Cultivated Mushroom

O cogumelo-de-paris (Agaricus bisporus), nas suas diferentes fases de crescimento — botão branco, cremini e portobello — é o cogumelo mais cultivado no mundo, representando aproximadamente 40% da produção mundial de cogumelos. Domesticado a partir de espécies silvestres de Agaricus encontradas em pastagens da Europa e da América do Norte, é cultivado comercialmente em ambientes controlados sobre palha e estrume compostados. Rico em vitaminas do complexo B, selênio e fibras alimentares, é um dos fungos nutricionalmente mais versáteis na culinária humana.

Polar bear

O maior carnivoro terrestre da Terra, o urso-polar pode ultrapassar 700 kg e e encontrado pelo gelo marinho artico, do Canada ate a Russia. Mamiferos marinhos altamente especializados que dependem do gelo marinho para cacas de focas e focas-barbadas. Excelentes nadadores capazes de percorrer grandes distancias em aguas abertas. Classificado como Vulneravel, com populacoes sob severa pressao devido a rapida perda de gelo marinho artico causada pelas mudancas climaticas.
