One of the most commonly known global effects of bioinvasion is global warming. In a study completed by the National Invasive Species Awareness, it was discovered that rising air temperatures affect “marine ecosystems by raising air temperatures, decreasing oceanic pH, altering stream flow patterns, increasing storm events, and contributing to sea level rise”. The overall health of a marine species is dependent on its interaction with the environment. If the condition of the environment is changed by even a degree, marine species are threatened. Many fish in our oceans are heat sensitive and any change in water temperature can demolish a whole species. Just think about how hard it is to have a salt-water fish tank: most people have a hard time keeping fish healthy because the water temperature fluctuates too often. It’s the same sad story with our oceans. With rising temperatures, we are already seeing a loss of the sea-ice habitat with polar bear populations decreasing at alarming rates. Ice is melting at a alarming rate leaving polar bears limited ice caps to live on. Climate change has also increased the occurrence of severe weather around the world. An example would be the recent monsoon in Pakistan that affected nearly 13 million people and killed over 400 people. The three day flood wreaked havoc on northern Pakistan and left many climate scientists concerned for the future. An Article by BBC News described the monsoon to be larger than the combined effects of the three worst natural disasters to strike in the past decade. Climate change is clear indication of the extent of global bioinvasions. A recent study conducted by a group of Purdue students found that “future climate change will influence monsoon dynamics and cause less summer precipitation, a delay in the start of monsoon season, and longer breaks between rainy periods”. These changes will undoubtedly affect the fragile ecosystems who cannot handle the shift in temperature and changing weather patterns. As time goes by and temperatures continue to increase we will be faced with deadly weather systems. We must cut down our carbon emissions and educate others to do the same in order to make a positive change for our environment.
