Detailed explanation-2: -They cover about 30 percent of Earth’s land surface, while accounting for 50 percent of plant productivity. As much as 45 percent of the carbon stored on land is tied up in forests. Forests cover 30 percent of the Earth’s land.

Detailed explanation-3: -There are over 510 million square kilometers of area on the surface of Earth, but less than 30% of this is covered by land. The rest is water, in the form of vast oceans.

Detailed explanation-4: -Covering more than 30 percent of the Earth’s surface, the Pacific Ocean is the largest water mass on the planet. With a surface area of more than 155 million square kilometers (60 million square miles), this ocean basin is larger than the landmass of all the continents combined.

Detailed explanation-5: -Forests cover just over 30 percent of the global land area, yet they provide habitat for the vast majority of the terrestrial plant and animal species known to science.
