\begin{abstract}
``Pressure and time.'' A momentous quote in a compelling movie from a
few decades ago interestingly pointed at some of the ingredients that
contributed to shaping the Earth. The movie set off from how to seep
through masses that appeared just too vast to be shakable or vulnerable
-- if not by deciphering their inner core.

~The planetary size and time frame of the Earth may have elicited a
perception of a durable, unbuckling living environment -- just because
``pressure and time'' to really affect it would have been out of human
reach -- supposedly. However, the Earth and environmental sciences have
long striven to alert contemporary societies that this is just
\emph{not} the case, as humans have been well exerting scattered yet
ubiquitous, planetary-scale pressure over a relatively brief time --
with consequential, durable effects.

~Rising global population, long-term migration shifts of continental
extents -- due to risks, climate, resources -- and unpredicted factors
-- from vulnerabilities to instabilities -- pressure on the environment
(natural and built) in unprecedented scale throughout human history. The
Earth sciences were born out of deciphering ancient life forms teeming
in an aboriginal environment, unfolding on a planet that could be
explained only by looking at the Solar system -- and at the inception of
the Universe.

Cross-disciplinary by nature, the Earth and environmental sciences offer
crucial tools to gauge location, economic turnout, and societal costs of
those very resources and fragilities. They also are pivotal co-actors of
intellectual stewardship bridging the gulf with sister disciplines well
beyond the remits of the physical sciences. From economics to
philosophy, and from history to literature, multiple, diverse and
concurring threats call for resourceful, multi-faceted mind- and
skill-sets where no single hazard may be really treated apart -- not on
societal terms.

Adapting a famous statement from the 20th century, evolution in a time
of poly-crises, multiple hazards, and accrued vulnerabilities is not
going to be a dinner party for contemporary societies -- especially as
they dwell a world perceived as increasingly richer in risks and poorer
in resources, with a growing population and across
instabilities.~\emph{Human Earth sciences} offer a bridge towards our
collective future -- as societies, continents, planets.
