as sad a it be and whether the researcher not filmmaker and have be there or not he would have die . these men and woman be research the life of the meerkat and be take great care to not interfere with their way of life . it be the harsh reality that be nature . like when len and squiggy die and i cry my boyfriend have to tell me that even if the researcher hadn not be there and this hadn not be broadcast it still would have happen . that be what make this show so great . it be heart wrenchingly sad when something bad happens but so amazing when something good happens . the way these little creature survive surround by such a harsh environment while it be truly amazing . and like in nature a in life people die and we already mess with nature enough and through urban expansion and deforestation for the researcher to keep a meerkat alive that would have die in there absence would be bad . it would mess with the meerkat and the kalahari delicate way of life . so while yes this show have sad scene that a researcher could prevent and it be the hard fact of life in the kalahari and it be an amazing show .
