The development of engineering and technology is also a key factor affecting global environmental issues, such as global climate change and the disappearance of wildlife. The world's industry emits more than 50 billion tons of carbon dioxide every year, and the burning of fossil fuels is the leading factor. The resulting climate change is expected to continue to have a huge impact on humans and wildlife for decades and beyond, putting millions at risk.

Let's face it, climate change is already killing an estimated 150,000 new people a year, according to a World Health Organization working paper.

The development of engineering and technology not only affects the climate, but also causes the extinction of species. A large number of wild animals around the world are affected, such as the destruction of forest vegetation by industrial development and fishing and other production activities in industrial production. Since the development of industry, the extinction rate of species in the world has increased by 100 times compared with the natural level of the natural world.

Of course, as people gradually realized the impact of industrial production on the natural world, the development of engineering also began to help solve global environmental problems and played an important role. For example, in the context of global environmental change, the efficiency of energy use has been greatly improved and new energy has been developed and used. These new technologies have played an important role in reducing greenhouse gas emissions and sustainable development of human beings. Other engineering technologies also enable human beings to have relative advantages in resisting natural disasters. Facts have proved that simple technological development and innovation cannot solve human problems and must be applicable to human beings and nature.

In addition to these problems, the lack of resources has also become an obstacle for human beings to solve these problems. We can make a comparison between human resources allocation and military expenditure to better judge which resources are more beneficial to human beings. The Institute For Policy Studies, For example, published a report comparing the us budget For "military security" with that allocated to "climate security" and found that the military budget is 88 times larger than the budget For addressing environmental issues. A similar study by the renowned British think tank Scientists for Global Responsibility (SGR) compared the government research and development budgets of the world's richest countries and found, unsurprisingly, a serious imbalance between military and renewable energy research and development spending. What is the most important question for human beings? It's worth thinking about.
