From Xi Jinping:

Second, we must accelerate the transition to a green and low-carbon development model

Upholding green and low-carbon development as a fundamental approach to resolving environmental problems, we will work faster to promote eco-friendly ways of production and life, and lay a green foundation for high-quality development.

Check it out and let me know what you think of Xi Jinping's speech.

Kelly, a dolphin, was rewarded with fish by her trainers for bringing them litter and dead gulls to clean her pool. She began hiding fish under a rock in her pool and used them to lure gulls, which she then brought to her trainers to receive more fish. She even taught her calf the same strategy.

Not only do the dolphins understand the meaning of individual words, they also understand the significance of word order in a sentence. (One of their star dolphins, Akeakamai, has learned a vocabulary of more than 60 words and can understand more than 2,000 sentences.) Particularly impressive is the dolphins’ relaxed attitude when new sentences are introduced. For example, the dolphins generally responded correctly to “touch the frisbee with your tail and then jump over it”.

Analysis reveals imported earthworm species have colonized large swaths of North America, and represent a largely overlooked threat to native ecosystems. The researchers warn of the need to better understand and manage the invaders in our midst.
