Last year I watched a documentary called Our Planet, which talked about the global impact of warming.
In recent years, due to the warming of the climate, glaciers in the Arctic have been declining, and there is a shocking number in the documentary: In 20 minutes, 75 million tons of glaciers have disintegrated. No more glaciers are expected in the Arctic by 2040. This will not only intensify global warming and sea-level rise but also affect the living environment of countless animals and plants.
In the northernmost part of Russia, hundreds of thousands of walruses live on sea ice, where they are closest to where they prey. However, due to the small area of sea ice, what can be seen on the screen is that almost every inch of living space is occupied, and densely packed walruses are stomped or crushed at any time, but more terrible situations are still behind …
Some walruses try to find space for activities outside the group, so they climbed 80-meter-high cliffs. This is an extremely difficult task for a 1-ton walrus that is used to sea ice, but in order to survive, to breathe a fresh breath Air, they can only do so.
Hundreds of walruses set foot on the cliff, and one after another fell or rolled to the bottom of the cliff, dying and waiting for death. Why do latecomers keep going down the cliff? Do you want to starve to the cliff or let go? Do you think they have more options? In a blink of an eye, the walrus corpse on the coast was startling …
“They are all at the forefront of climate change and are bearing the consequences.” But don’t forget that it is humans that cause climate warming, aren’t humans the indirect killers of walruses? !!
Although the end of the episode tells us that the process of global warming is slowing down and the creatures on the ice can take a breather, walruses and more animals living on the ice do not know when their homeland will disappear, and it is completely Unable to control their own destiny, as a netizen commented: human faults always require animals to pay!
Every time you watch these documentaries, you will feel that you are really small. In fact, most people know the importance of protecting the environment, but do you really do something for the environment? This is our planet, shouldn’t it be guarded by us?
How to deal with climate change?
From the current causes of greenhouse gas generation and the scientific and technological means mastered by mankind, the main way to control climate change and its impact are to formulate an appropriate energy development strategy, gradually stabilize and reduce emissions, increase absorption, and make necessary adaptations. Climate change measures.
The main ways to control greenhouse gas emissions are to change the energy structure, control the use of fossil fuels, increase the proportion of nuclear and renewable energy; improve the efficiency of power generation and other energy conversion sectors; improve the energy use efficiency of industrial production sectors, and reduce the energy consumption per unit product. Energy consumption; improve civil energy efficiency such as building heating.
Improve the energy efficiency of the transportation sector; reduce the destruction of forest vegetation, control the emission of methane from paddy fields and landfills, and thereby control and reduce greenhouse gas emissions such as carbon dioxide.
The main ways to increase the absorption of greenhouse gases include afforestation and the use of carbon sequestration technology. Carbon sequestration technology refers to the separation and recovery of carbon dioxide in combustion gases, and then deep-sea disposal and underground disposal, or chemical, physical and biological methods to fix it. The technical principles of carbon sequestration technology are clear, but whether it can become a practical technology is unknown.
Measures to adapt to climate change are mainly the cultivation of new crop varieties, adjustment of agricultural production structure, planning and construction of projects to prevent coastal erosion, and so on.

It’s so tragedy that the walruses lose their home and struggle for living. We need do our best to protect environment to prevent that kind of things happen again.

Yes, this story is too tragic. Of course, this is just one story in this documentary. We must take good care of the environment.

In recent years, climate change has become a more and more urgent problem. Animals living around the glacier are losing their homes, they are paying for human behaviors. Maybe we haven’t clearly felt the harm caused by climate change, but if we cannot suggest a solution as soon as possible, we will clearly feel the power of climate change.

I agree with one. This story is too sad. We should start to act as early as possible to prevent such tragedies from continuing.

Your article deeply impressed me. Climate change are degrading our living environments from many aspects. But a disappointing fact is : although people are willing to protect the environment, many of them are less willing to sacrifice quality of their lives for sustainable development. Thus I have the same opinion with you that updating the energy structure maybe a useful solution. If so, can continue to live as usual, without threatening the environment.

Thank you for your comments. We need to make our own efforts to stop climate change

Alas, this documentary is really disappointing and regrettable for humans. Developing renewable resources is indeed a good way. However, at least for the next few decades, fossil fuels will still be the most affordable because we cannot force most developing countries to pay for expensive new energy.

You are right. At present, fossil energy is still very cheap, so preventing climate change is very serious.
