It’s no secret that wildlife has been severely affected by human activities on the planet. In nearly every corner of the globe, humans have done explorations and left their footprints that have caused effects on wildlife. Our endless greed for discovering more about them and the world we live in in the wrong way, the growth of population, and the never-ending needs of humans have constantly damaged the wildlife.
Wild animals and plants are obtained for food, pets, ornamental plants, leather, tourist souvenirs, and medicine hundreds of millions of times a year. There is a large amount of this trade that is legitimate and does not harm wildlife populations, but a distressingly huge percentage of it is illegal and is threatening endangered species. Aside from drugs, weapons, and human trafficking, illegal wildlife trading is the world’s fourth-largest criminal industry. A few of the world’s most recognizable animals, such as the rhinoceros and the elephant, are in grave danger because of it.
The Climate Change
Climate change is occurring both inevitably and as a result of human activity. Global warming and climate change have already had a significant effect on the spread and behavior patterns of animals, birds, as well as plants. There is an increase in sea level, as well as an increase in the temperature of the oceans. Droughts that last longer and are more severe are a threat to crops, wildlife, and the availability of freshwater. Polar bears in the Arctic and marine sea creatures off the coast of Africa are just two examples of the wide variety of life on our planet that are at risk because of climate change.
The Loss Of Habitat
There is no denying how fragile our planet’s most vital ecosystems are, as evidenced by the recent bushfire epidemic in the Amazon and in Australia. At a rate ten times faster than what can be replenished, half of the world’s original forests have been destroyed. The image of a bulldozer tearing down trees is emblematic of habitat loss. Wetlands are filled in, rivers are dredged up, mowing fields are cut, and trees are felled.
Pollution has the greatest influence on freshwater wildlife. Waterways and wetlands act as sinks for pollutants like untreated sewage, mining wastes and acid rain as well as fertilizers and pesticides that end up in the food chain. In the ocean, there are 500 times as many pieces of microplastic as there are stars. Over 600 species of fish, birds, and other marine life are threatened by plastic pollution that washes up on previously pristine areas of the planet.
Diseases And Invasive Living Things
There are many direct threats to native species from invasive species such as species that feed on them, trying to compete with them for food or other resources, spreading disease, and killing their offspring. Aside from that ,the natural world is full of disease. Viral, bacterial, fungal, and parasitic organisms are common in most ecosystems. Most diseases can be thwarted before they have a chance to do much damage in healthy wildlife and ecosystems.
