There are troubles in measuring the actual extinctions increased by man. With the extincted species we got newly adapted species to replace. By average, living species live for 10 MYr average and we hardly measure the increase rate of extinction since we can hardly estimated a correct background extinction rate. For what scientist can say is, human existence become major factor of species natural selection process. Those that can adapt to coexist with human had greater chance of survival.

(A) List some of the main human activities that contribute to Species extinction. (b) Do you think such activities can be justified?
Main human activities contributing to species extinction include habitat destruction through deforestation and urbanization, pollution, overfishing, and climate change caused by greenhouse gas emissions. While some activities, like agriculture and industry, are essential for human survival, their environmental impact often outweighs the benefits, leading to irreversible damage to ecosystems. Justifying these activities is complex; sustainable practices can mitigate harm, but prioritizing short-term economic gain frequently leads to long-term ecological consequences. Ultimately, a balance must be struck between human needs and the preservation of biodiversity.

What is a reason that species becomes extinct?
Animal extinction is caused by humans, everybody knows that. The top reasons are habitat destruction, and hunting to sell body parts, like tigers for their fur and bone.I think habitat destruction is the top main reasons because it has more consequences over time since most animals will be unable to recover that space. There are also people who capture animals, to sell them later on to wealthy people who have nothing else to do with their money, but to buy endangered animal species, to illegal shows or circus e.t.c; So you understand, the main reason for animal extinction, is human intervention on their natural life, and environment.1. Human Hunting 2. Habitat loss3. global warming4.starvation1. Increased Competition2. Change in the Environment3. New Predators4. New DiseasesMostly habitat loss and over hunting are the main reasons, poaching endangered animals such as tigers.Survival of the fittest. They lack the ability to gather enough food to survive, or to live in the conditions they are in.This can be from something such as their food source being taken away or their habitat changing very quickly due to a natural disaster.
