especially rivers, may lead to intoxication and hence diseases to living organisms depending
on the water.
Human-wildlife conflict has also been rampant with population growth. With
population growth increasing gradually, the need for human settlement is also critically
important. Therefore, more people encroach forests leading greatly to disruption of the
ecosystem through displacement of animal and other organisms from their natural habitat.
Also with human encroachment, illegal hunting is inevitable to source valuable products such
as tasks (Animal Rescue Crusade), hides and at times meat for family consumption.
Humans have greatly impacted positively the environment. First, humans have been
conducting numerous research on cross-breeding, most importantly on tamed animals such as
cows and some agricultural plants, on how to increase yield. This has resulted in high
production thus ensuring food security. Plant grafting has ensured healthy agricultural
products for human consumption. However, despite the reason, this has greatly impacted the
flora and fauna of such places.
States and private organizations have also accelerated animal and other organism
preservation. Furthermore, while targeting increased revenue collection from tourism, game
reserves, national park services, National Wildlife Refuge System have been founded
preserving rare species both plants and animals. The preservation guarantees existence of
such spices to the future generation. In Kwazulu-Natal, South Africa, in the 19
white rhinos were thought to be extinct spices. However, a small population of fewer than
100 rhinos was discovered, protected and breaded to raise the number to about 21000 rhino
across several game reserves currently (World Wildlife Fund). Through introducing new
species to new localities either for human consumption or for aesthetic purpose, humans have
contributed to the preservation of such species this is a great achievement in environmental
