Key Concepts

Climate Change and Sea Level Rise

Climate change encompasses long-term shifts in temperature and weather patterns, primarily driven by human activities such as the burning of fossil fuels. One of its impacts is rising sea levels, which can lead to the flooding of coastal habitats and the loss of land crucial for many species’ survival. Although rising sea levels affect ecosystems, they are part of a broader climate change narrative rather than acting as an isolated or primary driver of extinctions like habitat destruction or overexploitation.

Overexploitation

Overexploitation refers to the unsustainable use of natural resources, including the harvesting of wild species for food, medicine, or other purposes at rates faster than they can naturally replenish. This pressure can drive species to the brink of extinction, making overexploitation a critical concern in conservation efforts.

Invasive Species

Invasive species are non-native organisms that are introduced into new environments where they can outcompete local species, often leading to significant ecological imbalances. While invasive species, including introduced predators or pathogens, can have severe impacts on native biodiversity, they are typically one of several factors that contribute to species declines rather than a dominant cause of global extinctions.

Species Extinction

Species extinction refers to the complete loss of a species from Earth, a process that can occur naturally over geological timescales but has accelerated due to human activities. It is a central concept in conservation biology and ecology, as it signifies the irretrievable loss of biodiversity and the disruption of ecosystems which rely on diverse species interactions.

Habitat Destruction

Habitat destruction is the process by which natural environments are altered or eliminated, often through human activities like deforestation, urbanization, and agriculture. It is considered one of the primary drivers of species extinction because it removes the necessary living and breeding spaces for many organisms, leading to population declines and eventual extinction.

00:02 Hi there.

00:03 Species extinctions are a huge threat to biodiversity.

00:10 And something scientists have been noting of late is that the rate of extinctions has been increasing.

00:20 So this question wants to know which of the things there are not currently considered a threat to these species extinctions.

00:30 I finish writing my threat to biodiversity here.

00:35 All right, so let's look at each of these.

00:37 The first one is habitat, destruction.

00:41 Habitat destruction means that we are destroying habitats.

00:46 We are cutting down trees.

00:48 We are building buildings.

00:49 We are paving over habitats.

00:52 We are changing the way rivers flow and on and on and on.

00:58 So destroying habitats definitely affects the species that formerly formerly live there.

01:07 So this one is a threat to species and it causes an increase in extinction.

01:16 Let me skip letter b for a moment.

01:18 Let's talk about over exploitation.

01:21 This could include things like overfishing or over hunting or over harvesting trees, cutting down entire, entire, you know, patches of woods, again destroying habitats.

01:37 These would also contribute to the loss of species...
