Climate is the main thing that control vegetation, being the start of the growth process and human kind can control the climate. With our excessive amounts of abuse of the environment we are not allowing earth to naturally control and regulate its self. “Within the last thirty years, for instance, vegetation activity has increased in the northern hemisphere but declined in the southern hemisphere (Schaepman).” Over all there have been drastic changes in the ecosystem due to humans activity, from driving cars to desecrating forests and it is only worsening. If nothing is done about these changes it is not known exactly what will happen but predictions of worsening living conditions have been made.
“The majority of the changes – more than 30 percent overall – were caused by human activity (Schaeoman).” This article talks about the largeness of our effect of the environment, and gives insight to just how bad it is and could be. With this information known and public it’s time to start changing out ways.
