3 . People representing over 100 countries met virtually in Kunming, China, last week to discuss how to protect Earth’s biodiversity(生物多样性). This CBD Meeting（also known as COP15）ran from October 11 to 15, 2021.

There are so many different species. Sadly, species are disappearing all the time. One recent study suggested that around a million species are in danger of extinction. Like the climate crisis, the world’s loss of biodiversity is caused mainly by humans, who don’t always cooperate. Climate change is playing a part. The biggest way humans are causing biodiversity loss is by taking over the homes that all kinds of plants and animals depend on and using them for things like farming, mining, or cutting down trees for wood. Humans are also harming the oceans by fishing too much, and by severely polluting the seas with plastic, oil, and other chemicals.

In 1992, the world’s countries began signing an agreement called the Convention on Biological Diversity (CBD). The meeting is being held in two parts. Last week's meeting discussed plans and goals for protecting biodiversity through the year 2030, which led to a plan called the “Kunming Declaration”. An in-person meeting will be held in Kunming next May to formally agree to the plan. One of its big goals announced in Kunming is to cut dangerous chemical pollution from farming. The plan also includes asking governments to cut up to $500 billion of their support for activities that hurt biodiversity, like some methods of farming, and producing fossil fuels.

CBD organizers hope the world's countries are really ready to work on biodiversity problems this time. In 2010, over 100 countries agreed to a 20-Part Plan to protect biodiversity by 2020. But none of the plan's 20 goals had been consummated by 2020. Solving the problem doesn't depend on what countries say they'll do. It depends on what they actually do.

4 . Rome can be pricey for travelers, which is why many choose to stay in a hostel (旅社). The hostels in Rome offer a bed in a dorm room for around $25 a night, and for that, you’ll often get to stay in a central location (位置) with security and comfort.
