Parasites

 

   Parasite population grows on a diverse landscape. This landscape may include deserts, rainforests, swamps, parks, water bodies and even human body. There are many different types of parasites. Each parasite has its own habitat, a way of reproducing, size, length and so on.

   One of the parasites that affect humans is the guinea worm. “Water fleas” in water development into these worms that form blisters on human body and skin. Pouring water on blisters makes this infection worse where these parasites may even grow up to a meter and live for years. These parasites produce thousands of offspring if not millions. Hence, removal method for these parasites is time-consuming since one may only remove the meter long worm, few centimeters at a time. Another parasite is the head lice. These lice live in human hair and feed on human blood. They have changed European history as they spread the plague. These lice jump from person to person making it impossible to stop their spread. Even fish are not free from parasites. Parasites in water grow in fish and end up in human blood as a result of untreated fresh fish consumption. Tapeworms, for example, can reach ten to fifteen meters of wild freshwater fish that is consumed uncooked. Usually gutting and freezing fish kills these parasites but one may never be careful enough. Parasites like roundworms and their larger cousins affect twenty-five percent of the world’s population. One single worm affects twenty-six million people in its lifetime and as much as five thousand have been removed from a single person. These worms grow up to twenty-five to thirty centimeters long and may only be removed by methods like endoscopy. Also, there are few parasite types that consume blood cells of veins and arteries. These parasites develop in different stages where they bounce back and forth between human hosts and other hosts like snails in water. Ultimately, they end up causing cancer and liver complications. “Filarial worms” are another forms of parasites that reproduce in the human blood causing swelling and disfiguring in a condition called “Elephantiasis”. Some parasites that grow in human blood are even more deadly. Black fly causes parasitic disease responsible for river blindness and reptilian skin. Lastly, even with all these parasites combined, no other parasites cause as much damage as Malaria. This disease is caused by single-celled parasites and their mosquito hosts. This disease kills three million people every year and is considered more deadly than the biggest cats as well as the largest crocodiles alive. Overall, there are many types and forms of parasites, one deadlier than the other.

   In conclusion, parasites cause damage to lives and property. Carpets, upholstery, and mats with any form of the parasite may be considered useless and lose value. Pets that bring parasites into homes must be properly groomed, cleaned and looked after. Also, landscaping with carnivorous plants that feed on mosquito as well as insects may reduce mosquito population as well as the parasites that they bring.
