Unfortunately, climate change is only going to make these negative interactions between humans and wildlife more common. Already, while Australia heats up, wildlife is seeking refuge in towns. Kangaroos have swarmed human settlements in search of food and flying foxes have had to be hosed down by locals to stop them from overheating.
In southern Africa, more frequent droughts have meant thirsty elephants have raided villages to eat crops and pilfer water from storage tanks. Most wild animals are naturally averse to being so close to humans, so their incursions into our lives shows how desperate they are getting.
As climate change begins to take its toll on humans, by reducing crop productivity for example, we are likely to become less tolerant of these sorts of human-wildlife conflicts. Poor African villagers who have had their entire yearly crop destroyed by a herd of hungry elephants can hardly be blamed for wanting to get rid of the problem by killing the animals.
Sadly, elephants – like most other species – are already experiencing precipitous declines in their populations and this is almost exclusively due to human activities.

Climate change will exacerbate conflicts over natural resources between and within species – ourselves included. For example, some observers have suggested climate change was partly responsible for the Arab Spring uprisings, as droughts forced people from rural areas into overcrowded cities and inflamed tensions. If conflicts within our own species can’t be overcome, there is little hope for mitigating conflicts with other species – especially as resources become scarcer.
But there is a small glimmer of hope – there are effective methods to reduce damage caused by wildlife. Polar bears can be scared away from human settlements by flares and water tanks can be made elephant-proof. These technical fixes can help limit immediate conflict between wildlife and humans in the short term, providing much-needed relief in poor communities from the damaging effects of intruding wildlife.
Realistically however, technical fixes to human-wildlife conflict are only a temporary stopgap. To truly address the issue, we must focus on the root cause. Carbon emissions must be reduced – not only for the sake of wildlife but for the survival of humans too.
Wildlife habitat must be protected to ensure that species have space and food without needing to enter human settlements. Equally, societies must address their insatiable demand for natural resources, reduce overconsumption and excessive waste.
Much of this is easier said than done, of course. Without political will and sufficient funding all of this falls short. Global leaders must step up to the task – and it is partly up to ordinary people to pressure them to act. Movements such as the Extinction Rebellion and the school students organising global strikes against climate change are an encouraging start and must be built upon.
We need to cause an uproar like our lives depend on it – because they do. We have no planet B, as the refrain goes – and neither do the planet’s 8.7m other species.
