地球进入了第6次生物大灭绝

The Earth Has Seen the Sixth Biological Mass Extinction

地球自距今5.4亿年寒武纪生物大爆发以来,由于环境变化等自然因素,已先后造成了5次生物大灭绝。尽管每次大灭绝使大批生物从地球上消失了,但也有些更能适应环境、更进化的生物保留下来并得到大发展,从而使地球上的生物一步一步地由低等进化为高等,而且最后成为最多样性、最繁盛的阶段。但自200年前工业革命以来,由于人类对生态环境的肆意破坏,已导致大批物种消失,使地球进入了第6次生物大灭绝。由于这次大灭绝的主要因素是人类引起的,因此其后果特别严重,如若不采取措施,最后灭绝的将是人类自己。

Owing to natural factors, biological mass extinctions had appeared for five times on the Earth from the Cambrian to Tertiary, including many biotical groups. Since the Industrial Revolution of two hundred years ago, human activities have caused serious deterioration to the environments and resulted in the sixth mass extinction. If human beings continue to deteriorate the environments, the consequence will be unimaginable.
