Over the years, humans have slowly impacted our environment and its species
As our world moves forward; creating new and innovative ideas that bring convenience to ourselves we are oblivious to the negative impact it has on biodiversity. Human activities are held largely responsible for our ever changing environment as well as the threatened species in it. From cutting down trees to over fishing, we are only risking the well being of our environment.
Although we've come far to get at this point, we've effected the earth more negatively than we'd have liked. Human activities such as fishing and agriculture have affected the ecosystem through the damage of their habitats. Face it or not- we're all guilty of contributing some kind of harm towards one specie or another. Human activities such as hunting and forestry are only a few factors to the reason why we have a threatened ecosystem.
As you've noticed, there has been a huge growth of human population over some time now.So you're asking yourself, how did this disaster come to be? Well, it started with the increase in the human population. The need for resources such as food and lumber increased in exchange for our survival. However, with the booming businesses of fishing and lumber industries, our biodiversity was left to suffer due to the increasing demand of resources from humans.
Along the way, habitats have been destroyed because of our invasive ways. Species such as deers have been forced to adapt to different habitats because of the on going transformation of their surroundings. Without their proper habitats, maintaining a healthy environment for them to produce actively decreases along with the resources available for them to sustain life. The lack of these essential eventually lead to the extinction of a variety of species. According to the World Conservation Monitoring center, the highest cause of animal extinction is due to Habitat Destruction
Aside from human population and habitat destruction being factors to our threatened biodiversity, activities such as hunting have caused a disruption to our ecosystem. The disturbing part of this is the fact that the majority of hunting is done illegally, also known as poaching. Over hunting has led to the extinction of many species, these vast majority of extinct species then create the domino effect, which occurs when the food chain is derailed and all of its involved organism are affected.
By now i think that most organism on this earth look to us as their mortal enemy, the people who bring darkness and despair to their lives- if we were stewards of the world I doubt we would even be in this mess!
The whole ecosystem is affected by one another, when human population increases, the need for resources also increases to suit our needs. When there are more of us, the more accommodation is needed for us to sustain our survival on earth, but we are oblivious to the harm we bring to the rest of the species we live with. The majority of the re-occurring issues we face today that involves biodiversity can simply be blamed on humans. We are, in my opinion, the most intellectual beings on this earth, with such power I think that we have the potential to serve it with the dignity it needs.
