Planet Earth 2- Episode 2 (Mountains)
Guest Blog by: Aine Mallon
The mountains provide a range of habitats for a diversity of different species due to their remoteness and tranquillity, in fact, the Himalayas have been described as one of the most hostile places on earth. In this report I will discuss the impact of life for the species spoken about and how many of their actions for survival relate to the similar reality people all over the world experience too. Also, I will discuss how the way these animals (and plants) have adapted to the changes of their environment and work together to be able to survive. There will be a discussion on how these changes to their environments are as a result of climate change and many human activities adding to this issue.
The sun-baked mountains of Arabian Peninsula
This mountain is home to a range to species but, our focus is on the Nubian ibex thriving here (they are known as mountain climbers and adults are well adapted for climbing mountains). They live in groups on the cliffs with other mothers and their young to prevent social deprivation between each other. They choose to raise their young on the steepest cliffs to provide safety for them, but it comes at a price. There is no water source available at these heights on the cliffs, meaning that they must descend into the valley which is 300m below them and risk their young’s life travelling down such a steep cliff for water. We see this in our world today, where mothers in Kenya and African children must help their mothers to gather water from their only source of water. Many people in developing countries must walk an average 3.5 miles to collect this water.
However, we as a nation have come together to help people suffering, many charities such as trocaire and events such as World Vision’s Global sponsoring walk or running marathons. This is done annually to continue raising money and awareness to bring a more equipped and cleaner water source for drinking for those who need it. Throughout our lives, we have witnessed different communities come together to help fight this crisis others face. From this, we know that the communities today are working together to battle the coronavirus. To show our support, to help the NHS, we do all we can by staying at home to prevent the spread of the disease. We also know the farming community has been working effortlessly to supply the supermarkets with adequate food supply for society. We are showing that coronavirus can be slowed down by following the guidelines and support our key workers.
During the winter months there appears to be a food shortage in this region and species such as the golden eagle will scan the slopes for food. This is not an easy task as there is much competition for food, and although the eagle is a bigger bird when it finds food, crows will be persistent to steal her meal and other bigger eagles may try to steal it. We do not face food shortages in society, but what we do see recently because of COVID-19 is a lot of panic buying. We have witnessed shoppers buying many more of the same item needed particularly toilet roll and baby formula for their food. This is resulting in the more vulnerable, elderly people of society shopping after the mad rush of panic buyers and being left with none of the necessities they need.
However, as stated in the previous paragraph, many people have volunteered to go out shopping for those who cannot go out during this time. We have also seen stores such as Iceland open a few hours earlier only to allow in the elderly that need to shop without the chaos of others.
Mountains of North America
Here grizzly bears will hibernate until springtime when they emerge however it was shown that, although it is rare, in these mountains’ avalanches can occur whilst they are hibernating. However, bears prepare their dens for such events, for example they ensure there’s two separate exits, keeping numerous breathing holes open into their den, and making methodical checks up to the surface occasionally. Like bears, people in society prepare their homes for all safety measures, for example in areas where it is prone to flooding. These defences include planting vegetation to retain water and constructing channels (floodway’s) and more modern flood defences can include dams.
As we have seen from the grizzly bear, we act the same by preparing our homes from protection of natural events. As COVID-19 is a new situation which many of us haven’t faced before, we are learning as a society of how to take more precautions. These have included staying 2 metres (6 feet) away from others when out in public, continuously washing our hands and avoiding handling money, so paying by contactless card when it is possible.
Here seasonal change is swift and dramatic with temperatures dropping to -65°C. The bobcat is a distinctive creature which remains active during wintertime. As it is difficult for the bobcat to find prey in the deep snow, it is forced to use the river for a food source. Due to the volcanic hot springs of the area, this is what heats the river and allows the animals that come out during winter, such as the coyote too, to find prey. Here we can see the environment working together to sustain the life of living things during the harsher winter months. How we can link this to our own lives, is if we look at the environmental impact from COVID-19. This change is slowing things down for people, but mother earth is healing whilst the rest of the world slows down. Unique changes in our world from reducing traffic, airplanes and tourism are allowing for a cleaner and healthier planet that we live on.
Impact from climate change on the mountains
Of all the mountain areas I have discussed, climate change from human activities is destroying their habitats. In the Andes, human encroachment is changing the highest summits. Whilst in the Rockies, rising temperatures is shortening winter hibernation and stifling the growth of food plants, negatively affecting the food chain. Also, in the Andes, rising temperatures are resulting in the glaciers shortening. As the snow retreats further and further up these peaks, it is limiting space for wildlife and a species that is declining greatly because of this is the snow leopard. Primarily they are an endangered species because of poaching and habitat loss, with a limited food supply for them in their environment.
High mountains are a bleak habitat for animal life. Food is scarce and the climate is very cold. Mammals living here have adapted to survive the bitter cold and most have thick woolly fur. It has been made evident that animals thriving in the mountains have adjusted their lifestyle to survive here and that it is possible to do so. Like the animal kingdom, we can work together as a community to help one another during this difficult time of COVID-19. Unaware of when the guidelines for lock down will be lifted, as discussed throughout the report, it is important that we care for those more vulnerable and hit by the disease and support our NHS team during this uncertain time.
