Ecological impacts, Genetic pollution, agricultural damage are some negative effects caused by invasive species. Biological species invasions altered ecological systems in multiple ways. “Worldwide an estimated 80% of endangered species could suffer losses due to competition with or predation by invasive species (panda.org, 2014) ”Some native species may be put at a disadvantage to survive while other species survival is enhanced in physical power due to the change in environment. Genetic pollution might also occur, naturally evolved region specific wild species can be threatened with extinction through the process of genetic pollution. Including, uncontrolled hybridization, introgression (gene flow from one species into the gene pool of another, by the repeated backcrossing of a hybrid with one of its parent species) and genetic aggression and take over, which leads to the replacement of local species as a result in an enchanted advantage of foreign species.
This means the animals may have to relocate, which would result in it being an invasive species, and we all know the unwelcome effects of invasive species. You would have to revive a natural predator and prey for that specific animal to prevent it from disrupting the fragile ecosystem. This itself would cost us millions of dollars, and probably raise taxes. Raising taxes aren’t good. (As of 3/6/18, America is $20,867,726,890,754.58 in debt, and there is $223.3 trillion dollars of world debt) You mentioned
As omnivores face high extinction rates, they may not have sufficient time to undergo speciation and form 2 different species before they go extinct. However, omnivores have not completely vanished due to high transition rates into omnivory. This would only occur when there is low availability of a preferred food source. For instance, an herbivore will only eat plants. Yet, when there are a low number of plants in the environment, herbivorous birds that can also take other food
As previously mentioned, the organisms on these landforms evolve to live in these new environments with success, and to reproduce and form a new generation. The landform shifting can also cause earthquakes, which further shift the land and cause the organisms to evolve further. The earthquakes can also cause mudslides and tsunamis, which can destroy or cover any human-made structures and buildings. The destruction of these human-made structures and buildings an also cause devastating effects to the landmasses on Earth, with the death of organisms being a common factor. As a result, many creatures have gone extinct or have become endangered from the deadly destruction of a
As a result of overpopulation, industrialisation and urbanisation we, as humans, are destroying the natural world that supports millions of other animal species. Our actions interfere with and sometimes destroy entire ecosystems; this will cause animal populations to decline and inevitably go extinct. We need to look at the long term affects our actions are having, we need to investigate what destroying the natural world means for the survival and sustainability of our race and all other species on Earth. One way to investigate this is by focussing on specific interactions that certain species have on their surrounding environment. I have decided to focus on vultures in South Africa because I feel vultures play a very important role by disposing of carrion (dead animals) that would otherwise be a breeding ground for disease and bacteria.
Should extinct species be brought back to earth? In my opinion I think that de-extinction is a bad idea. Take the wooly mammoth for example, if scientists were to bring it back they could be taking resources away from other species causing them to disappear, humans might try to harm other animals that aren’t extinct, and scientists would have to successfully re-introduce this animal back into the lifestyle they used to have. Although some people believe that de-extinction is a good thing, I strongly disagree because of those three reasons. One reason that de-extinction is a horrible idea is that the species, lets say a wooly mammoth, could potentially take important resources away from other species causing them to disappear.
Unearthed fossils explain how species changed over time and due to selective pressures, certain traits became more adaptive than others and were amplified throughout the species. Intelligent Design is a theory that cannot be replicated and therefore is a pseudo-science. One can replicate Darwinism with bacteria which has a fast reproductive cycle, and have a population and a variable population placing them in different conditions and replicating the same experiment to see if you obtain the same results. This supporting evidence suggests that Darwinism is the more likely of the two
Many communities are impacted by exotic species that are introduced over time (Lankau 2009). These exoctic species can result in either positive or negative effects on the community through interacting with the native species (Lankau 2009). Exotic species are moved by humans outside of their native range; species become invasive when they cause harm to their new environment. Earthworms are exotic in many areas that they are introduced to over time. Earthworms are a major influence on soil composition, but to this day there is still many unknown factors about the species (Zirbes L et.
The expensive process can create a gap between designer babies and non-designer babies and rich and poor babies. There are desired traits, so there would be a lack of societal diversity, with everyone having the same traits. The procedure can create a random gene that interrupts another gene or create a new disease. The contagious disease can spread all over the country if the baby survives. Decimating the population might seem like a good idea, but it can go too far too fast.
Certain species have a huge impact to an ecosystem, but even the smallest fish could have the biggest impact. Overfishing occurs when more fish are caught than the population can replace through natural reproduction (overfishing). The results not only affect the balance of life in the oceans, but could also affect the coastal areas that depend on fish for their way of life. For centuries, our seas and oceans seem to be considered a limitless food supply. But that is not the case, increasing fishing efforts over the last fifty years as well as unjustifiable fishing practices are pushing many fish stocks to the point of extinction.
