The situation of animals in the wild


Natural disasters are one source of animal harm that wild animals are particularly vulnerable to. Earthquakes, hurricanes, volcanic eruptions, tsunamis, and natural forest fires can have devastating consequences. Even when it would be possible to help them, most animals affected by natural disasters are left to die or to endure debilitating injuries that could have healed with... Read more


In nature, the ecosystemic relations in which an organism causes a harm to another one for his or her own benefit are called antagonistic ones. The main example of antagonistic relations are those in which one organism nourishes by harming another one, in particular by eating it. The two main instances of these relations are parasitism and predation.   Parasitism The term... Read more


There are many different diseases which affect non-human animals, and the harm they cause is just as diverse. As we all know, diseases can be very painful. In fact, we often fail to realise that it may be possible to vaccinate or treat animals that are slowly killed by disease and avoid the harm caused to them. This is explained in our page Vaccinating and healing sick and injured... Read more

As explained in our section on the general reasons for wild animal suffering, animal populations will grow as much as they can until limiting factors put a stop to their growth. Generally, most of the decline in growth comes not from fewer animals being born, but from more animals dying. One of the most important factors limiting the growth of animal populations is the...

Wild animals are vulnerable to an enormous variety of threats in nature. The threat of physical injury is one of the most common. Nonhuman animals are often injured, sometimes resulting in death. The actual wounds may kill the animals, or their injuries may cripple them in ways that are fatal, such as certain types of mutilations. In other cases, even though they survive, their... Read more

Weather is a major factor in determining whether animals can live and thrive in certain areas. Temperatures, in particular, dictate which animals can live in which regions. If temperatures are too low or too high, habitation by animals of certain species may prove to be impossible. Temperatures that are within the perfect range for some animals can prove deadly for others. In fact,... Read more
