In the concrete jungles of modern cities, millions of residents are facing a "disconnection crisis" from nature. This disconnection manifests not only in physical isolation, but also in dual psychological and physiological dilemmas. Whether it is escaping the burden of the reality through traveling or driven by an innate yearning or nature, the core points to one proposition: People in big cities must proactively build connections with nature, which is a necessity for individuals’ mental health.

In source C, Studies show that direct interactions with the environment provide the best mental improvements, but contribute to pollution and climate change. Today, tourism is responsible for one-twentieth of all man-made carbon emissions, with air transportation taking up most of the sector's emissions. And as population grew and traveling became more common, the carbon emission was expected to rose from 982 million tons in 2005 to a jaw-dropping 1,998 million tons by 2030. So therefore, nowadays people are actually destroying the environment when they are trying to experience it. This approach is unsustainable and worsens climate change. However, there is a kind of alternative approach. In Source A, studies prove visual reality to be the best substitute for traveling. It provides interactions with nature without going outdoors and can bring most of the effects people pursuit when traveling. And furthermore, it greatly reduces the harm and pollution these experiences make. In conclusion, by partially abandoning travel and switch to VR technology, people can have the psychological benefits from nature while protecting nature itself.

As traveling-based carbon emissions continues to rise every year, which polluted the air, making the travelers so hard to escape form the reality and letting the effects and gains of traveling dwindle, adopting virtual reality of nature to the explorers provides a  experience with low carbon production approach to refresh the Earth.
