B. Disruption of food webs
is another consequence of the introduction of non-native species. The new species may not fit well 
into the existing food web, and can upset the balance of predator-prey relationships. For example, if a 
non-native predator is introduced into an ecosystem, it may eradicate a native prey species, leading to 
a cascade effect throughout the food web. This can have devastating impacts on other native species 
that rely on that prey for survival. Additionally, non-native plant species can outcompete native ones for 
resources, disrupting the food web in different ways. Disruption of food webs can alter the structure and 
function of an ecosystem, affecting everything from nutrient cycling to energy flow. Indigenous animals 
may also change their behaviour in response to changes in the food web, further compounding the effects. 
Ultimately, the introduction of non-native species can create a domino effect, with negative impacts across 
entire ecosystems.
C. Alteration of ecosystems
Another key issue in the alteration of ecosystems is the introduction of non-native species. Often brought 
in intentionally or unintentionally, these species can upset the balance of an ecosystem and cause harm 
to native species. For example, the introduction of the cane toad to Australia has had disastrous effects 
on the country's biodiversity. Originally brought in to control pests, the toads have no natural predators 
in Australia and have reproduced rapidly, competing with native species for resources and preying on 
smaller animals. Similarly, in the United States, the introduction of the Asian carp to the Mississippi River 
has caused concern for native fish populations and the economy of the fishing industry. In both cases, 
the introduction of these non-native species has had a significant impact on the ecosystems in question, 
highlighting the importance of carefully considering the potential consequences of human actions on the 
natural world.
In addition to the environmental and economic benefits of reintroducing extinct animals, there are also 
ethical considerations to take into account. As humans, we have a responsibility to repair the damage we 
have done to the planet and its biodiversity. Bringing back extinct species is one way to do that. However, 
some argue that we should not play God and interfere with nature in this way. There are also concerns 
about the practicality of reintroducing extinct animals into the wild. Can we guarantee their safety and 
survival? Will they disrupt the ecosystem in unforeseen ways? These are important questions that must 
be addressed before any reintroduction efforts are undertaken. At the same time, we must also consider 
the implications of not taking action. If we do nothing, more and more species will continue to go extinct, 
and we will lose precious biodiversity forever. Ultimately, the decision to reintroduce extinct animals is 
a complex and nuanced one that requires careful consideration of all the factors involved.
