We don't know because we haven't seen the video.
A viewpoint expressed in the video material emphasizes the idea that every type of species has its meaning and purpose, and is important part of biodiversity. Unique characteristics of different species contain the secret of harmony in the world, benefiting from each other by becoming a vital link in the food chain or a remedy to healthier environment.
I believe that all species are connected whether directly or indirectly, and play a significant role in each otherís existence. Extinction of one or the other species might not affect the rest of the biodiversity immediately; however, it triggers irreversible changes in the global food web. It would be childish to think that extinction of one type of birds, for example, would go unnoticed within the global ecosystem, as there might be other species depending directly on this particular type of birds. Extinction of species create imbalance in the food web, which, consequently, results in deficiencies and metamorphic changes affecting other species in biodiversity. Every species in the nature is relevant and is serving its reason, even if it seems insignificant from human perspective.
A viewpoint in the video that I saw was that we need to preserve nature and all the living species in it, each species has its importance in this world. If we do not than we are potentially losing out on things that could benefit humans like scientist Tom Eisner has done in Florida with animals and plants. Yes, I believe that each species is connected especially when it comes to nature and the habitats they live in. Nature has a very unique way of living and surviving in nature and how they use other species to do so.
