosystems
Volcanic eruptions Floods Wildfires Wildstorms Landslides
27
ANTHROPOGENIC causes for alteration of ecosystems
Habitat destruction Deforestation Pollution Invasive species Overexploitation
28
Non-native species introduced intentionally or accidentally. Thrive aggressively in new ecosystems due to lack of predators. Major threat to biodiversity
Invasive Species
29
Effects of Invasive Species
Competition for Resources Predation on Native Species Alteration of Food Chains Alteration of Habitat Conditions Spread of Diseases/Parasites
30
Harvesting natural resources at a rate that exceeds Earth's ability to replenish them
Over-Exploitation
31
Key Activities in Over-Exploitation
Overhunting Overfishing Deforestation Mining
32
Catching fish faster than they can reproduce Leads to a decline in fish populations
Overfishing
33
Illegal hunting/capturing of wild animals Causes significant population declines
Hunting & Poaching
34
Impacts of Over-Exploitation
Climate Change Acceleration Decline in Ecosystem Services Economic & Social Impacts
35
The emission of harmful agents (toxic chemicals, waste) into the environment. Causes irreversible damage to species, ecosystems, and human health.
Pollution and Contamination
36
Types of Pollution
Water Pollution Air Pollution Soil Pollution
37
Contamination of rivers, lakes, oceans, and groundwater Makes water unsafe for humans, animals, and ecosystems
Water Pollution
38
Presence of harmful substances (gases, dust, smoke, chemicals) in the air Negatively affects human health, animals, and the environment
Air Pollution
39
Contamination of soil with chemicals, heavy metals, pesticides, and industrial waste Makes soil toxic for plants, animals, and humans
Soil Pollution
40
Effects of Pollution and Contamination on Biodiversity
Animal Health Human Health Population Decline
41
A long-term change in Earth's weather patterns, including shifts in temperature, precipitation, and other atmospheric conditions over decades or longer
Global Climate Change
42
Threats of Global Climate Change to Biodiversity
Habitat Loss and Destruction Relocation of Species Breeding and Migration Cycle Disruptions
43
Ecological Consequences
Ecosystem Imbalance Loss of Ecosystem Services Increased Vulnerability to Climate Change
44
Economic Impact
Decline in Agriculture and Fisheries Tourism Damage Higher Disaster Costs Medical Costs
45
Social Impact
Threats to Indigenous Communities Food and Water Scarcity Health Issues Cultural Loss
46
Nutrition and biodiversity are linked at many levels:
The ecosystem, with food production as ecosystem service Species in the ecosystem Genetic diversity within species
47
Environment Related Illnesses
Heart Disease Asthma Cancer Diabetes Malaria Respiratory Infections
48
A chronic respiratory disease where the airways become inflamed and narrow, causing difficulty breathing.
Asthma
48
A range of conditions affecting the heart, such as coronary artery disease, heart attacks, and heart failure.
Heart Disease
49
Uncontrolled growth of abnormal cells in the body that leads to tumors.
Cancer
50
A condition that impairs the body's ability to regulate blood sugar levels, leading to high glucose levels in the blood.
Diabetes
51
A mosquito-borne infectious disease caused by Plasmodium parasites, characterized by fever, chills, and flu-like symptoms.
Malaria
52
Infections that affect the respiratory system, such as pneumonia and bronchitis.
Respiratory Infections
