C1 Flashcards
Human impact (3)
overexploitation of resources
habitat destruction
pollution
If natural resources
are consumed faster ‘
than they can be
regenerated and their
regenerative capacity
is thus overstretched.
overexploitation
Overexploitation o f Different
Types o f Resources (5)
Fisheries
Forests
Water resources
Mineral and energy
Wildlife
happens when fish are harvested
from oceans, rivers, or lakes at a rate faster
than they can reproduce.
Overfishing/ fisheries overexploitation
Unsustainable logging practices, such as clear-
cutting or illegal logging, result in
deforestation and habitat destruction.
forests overexploitaion
occurs when more water is withdrawn from rivers,
lakes, or aquifers than can be naturally
replenished.
Overexploitation of water resources
Extraction of minerals and fossil fuels through
mining and drilling can lead to overexploitation of ____
mineral and energy
occurs through
activities such as illegal hunting, poaching, and
trade in endangered species and their parts.
Overexploitation of wildlife
Consequences of overexploitation (6)
-Loss of biodiversity
-Ecosystem degradation and collapse
-Decline in Ecosystem services
-Economic loss for resource-dependent communities
-Social conflicts over resources
-Increased vulnerability to climate change impacts
elimination or alteration of
the conditions necessary f o r
animals and plants to survive,
not only impacts individual
species but the health of the
global ecosystem.
habitat destruction
Habitat
loss is primarily, though not
always, ___
human-caused.
Human Activities are the
Primary Drivers of Habitat
Destruction : (6)
Deforestation
Urbanization
Agricultural activities
Mining
Pollution
Climate change
Clearing of forests for agricultural expansion,
logging, urbanization, and infrastructure
development is a major cause of habitat
destruction.
Deforestation
The expansion of cities, roads, highways,
dams, mines, and other infrastructure projects
often involves the conversion of natural
habitats into built environments.
Urbanization
Converting natural habitats into agricultural
land for crop cultivation and livestock grazing
is another significant drive
Agricultural activities
extractive industries, including mining and
quarrying, can cause significant habitat
destruction through excavation, land
clearance, and waste disposal.
mining
___from industrial discharge, agricultural
runoff, urban waste, and other sources
Pollution
can alter
habitats through shifts in temperature,
precipitation patterns, and sea levels.
Global warming and climate change
the introduction of harmful
materials into the
environment. These harmful
materials are called__.
Pollution; pollutants
Types of Pollution (6)
Air
water
soil
noise
light
plastic
This includes the release of pollutants into the
atmosphere from sources such as industrial
emissions, vehicle exhaust, burning of fossil
fuels, agricultural activities, and wildfires.
air pollution
occurs when contaminants are
discharged into water bodies such as rivers,
lakes, oceans, and groundwater.
Water pollution
results from the accumulation of
hazardous substances in the soil, often due to
industrial activities, mining, improper waste
disposal, and the use of agrochemicals.
Soil pollution
refers to excessive or
disruptive noise levels from sources such as
traffic, industrial machinery, construction
activities, airports, and urban areas.
Noise pollution
