Brazil is home to 20 % of the known living species on earth

The correct answer is - True.

Brazil is the country with the highest biodiversity in the whole world, and in its territory are living approximately 20% of all of the known specie on the Earth. This incredible biodiversity in Brazil mainly is due to the northern half of the territory of the country, which is occupied by the largest tropical rainforest in the world, the Amazon rainforest, also referred to as the ''lings of the Earth''.

The Amazon rainforest in very big, and in it, every day new species are discovered and added to the very long list of species, be it from the flora and fauna branch. Brazil owns the biggest portion of the Amazon rainforest, and it has one of the most valuable assets in the world in it, but unfortunately, it is used in a very negative manner, where the rainforest is systematically destroyed, and along with it, lot of species of plants and animals became endangered or totally die out.

answer; ///i believe the answer is ( a hitch and signals);

it is very hard for the climatologists to precisely predict how will the global temperatures be changing so there's lots of models, some of which differ significantly, this is due to multiple factors, and probably the most important is the human activity.

humans have been a key factor in climate change around the globe since the start of the industrial revolution, and in the past few decades the consequences are becoming more obvious. there's lots of emission of pollutants in the atmosphere as well as changing the environment on the surface itself, so it's really hard to predict how will that go in the future because there's some countries that are reducing the damage and are going towards green energy, while others are stubbornly continuing with pollution and damages to the environment.
