Answer:
Their gravity helps make life possible.
Explanation:
The Jovian planets are also known as gas giants and have had more of an impact on Earth than most Earthlings probably realise. During the formation of the solar system, these planets captured large planetesimals as moons and allowed the inner solar system to form less violently.
The gravitational pull of these massive planets also drew comets laden with ice from the outer reaches of the solar system towards the dry rocky worlds in the center. It was largely due to this slingshot process that Earth received its oceans.
Finally, the Jovian planets protect the inner planets today by deflecting asteroids and comets that might otherwise penetrate into the inner solar system and collide with Earth.

Currents involve movement of ocean water masses, driven either by wind or by differences in temperature, salinity and density. The most important from a human perspective are the wind-driven surface currents that move water in the uppermost layer of the ocean.
Currents affect humans in several primary ways. Currents help shape the climate in the areas where we live, create the right conditions to support abundant ocean life in the areas where we fish, and change weather patterns through periodic events like El Nino/La Nina.
Ocean currents also cause upwelling in many areas like off in the inland parts of North America, where surface currents taking water away from the shore cause nutrient-rich water to well up from the ocean deeps. The abundance of nutrients in these areas forms fertile ground for kelp beds and marine fisheries, which in turn furnish food for humans. Alterations in current patterns like the El Nino/La Nina cycle affect humans as well by causing changes in local weather patterns in the years when they occur.
