Almost 15,000 environmental scientists from 184 countries have signed a letter called “World Scientists’ Warning to Humanity: A second notice” to attract attention towards climate change. This second notice came 25 years after the first letter in 1992.
The second letter is a desperate plea by the scientists’ to save the earth, as their first warning fell on deaf ears and the situation has further exacerbated. In the list of ecological threat featured in the first letter, other than the repair of the ozone layer, all the other predictions were ignored.
The uncontrollable growth of population is the primary factor for ecological imbalance and various societal threats. Humanity is fast consuming the limited yet bountiful resources that nature has to offer due to exploding population, they warned in the letter. They express concern as media, scientists and influential individuals are not doing enough to gather attention to the problem.
Another major issue is the constant rise in global temperature. One of the arguments against climate change that climate change deniers have is that there is no substantial rise in global temperature since 1998, but that has been debunked by the data provided by NASA.
NASA reported that we have been breaking global temperature record every year. In 2016, the temperature increased by 0.12°C more than the previous record of the hottest year. That record was set in 2015, which broke 2014’s record by 0.13°C. The rise in temperature has serious implications as the polar ice caps are melting at an alarming rate.
The signs of ecological damage can also be seen in the depleting forest area, increase in CO2 emission, a significant decrease in freshwater resources, increase in dead zones.
The letter states that since 1992, CO2 emission increased by 62 percent, the overall temperature increased by 29 percent and wildlife decreased by 29 percent.
The years before and after 1992 talks are denoted by grey and black lines, respectively. Other than ozone layer depletion, none of the other aspects look promising. According to the letter, marine catch has been significantly going down as fishing efforts are increasing.
With the increase of population, cars have been increasing which shows the increase of CO2 emission. Population increase is also the reason for depletion of forest, as land is being cleared to make them habitable areas.
The letter offers solutions to the problems too. It says that necessary reservations and responsible funding can be done to cater to the needs of both aquatic and terrestrial animals. Preservation of forest can be done by halting the transformation of forest land into habitable environment.
By ensuring education to both men and women, food waste can be decreased. People can adopt a more plant-based diet. Education will also help in the reduction of fertility rates, thus bring the population down. Children can be taught from the very beginning about the usefulness of nature and the need to protect it.
Substantial progress has been made by humanity previously. Due to investment in the education of the girl child and their subsequent rehabilitation, UN reports there is a decline in fertility rates in various regions. The rate of deforestation has decreased slightly. The growing use of renewable energy is also a welcome change. The Second Notice hopes to bring attention to the fundamental and urgent needs of nature for the future of the earth and the coming generations.
