Answer:
The “fact” that biological diversity—biodiversity—is declining and that humanity is ultimately responsible has become common knowledge among scientists, citizens, and policymakers. Biodiversity loss is the mantra for conservation; we are exhausting biodiversity on the planet at a far greater rate than it can replenish itself (1). Furthermore, these losses could greatly reduce the benefits (ecosystem services) that humans obtain from nature, such as the pollination of crops, absorption of carbon dioxide from the atmosphere, and provision of wild foods . However, is biodiversity truly declining? Remarkably, Vellend et al. export that, on average, the local diversity of plants has not decreased in recent decades. If anything, it has increased.
Vellend et al. searched the literature for studies that examined changes in local plant diversity. They found 168 studies from around the world, where the number of plant species had been counted, in over 16,000 plots in total, over periods of 5–50 or more years. They analyzed their global-scale dataset, finding an average 7.6% increase per decade in the number of species present in plots. This average was not significantly different from zero, so they concluded that there has been no overall change in local plant diversity, a finding that is extremely interesting.

Answer:
B. All of these are drivers
Explanation:
The populations of lot of amphibians, with rare exceptions, are constantly on the decline around the world. The main reason behind this is the human activity, as it has caused lot of changes, pollution, and dangers for the amphibian populations, which has led lot of amphibians to be on the verge of extinction.
The pollution, especially of the waters, has been a major factor for the decline of the amphibian population. Lot of very toxic chemicals have made the water unsuitable for living and poisonous, which systematically killed off the amphibian populations.
The habitat loss, as with any other group of animals, has left the amphibians without places to live. They have been left without their shelters, food sources, mating grounds, and they have started to die out.
The invasive species, especially the predatory ones, have also had big negative impact. The amphibians didn't had any defense mechanism against the introduced predators, so they were easy prey and their numbers rapidly went down.
Is there a better pic of that bc it’s kinda blurry and it doesn’t fully show the paper
