First, the problem of the earth's environment is actually closely related to everyone, rich or poor.
A sudden epidemic in 2020 changed the whole world and the life track of countless people! This further triggered us, right? Human destiny * * * same body? I am deeply impressed!
In 20 19, the biggest locust plague occurred in Africa in decades. The number of locusts covered the sky, and everywhere they went, food crops were' eaten clean', causing a serious food crisis for millions of people.
A few months later, Australia suffered the worst forest fire in history, burning more than 65.438+million hectares of forest, causing nearly 3 billion animals to die or be displaced. Rare droughts and record high temperatures have all contributed to the crisis. All this seems? Natural disasters? Behind, actually more? Man-made disaster.
On September 10, the world wide fund for nature (WWF) released the latest issue of "Earth Vitality Report 2020", pointing out that since 1970, the species population size of mammals, birds, amphibians, reptiles and fish monitored worldwide has decreased by 68% on average (as of 20 16)
This data shows that a new round of extinction may have begun? In the past half century, the average decline of species population by 68% is a disastrous trend, which is a strong proof that human activities have caused damage to nature.
Another report published in the Proceedings of the National Academy of Sciences studied the biomass of the earth, and found that 96% of all mammals on the earth are domestic animals and humans (60% and 36% respectively), and wild mammals only account for 4%. Since the rise of human civilization, 83% of wild mammals and 80% of marine mammals have become extinct. Due to habitat loss and degradation, including deforestation caused by human food production methods, the number of land species has dropped sharply.
Second, when the crisis comes, it is time for mankind to wake up and try to change.
If nothing changes, the population will continue to decline, which may lead to the extinction of wild animals and threaten the integrity of the ecosystem on which we depend.
A study by the Global Footprint Network shows that although we only have one earth, at present, human beings are using the resources of 1.6 earths to meet the products and services we need every year. Overdraft year after year makes the natural environment worse and all kinds of resources are on the verge of exhaustion. If it continues, it is only a matter of time before the earth's ecosystem collapses.
From now on, human beings need to wake up and do something for the environment, because this is self-help. Of course, human beings don't want us to repeat the mistakes of dinosaurs.
From now on, eat more vegetarian food, choose foods that will not lead to deforestation, buy more locally produced foods, and reduce the losses caused by processing and transportation. Reduce the use of disposable tableware, reduce the use of plastic bags and save food.
