When we think about climate change, we are aware that it is a large-scale climate change that takes place as a consequence of human actions on the planet. However, climate is a system that is constantly changing by itself. In this way, regardless of human actions, we find that ecosystems manifest themselves as the living entities that they are, changing and adapting to new circumstances that may occur. In this way, we can find natural changes and artificial changes that affect ecosystems and that modify them, sometimes for the better and others for the worse.
If you want to know some examples of natural and artificial changes in ecosystems, as well as the consequences that these have on these systems, keep reading Green Ecologist and we will tell you about it.
Speaking of ecosystem, refers to a system that is made up of two main elements: the living beings that make it up and the physical space in which these living beings inhabit. In this way, to speak of an ecosystem is to speak of a biological character system that is delimited within a specific physical space.
Because the physical space is one of the key elements when determining the characteristics of an ecosystemIt is possible to speak of as many ecosystems as there are physical spaces, as long as there is biological activity in them. In this way, there are some well-known ecosystems, such as forests, seas or rivers, mountains, or even deserts. However, it is also fair to speak of ecosystems when we refer to spaces where biological life has adapted to very particular conditions, such as those that occur in marine trenches, in underground caves or, simply, those that occur in cities and human population centers, which are also ecosystems in themselves, although with a marked artificial character as they are linked to the human being.
On the other hand, one of the elements that cannot be avoided when talking about ecosystems is that, beyond the importance of mentioning spaces where different species have their habitat, these species establish relationships with each other. These relationships can be of many types, from cooperation and symbiosis to predation or competition with each other. All this constitutes the intrinsic nature of the ecosystem, which must be understood as a single unit despite being clearly composed of a multiplicity.

One of the elements that must also be considered when talking about ecosystems is that, although they are systems, which implies a certain intrinsic order in itself, they are systems open to change. In other words, ecosystems tend to balance naturally, but that, if a new element appears that modifies said balance, a change will be generated in the ecosystem, which will tend to assume it as its own and try to adapt to said change. However, success or failure in adapting to this change will determine the survival of the ecosystem as a whole.
In this way, it is the new elements that allow the tasks to be carried out. changes in ecosystems. In this sense, a new element can be a disease that affects a part of the trophic chain, which will cause that, even if it only affects one species, the entire ecosystem as a whole is affected by the domino effect that this will generate. Or there can also be a change in an ecosystem due to something as simple as climatic changes in the environment that modify the presence of rainfall, causing there to be more or less vegetation.
One of the factors that must be taken into account when changes in ecosystems occur is that, the slower these changes are, the more possibilities the ecosystem in question will have of surviving these changes, since it will have more possibilities to adapt successfully to the new tessitura. On the contrary, if the changes manifest themselves very quickly, it is very likely that many species are unable to adapt to the new modifications and, consequently, may reach disappear or disappear of said ecosystem.
One of the problems presented by artificial changes in ecosystems (that is, caused by humans) is that they are changes that take place very quickly. In this way, the majority of species cannot adapt to these changes and end up being displaced or suppressed from the ecosystem. On the contrary, natural changes in ecosystems tend to occur more slowly, allowing species to adapt more successfully and consequently have more chances to survive. However, there are natural changes that can also lead to major extinctions and catastrophic changes to ecosystems.
Here are some examples of natural and man-made or artificial changes in ecosystems, which help us understand the wide variety of possibilities that exist when talking about changes in environments or ecosystems:
