Humans can affect biodiversity in many ways. For this discussion board research a specific example of how humans are impacting biodiversity, a different example from the one in the video. Be sure to use your own words in this post. Please answer the following: 1. What is one thing that humans are doing that affects biodiversity? 2. How is that one thing negatively impacting biodiversity? 3. What is a possible action that could be done to change the loss of biodiversity?

Transcript

00:01 One thing that humans are doing which negatively affects biodiversity is habitat destruction fragmentation.

00:20 So, human activities like deforestation, urbanization and converting natural habitats into agricultural land.

00:30 So, these actions of us have significantly altered and reduced natural ecosystems all around the world.

00:38 So, the habitat destruction and fragmentation it can have negative impacts on biodiversity in the following ways.

01:01 So, the first is loss of species and extinction.

01:14 So, when habitats are destroyed, many species they lose their home and so they are like unable to survive.

01:23 So, that leads to like population decline and even some species they like they completely go extinct.

01:30 The second negative impact is disruption of ecological processes.

01:46 So, habitats provide very crucial resources and conditions for different kind of ecological processes like pollination, seed dispersal, even nutrient cycling.

01:57 So, when habitats get fragmented or they get destroyed, then what happens is these processes they also get disrupted and as a result the overall functioning of the ecosystem is disturbed.

02:12 The third reason is decreased genetic diversity.

02:25 So, fragmentation as a result of fragmentation populations get isolated.

02:30 So, there is a very limited gene flow and the risk of inbreeding.

02:37 Since the gene flow decreases, so there is more risk of breeding happening within the population which is called inbreeding.

02:46 So, this reduced genetic diversity it makes the population more vulnerable to diseases, environmental changes and even other threats.

02:57 So, these are the primary negative impacts that happen on biodiversity as a result of habitat destruction and fragmentation.

03:08 And the possible steps that can be taken to mitigate the effects of these things are first is we should establish protected areas and habitat conservation...
