  • 00:00:00 - 00:05:00

    A young calf growing up on the Savannah faces numerous dangers, particularly in its first year where a third of calves don’t survive due to various threats, highlighting the severity of life in the grasslands. The environment is dominated by grass, which plays a crucial role in the survival of numerous herbivores and predators alike.

  • 00:05:00 - 00:10:00

    The grasslands support massive herds and large animals, but they are also subject to extreme weather conditions, including floods and droughts. The relentless cycles of nature challenge all wildlife residing there, making survival a constant struggle as temperatures and climate variability affect food availability.

  • 00:10:00 - 00:15:00

    During severe conditions, bison struggle to endure frigid temperatures and scarce food resources, becoming vulnerable to predators like wolves, which exploit their weaknesses. The dynamics of pack hunting emphasize the threats faced by the young calves when separated from their herd.

  • 00:15:00 - 00:20:00

    As spring arrives, temperatures drastically change and thunderstorm seasons begin, bringing heavy rains that lead to flooding. While adult animals benefit from the revitalization of grasslands, young calves can struggle with deeper waters akin to drowning, marking a critical period for new life amid a hostile environment.

  • 00:20:00 - 00:25:00

    Newborn prey animals, such as Thompson gazelles, face immediate challenges shortly after birth, as predators like cheetahs pose deadly threats. The instinctual behaviors of mothers and their young are illustrated, showcasing the innate dangers that exist in their first hours of life.

  • 00:25:00 - 00:30:00

    Calves that manage to survive initial threats can thrive in productive grasslands. However, historical changes in animal populations, such as the depletion of bison herds, create a complex backdrop as competition for resources intensifies due to climate changes affecting ecological balance.

  • 00:30:00 - 00:35:00

    During the mating season, experienced bulls engage in fierce competitions for breeding rights amidst harsh conditions that further complicate the survival of bison. Seasonal weather shifts particularly impact the energy levels of males, with direct implications for the next generation of offspring.

  • 00:35:00 - 00:40:00

    The dry season becomes increasingly challenging, requiring herbivores such as elephants and hippos to travel further distances to find sustenance, risking encounters with predators and requiring resilience to survive harsh realities. The interconnectedness of wildlife emphasizes resource scarcity during these critical months.

  • 00:40:00 - 00:47:22

    In extreme drought conditions, competition for limited water resources leads to violent clashes between animal groups, such as baboons. The struggle for survival showcases the harsh reality of aggressive interactions that can occur during periods of scarcity, affecting relationships and social structures within species.

  • 00:38:09
    prone countries in the

    world and it's getting

    worse as our climate

  • 00:38:35

    with little to drink out here they're
  • 00:39:32
    forced to the same water hole below the

    cliff but when two bands meet it nearly
  • 00:39:43
    always ends in

    drink but the band at the water hole is
  • 00:40:48
    stronger this is how Wars begin
  • 00:41:15
    the best survival strategy here is to
  • 00:41:18
    form super

    bands bigger than the opposition

    you

    The Outsiders are forced to

    retreat but not fast

    enough these baboons use battles to
  • 00:42:17
    steal females from each other
  • 00:42:27
    the winners expand to their
  • 00:42:31
    ranks while The Outsiders grow even
  • 00:42:35
    weaker
  • 00:42:59
    all they can do is buy their

    time and try
