EVOLUTION LIN K Because new species will eventually evolve...

Key Concepts

Ecosystem Interdependence

Ecosystems are made up of interconnected species that rely on each other for processes such as pollination, nutrient cycling, and energy flow. The loss of one species can disrupt these interactions, leading to further extinctions and degradation of ecosystem functions. This interdependence means that preserving biodiversity is essential to maintain the stability and productivity of ecosystems on which human societies depend.

Species Extinction

Species extinction is the loss of individual species from the planet, which directly reduces biodiversity. Each extinction represents the elimination of unique evolutionary histories and ecological roles, many of which are integral to ecosystem balance and functionality. The irreversible nature of extinctions can lead to cascading effects throughout ecosystems that undermine their ability to support life.

Biological Diversity

Biological diversity refers to the variety of life in all its forms, including genetic, species, and ecosystem diversity. It is critical because it underpins the resilience of ecosystems, ensures a range of ecosystem services, and provides the raw materials for adaptation and evolution. Loss of biodiversity disrupts these functions, reducing the capacity of ecosystems to withstand environmental changes and human impacts.

Evolution

Evolution is the process by which species adapt and change over time through mechanisms such as natural selection, mutation, and genetic drift. While evolution can lead to the emergence of new species, it is a slow process that cannot quickly replace the complex interactions and functions established by extinct species. This means that waiting for evolution to replace lost species may not adequately address the immediate and long-term consequences of biodiversity decline.

Transcript

00:01 Today we're going to be discussing about this question about because new species will eventually evolve to replace those that humans are driving to extinction.

00:15 Why is declining biological diversity such a threat? and the reason why because when you look at the term biological diversity is based on a no, biodiversity.

00:44 The term with that means, you know, the variation.

00:54 The variation among organisms.

01:02 And we also got to bring in about species richness, which is also just means the number of species, you know, the number of species of, you know, the number of species of, you know, archa bacteria, protis, plants, and animal.

02:01 So even though you might have a new species that will evolve to replace the ones of the human decline, they're wondering why would biological decline of biodiversity is such a threat.

02:20 The issue is like, how we know these new species, you know, are actually good for, how i know that these species that are coming in would actually provide something helpful or these are species that might cause some, oops, economic or environmental harm.

02:54 Also known, also another turn to call them are invasive.

03:01 Species.

03:10 So with that, some of these invasive species might cause more harm financially or environmental harm where it's like they might affect other parts of the biotype, you know, other animals or other plants and things of that nature.

03:31 And also with that, when a new one involves, the old one that is slow again away...
