Explanation:
Humans are responsible for the depletion of of wildlife due to the following points:
We used to make paper out of wood pulp and also furniture from wood. We used wood for building and later on cleared forests for mining of minerals and oil. Swathes of forests have been cleared which has resulted in less food for animals and less protection for them. Take Borneo as one example. The Orangutan has less of his jungle habitat to live in as (I believe) the land was stripped of forest to plant Palm trees which yields valuable oil and therefore revenue for the government. This is the kind of thing that humans do to make money. There is a knock on effect when messing around with nature. Bees are diminishing in numbers due to man's interference and other species are dying out.
Women used to want fur coats to wear. A roaring trade began and leopard numbers diminished as well as stoat, jaguar, cheetahs, mink etc., and people like Rooseveldt went on hunting safaris and killed hundreds upon hundreds of wild animals. In those days men believed they had dominion over all others (including women) and didn't think twice about the consequences of their greed and avarice. No one challenged them.
Ignorance played a major hand in both scenarios. When I lived in Zimbabwe we had cattle ranches on the west side of a river (the Tokwe) and our land had lots of grazing land for our cattle. On the east side of the river the earth was scorched without a vestige of vegetation for at least half a mile. This is where native African people lived. They owned cattle and goat's. Whatever vegetation was left by the cattle the goats would devour, roots and all. Their animals depleted all their grazing land and had to move further afield where they repeated the same bad grazing habits and caused the bare earth to get Sun scorched. Consequently we decided to teach them the value of rotational grazing and many of them realized why we always had grass on our lands.
Humans have also taken a lot of land away from nature for cities and their airports, etcetera. In South Africa, President Jan Smuts insisted that mining companies put the soil they dug up back into the ground. He knew that if it was left out then there was going to be soil erosion.
I think that your question is answered.
please mark it as the brainliest answer
We illegally hunt and kill animals. We bring exotic species into habitats. All of these activities take resources and habitats away from plant and animals. Human activity often changes or destroy the habitats that plants and animals need to survive.
