Animal Population Decrease

                            Depopulation refers to the destruction of large numbers of animals in response to a public health or animal health emergency.
Wildlife refers to all the plant and animal species that survive in natural, wild areas throughout the world. Humans use plants and animals for nearly every facet of daily life. Food, clothing, medicine, souvenirs, pets, and building supplies are just some of the uses that have led people to rely on wildlife.                                          Humans fulfill these needs by overfishing rivers and oceans, poaching endangered animals, and overhunting important species. Wildlife exploitation is responsible of almost a quarter of the loss of wildlife biodiversity. We are taking more than mother nature can provide.

        ♦ Major Causes of Wildlife Loss

  • Poaching, 
  • habitat degradation,
  • climate change, 
  • invasive species, 
  • diseases→threaten to wipe out wildlife in large numbers

            1. Pollution

           All of this human development produces pollution. Waterways are polluted with runoff from manufacturing facilities, factory farms, and the gas and oil that collects on roadways. Mining practices discard unusable heavy metals and minerals into groundwater sources.Air is polluted by the fumes from traffic and burning fossil fuels. Pesticides sprayed onto crops inadvertently kills other plant species. Garbage and littering fill the land with non-biodegradable plastics that can be consumed by animals both on land and in the sea. All of these reasons and more explain why pollution is directly responsible for the loss of wildlife biodiversity. But, indirectly, it is responsible for more deaths because it causes global climate change. All of those greenhouse gases released into the air not only have a direct impact on the quality of air and water but they go on to trap solar radiation which leads to increased global temperatures, natural disasters, and glacial melting. Global climate change has exterminated all wildlife.


       2. Disease

Finally, disease among plants and animals is responsible for a loss in biodiversity. Disease is almost an aftermath of the aforementioned causes of wildlife loss because it occurs in unhealthy and unbalanced ecosystems. Although they are naturally occurring, an unhealthy ecosystem cannot fend for itself and fight off virus, fungus, and bacteria in the same way a healthy ecosystem can. Lower levels of biodiversity mean that the plant and animal community is less resilient to disease.

      3. Invasive Species

                Human involvement does not stop with these causes. Increased globalization means that people are now traveling farther and faster than ever before taking with them new ideas, business prospects, and finished goods around the world. While this sounds like a positive advancement for civilization, it also comes with negative consequences. This increased mobility has also allowed for the spread of non-native plants and animals to move into new areas. Non-native wildlife is referred to as invasive species and they are responsible for the loss of all wildlife and for threatening all endangered specs. Invasive species move into an area and quickly reproduce and spread. They outnumber native species, preying on them and competing with them for food resources. This decreases the biodiversity thereby changing the structure of the ecosystem.

                     ♦  What Can Be Done? 

  • Within urban areas, residents need to be educated and empowered to work at a local level to promote small scale conservation efforts.
  • Business owners need to be held accountable for the environmental degradation that their work may cause and further mandated to reduce and offset this destruction.
  • Policy makers on an international level need to tackle wildlife trade and poaching concerns.
  • National government should focus on converting their nations to renewable energy sources.
  • On an individual level, people need to focus on reducing, reusing, and recycling products, but since this problem is large, it cannot be fixed by one person. Action is necessary across boundaries and cultures, from the lowest levels of society to the highest. The problem can no longer be ignored.

Hey Ben

I find this topic being very educative. It is very important that we preserve our wildlife as its part of the diversity and natural heritage. Its sad that wildlife has been abused so badly in the last couple of years that some, sadly are at the face of being extinct. Well, the government and other bodies have invested into preservation and conservation of wildlife. Glad youve mentioned what can be done to save the drastic depopulation of our flora and fauna.

However its quite incomprehensible how these policies never work perfectly since they were effected many years ago. 

Maybe there should be some other questions, like how and whether the government funds effective conservation of wildlife and natural heritage, whether we as part if the community are doing enough in the challenge.

Maybe cases of illegal poaching could be charged as murder in courts of law to keep manage wanton destruction of wildlife.

Maybe something new has to be brought up if the drastic depopulation is to escalate to some acceptable number. Some tip by the way, maybe in your next post you can check out on that, and hold us at brief by telling us what your next post will entail. Good luck!

Hey Benito,

You've got a cool research on wildlife conservation in which according to research and also reality is that human beings completely take part in destruction of wildlife habitats like deforestation,polluting water and what a view, which can make animals contract diseases,die of hunger e.t.c.

Great Research!looking forward to the next post.

Hey Benito!

You did an awesome job on this research round! I think the lists and photos were a great job that made your information even easier to read/understand - great job! I also really admire how you decided to tackle a topic that is so current and important. The decrease of our animals in the world is truly frightening and you are right, this problem can no longer be ignored! Personally, I will try to be more conscient of my actions like you suggested. 

Here are some possible sources for your next round: 



Great job and good luck!


Hi Benito!

This is a very interesting topic, and I like how you really highlighted the fact that humans are responsible for this. I also liked how you organised your research into different reasons for animal population decrease. I too agree that this is a very big problem and that we need to take action. If we just let things get worse, it will not only affect nature but it will affect us, because we are reliant on nature and on our on environment to give us the resources we need to survive. 


Here's an article about that for you:


Good luck in your future research!


I look forward to reading your future posts,

Hi Benito!

Great choice for your topic!  This is something we don't really get taught about in school and it's important to know when we are negatively affecting something and that it needs to be fixed.  This, with so many other problems in the world is so scary. It's really sad that we humans have created a bi part of the reason it's happening and we are turning a blind eye and doing absolutely nothing about it.  People are happy to posts things on social media encouraging us to "save the animals" and like it and move on with their day.  Not to mention the fact that we are NOT taught any of this, we are not taught to aspire to fix climate change or the endangered animals, we are given basics: an accountant, a teacher, a police officer etc.  

here are a few links you hopefully find interesting:



Hey Benito! 

Fantastic job on this post! It was very organized and neat to read. I learned a lot through your information; how the wildlife is so endangered as of right now. As you spoke about pollution, disease and invasive species; it made realize something. We are capable of change but are not doing anything to change it. This truly inspired me to now look at this from a new perspective. 

Perhaps for a future round you could discuss the actions being held against these negative aspects. 

Here's a link that could possibly help you: 


Way to go
