Well, obviously poaching is one process which has contributed to species becoming extinct. Many of the earth's endangered species were made possible due to poaching in which humans, most of the time, illegally hunted species resulting the slow decline of animal populations. You may wonder, why? Why do humans hunt elephants, giraffes, lions? etc. Well, ka-ching ching of course! Ivory, obtained from slain elephants are sold in black markets for hefty prices. Animal skins of rare animals will make the richest man cry! It's all about the $$$ these days what with the National government favouring high income earners and all. I mean, that's a pay rise to every single MP. Although Labour disagrees with them in the public eye, they are probably secretly enjoying the benefits. Excuse me. Off topic. Another process leading to the endangerment of species is the change in climate which is caused by none other than human beings. People like you, reading this comment right now. Yes, Pollution does have nasty surprises for human kind and animal kind (?). Well, if truth be told, I am not a geography student so let me just end the comments there.

There are many processes that has led to species becoming endangered a lot of them due to human activities such as population growth, economic development and many more. Although humans are to blame for about 80% of the damage sometimes these processes can happen naturally, such as deforestation (bushfires and natural disasters).
Deforestation is the process where trees and natural vegetation are removed or destroyed. The area is then converted into a non-forest use. Man-made causes of deforestation can be overflowing of dams, logging, clearance for houses and businesses, agricultural purposes, etc. Natural made causes can be extreme natural events or bushfires. Because our population is increasing and more people decide to live in urban areas rather than rural areas therefore more land is needed to be cleared to build more houses and more cities leaving a lot of our species homeless and forced to adapt to unnatural habitats causing them to die out, ultimately causing extinction. For example the orang-utan is classified as endangered due to deforestation. Their homes have been destroyed for the replantation of palm trees for luxury food for humans such as chocolate, KFC and others. Also because of these heavy machineries, they are causing pollution to our species homes; this includes noise pollution, visual pollution, water pollution and most importantly air pollution. These types of pollution can affect the reproduction of these species causing a decline in their population.
Another process that has led to species becoming endangered is urbanisation. Urbanisation is where people move from rural areas to urban areas, this is also known as “rural flight”. The cause of this move could be because of job opportunities, educational or medicinal reasons and population growth. Population growth, itself, is a process that has also led to species endangerment. It is the increase I population. This is a major cause for urbanisation as the numbers of immigrants and births are increasing more each day endangering the lives of more species. Due to urbanisation more cities need to be expanded and more modern day buildings built for the convenience of humans, this means that more land is needed to be cleared for this to start happening leaving more of our species homeless and vulnerable for hunting. Urbanised people are also endangering our species by using parts of their bodies for luxury items. For example the blue whale has been classified as endangered due to a reduction in population based on an index of abundance and actual levels of exploitation. Their fat (blubber) is often used in products such as make-up, soap, etc. Their meat has also been sold at Japanese markets, illegally. Because more people wish to lie in urban areas, products such as soap are necessities for them which could cause extinction for our whales.

One process that leads species to endanger is Deforestation. Deforestation is the destruction or removal of forests and natural vegetation. The removal of these forests is then converted to a non-forest use, urban areas, agricultural areas and timber for wood due to demanding companies and people. Excessive use of groundwater, building of dams and climate change are also cause of deforestation. Sometimes deforestation can occur naturally due to disasters, extreme natural events or bush fires. How deforestation lead species to endanger? Deforestation has destroyed the natural habitat of many species causing a rapid decrease on their population. Marine lives in the Amazon are also affected by the deforestation as immense 30ft trees crush them. Specific plants are also at risk of extinction if they are destroyed, companies plants only one or two species of trees to make up for what they removed. Certain animals need a specific tree to live or raise a family when humans plant only one single tree, it might be hard for them to adapt, ultimately causing extinction.

Another process that leads species to endanger is Urbanisation. Urbanisation is the social process in which people move from rural areas to urban areas, with population growth leading to cities expanding and societies becoming more urban.
